Salt water fish tank filters?

Question

Now I need help with the filters. It’s a 35 gal salt water tank that was a fresh water tank not filled yet. I was told I could use a Bio wheel, but after looking into it they seem to have alot of faults, as the wheel stops turning from time to time, and if you loose power and the wheel dries out you’re screwed. I have a Aqua Pure 200 that is rated very good for all 3 types of filtering that I used on my fresh water tank that worked very well. I know the filter system in a salt water tank is somewhat different then fresh, but I was told again that the AP200 along with a powerhead would be fine for that size tank, was I informed right? To set up my tank I plan on using the sand sold in the store, and live rock, then let it cycle for a few weeks. Is that enough to get the Bio going? Or do I need to do anything else? I was also told I do not need air stones in a salt tank as I did in fresh water tank as long as I have a powerhead?

Answer 1

Correct. Biowheels are not very reliable especiall for a salt tank. I personally use back pack filters on my tank with protein skimmers. However one of my 30 salts has a whisper filter no power heads and no skimmer and it is the oldest tank I have.

AP200 and a power head are fine.

I will warn you however, forget what you know about fresh water since salt is a different beast. a MINIMUM of 6 weeks your tank will have to run empty to have enough bacteria to support salt fish and only the lower hearty end fish like damsels. NO INVERTS. Your live rock as well is best to WAIT. and there are reasons for that. LIVE ROCK will not cycle your tank faster than mother nature allows. 6 weeks with or without rock. It will take a minimum of 6 months before you can buy things like anemone's, tangs triggers, sweetlips etc. You WILL loose your fish. It takes that long for the total bio to kick in. DO NOT let anyone tell you differently.

Here is a salt water how to for newbees. I hope it will help you.

Some of this may seem mundane but it is what I tell everyone when starting a salt tank.

Congratulations! At least you are starting on the right foot. Figuring out what you will need to get started. First and I would like to stress this one word, PATIENCE.

First step for your tank is figuring out where you are going to put it. Remember with a salt water tank, you are going to have to leave room behind the tank for access, filters etc. About 8-12 inches. (This will also help to protect walls from salt evaporation. I'll explain later) Once you have that, we are ready to start.

Do you have a local fish store to trust? One that relies on good fish keeping and good advice to stay in business. Find one even if you have to drive a few miles out of your way. They can be a large asset when it comes to fish.

Do you have any ideas on what you might want to keep? Or is this a "we'll start with a blank canvas and see where it goes?" thing?

To start, a regular hood, no special lights will suffice for now. (until you see if this is what you really want to advance to)

To start, you do not NEED a skimmer. They are prefered but, my 30 gallon has never had a skimmer or power heads and still doesn't. I hate to use the word cheap, just less expensive. And you can still have a healthy tank.

A rear whisper filter designed for a 75 gallon tank will suffice for now. This will run around $50 at walmart of all places. Your best bet is to shop around. You can if you choose to go with a back pack filter which come preequiped with a protein skimmer for around $150.00. This could save time and money later when upgrading.

For a beginner, I would suggest dolomite (Crushed coral) for the bottom of your tank (Easier to care for). If you are not going to be runninga protein skimmer, this will make cleaning much easier. You will also want to get a gravel siphon for cleaning (these can range from a couple of bucks to upwards of $50. You don't need anything fancy, just a siphon). A heater is a must $10-15), thermometer $1.95 In the tank only a floater of one that attaches doesn't matter. It should be placed the farthest from your heater as possible.) A hydrometer These can run from a few dollars and up. Just a floating hydrometer is fine. around $4.00. Some packages of salt you will purchase sometimes come with a hydrometer, so this may help. Instant Ocean makes a quality synthetic salt. ($22.00). (When you start moving up in the salt water I would suggest switching to Red Sea Salt.) Power heads are beneficial, but at this point not necessary. They can be added on at any time. Get a quality Dechlorinator. (DO NOT USE start right or stress coat in your marine tank) AquaNova + is a good dechlor and it also adds back trace minerals to the water. One or two 5 gallon buckets. $2.29 each at home depot.

Ok I think we are ready to start. Be sure your tank is clean. You can use a salt water mix to clean your tank. There is also an aquarium cleaner you can buy but for your tank, a mix of 1/2 cup of salt dissolved in a gallon of water will do. (no specifics here.) Clean the tank rinse and let's get started.

If you chose to use the dolomite you do not want to use more than will cover 1 1/2 - 2 inches across the bottom. (Sand will require the same) Use a kitchen sive and clean the gravel by rinsing it. Dump the gravel into the bucket and swish the heck out of it. Drain and rinse again.

(You will only do this if you are using dry dolomite. LIVE dolomite and live sand do not get rinsed)

Pour the gravel into the bottom of your tank. Doesn't need to be flattened yet since you are going to be dumping water into your tank and this is going to dislocate it anyway. Using your 5 gallon buckets, fill just about 4 gallons or 4 1/5 depending on how much you can lift. Add the required amount of Dechlor and then the salt. (Usually 1.5 pounds or 24 oz per 5 gallons, however I have never used that much to obtain a 1.022 gravity in my tank.) I start by adding a cup mixing to disolve (and I use warm tap water here) I will check the hydrometer to see how far off I am and either add more salt or more fresh water. Since you are setting up your tank, obtaining an exact 1.022 is not that important right now, getting close is. Continue dissolving salt and new water until your tank is about 3-4 inches from the top. Attach your filter (be sure it is rinsed well as well as the filters) if you choose to use a rear filter. Even so a back pack filter also needs rinsed. Now we have water movement.

I did not mention anything about live rock or any other items for your tank yet. At this stage since you REALLY should not try to cycle your salt water this early with live rock. If you only knew what things grow on and in the rock, don't waste your money now. It really isn't needed. Now that your tank is running. Check the water with the hydrometer. you should be pretty close to your 1.022 range. Slightly higher or lower isn't going to matter. Turn your heater on and set it for around 78. Finish topping off your tank with salt mixed water. Don't forget to add dechlor to every bucket. Congratulations, your tank is now set up. Now comes the waiting. And you will wait. To aid in the tanks cycling, but does not replace cycling, take a few pieces of raw fish or shrimp, chop them up and toss them intothe tank. This will help the bacteria establish more quickly leading to a healther tank later. Get a notebook. Markdown the day you set your tank up and what you did and what you used. Do this with water changes and tests. This way you have a record of what was done.

Let it run. Continue to run the lights during the day and off at night. After about a week, check your water quality. I would suggest a really good test kit, and strips. I use the strips (I call them dummy strips since they are very broad ranged and are not accurate enough for fishkeeping) to initially test. Then I compair them with what I get from my water tests. I mark the results down in my note book with the day. If you don't trust yourself enough to read the water, take it to your LFS. They will do it for you. Your tank will have to run a minimum of 6 weeks with nothing in it. Do not try to rush this process. Salt water is not the same as fresh water. Shrimp, anemone or even fish are less tolorent of water conditions.

If you really MUST have something swimming around, after 3 weeks, you can buy a black mollie or a couple of guppies. They will live fine in your tank at this time. They are the only fish to attempt. Placing damsels would kill the damsels since they are not the same kind of fish mollies and guppies are. You really do not need to do any water changes during the break in time. If you are showing spiking of nitrates, you may want to do a 20% water change. After your 6 week break in period, test your water. If all the parmiters are ok, you can begin with the lower end fish. Damsels. DO NOT TRY to place triggers or tangs or puffers into your tank. The bacteria is present, but not established and it will kill these fish. If your damsels are doing fine in two weeks, you can start adding live rock to build up your substraight. You can buy as little as pound or ten pounds. You can buy dead corals, fake corals, or whatever you want to decorate your tank. Your tank will need to sit for a minimum of 6 months before you can attempt the higher end fish.

I test my tanks every three days. I only do a water change of 25% once every three to four weeks. My tanks are established however and are pretty much on their own.

A few rules of thumb when dealing with salt fish. Keep your hands out! The more your hands remain out of the tank, the better your fish will be.

DO not spray anything in the room your tank is in.

Now you can start thinking about breeding brine shrimp, and what other fish you are interested in getting. Remember to do your research, since fish require different lighting, water paramiters and are or are not compatable with reef, invertabreas etc.

Good luck. If you have any additional question feel free to email me.

PS I will be traveling for a tourny this week and may not have a lot of access to the PC. I will get back to you.

Answer 2

The aquapure should be good for a start - I had a double-chambered hang-on-tank and two powerheads (1 high, 1 low) when I started my first saltwater (a 29 gallon with live rock). Just make sure you have adequate water movement (5 - 10 times the tank volume per hour with the combined gph ratings of your powerhead and filter - a little more won't hurt). A second powerhead could be used to create a cross-current. At some point, you should look into getting a protein skimmer for your tank as well. I'd let the tank cycle for 3-4 weeks and check ammonia, nitrites (both should be =0), and nitrates before you add fish. The actual amount of time will depend on the amount and condition of your live rock, so if you use a test kit to check water chemistry, you'll know when the time is right.

Try adding some peaceful (but hardy and cheap) fish first - most people start with damsels, which are cheap and hardy, but most are very aggressive once they've had the tank to themselves!

Answer 3

I am now under the impression that with time and effort you can do anything; I am not sure if you just got the tank or the tank with all the supplies; sand, salt, filter, heater, light , piece of live rock about 6.99 a piece or 6.99 a pound depending on type of rock; hydrometer to test the salt level; test kit to test for nitrates etc ; de-chlorinating chemical; water evaporates , salt does not so when you make water changes you don't add new salt; small crab/snail to clean up the sand; protein skimmer; I just bought 2 clown fish(Nemo) for 12.99 each and damsels 3 for 9.99 ; it will be a cost to set up ; if you want it bad enough , give it a try; limit the number of fish to 2 ; I have a 29 gallon tank and have 4 fish , 1 crab and a starfish ; hope this helps ; I love mine !!

Answer 4

you could try what you have, if you don't think it is doing the job I would recommend a fluval filtration system, they are a bit more expensive but there is minimal maintenance on them and they work soo good. It also depends on the kind of fish you are going to be putting in. Small reef fish are pretty clean but if youre going to have something like a puffer then you really need some serious filtration. I converted my freshwater tank over to salt with my existing filtration and it was fine until I got mr. puffer, he was such a dirty boy I had to upgrade. Also of course the amount of fish you have in there will make a difference in what you need.
