Do i need to add salt in my tank when i change 25% water once a week?

Question

I have some mollies in my tank, i am changing 25% water once in a week. If i need to add salt then how much salt should i have to add weekly?

Answer 1

You add salt to the water you add when doing a water change, but not when replacing evaporated water as the salt doesn't evaporate. For example, if you have a 10 gallon tank and are replacing two gallons, add two level teaspoons to the new water, stir it up, and pour it into the tank. Mollies can live in marine aquariums, so you don't have to worry too much about how much slat is in the water, but you can buy a simple hydrometer to check the salinity if you are very worried. Cheap hydrometers can be a bit off. Check the water in your tank as it is now, and try to meet that reading from now on.

You should add salt based on what you took out of the tank. Not what you put in. If the tank is only molly and other livebearers then I wouldn't worry to much exactly how much salt you have unless you have over 1-2 teaspoons of salt in the tank. Note 25% weekly water change shouldn't be needed. I'd only be doing that big of change if my tank hadn't cycled yet, I was over stocked, or under filtered. 10-20% is recommend if you levels of nitrate, and ammonia are stable.

Answer 3

Are you talking about a saltwater tank or freshwater? Either way, you should not be doing a water change once a week. Changing the water that frequently can reduce your levels of beneficial bacteria, causing your tank to go through mini-cycles. This really stresses your fish out.

If you have a saltwater tank, you may need to add salt each time you change the water, unless you have an unusual amount of evaporation. You should have a hydrometer to measure your salinity. Measure it before you add water and then figure out the salinity of water you need to add.

If you have a freshwater tank, you can add salt each time you change the water as long as you aren't adding more than 1 tablespoon per 10 gallons. However, if you are changing the water as frequently as once a week, this might be over-kill. If you can get to a point where you are changing it once a month, it's ok to add the salt each time--it will help your fish fight the stress of the water change.

Answer 4

If you are removing water from the tank you are removing the salt so yes, you should add salt if you want to keep a relatively constant salt level in the tank. Generally, 1-2 teaspoons per gallon is recommended. So, if you remove two gallons of water you will prepare two replacement gallons of water with 1-2 tsp of salt. Please note that top off water (water you use to replace water lost to evaporation) should NOT be prepared with salt. The salt does not evaporate in this instance, just the water. Mollies do really need salt in their water but I would not recommend this for all freshwater tropicals.

Answer 5

It's a good idea to try to keep your salt level fairly even. A really bid jump or drop in salt levels could hurt your fish. If you can remember what amount of salt you used when setting up your tank you could then scale that amount down to how much you need to add per bucket of new water added.

If you haven't added salt previously then start off with very small amounts and gradually increase it. There should be directions on the salt container for how much should be added per litre of water. My salt suggests 1 gram per litre. So when I start up my 40L tank I put in 40g, and for water changes I put 9g into my 9L bucket.

Remember in summer when you're filling up water which has evaporated away that salt doesn't evaporate. If you're topping up the water level and not taking any water out then don't add any salt.

Mollies don't require salt, but they tend to be healthier with salt, and it brings out their colours more.

Answer 6

Beneficial bacteria is not contained in the water, it's in the filter media, gravel, decorations, etc. So do continue with your weekly water changes contrary to other opinions. I have fish in my tanks that don't tolerate salt-plecos, cory cats, and tetras so I can't give proper dosage instructions. Check on these forums for your best response to that. I've actually seen mollies in full blown salt water tanks, they looked kinda shabby though lol.

Answer 7

You shouldn't add salt directly to the tank. Mix it in the water first. We cap off the tank with distilled water all the time. Just keep track of your salinity.

Answer 8

Mollies love salt so the more the better, every time you do a water change you must add salt, about a handful with eachchange should suffice

Answer 9

You do not need to add salt. But if your fish are feeling a little down, then use 1 tsp. of salt per gallon...

Answer 10

For freshwater fish including salt is nicely maximum perfect in the process the early stages of tank biking. it is going to evade nitrite poisoning via inhibiting the fish's uptake of nitrites. it will be very stable on your fish, only see you later as you persist with the learning. There are few if any fish which will fall ill from the low a million tablespoon in keeping with 10 gallons on the learning. you may bypass to a heavy salt dose of three tablespoons in keeping with gallon whilst treating ick parasites without ill outcomes to maximum fish. once you're paranoid approximately it, you may get a salinitytesting kit from the pond component of your fish shop. Its an exceptionally consumer-friendly attempt the place a million drop of reagent = 0.01% salinity and its precise for freshwater stages. in case you shop it under 0.14% very just about something freshwater will stay, under 0.08%, maximum plant life will stay. FYI nevertheless, maximum african cichlids desire minerals like calcium and magnesium in the water (not south american / new international cichlids). Having the ideal hardness will probable bypass extra than having the main appropriate salinity for them. do a google seek on "aquarium KH" and "aquarium GH". a lot of human beings strengthen the magnesium content cloth of their aquariums at the cheap via including epson salts.
