am i suppose to do a Large water change if my ammonia and nitrite level both reached zero??

Question

(nitrogen cycle)



show u do a 50% - 80% water change?

because i been following these steps from the website below and it tells me to do that in the end

http://www.aquahobby.com/articles/e_fishless.php

Will it mess up the ammonia and nitrite level?!!?!? <( i really wanna know that question)

Answer 1

I would not do a change any larger than 50%. A larger change might be OK. The recommendation for a larger change might be to remove the other chemicals involved in fish-less cycling. I would certainly not do more than 50%. Even a larger change will not harm the nitrifying bacteria as long as the water is de-chlorinated before adding it to the tank,and the water must be the same temperature as the water in the tank.(Or at least very close) Congratulations on completing a tank cycle without harming any fish. You are to be commended. Best of luck to you.-----PeeTee

Answer 2

NO you do not need to do a large water change when the ammonia and nitrites are both 0. I will also caution you against listening to one webpage's advice. Personally that is one of the worse descriptions of fishless cycling I have read.

Once your ammonia and nitrites and nitrates are in permissiable levels, your tank is cycled and ready for fish. Remember not to add too many fish at once and allow atleast a week or two between additions.

A regular 25% weekly water change is your best bet.

Again, be careful what webpages you get information from. I have seen some really bad ones with really bad or incomplete information.

Feel free to email me if you are still having problems.

Answer 3

I don't mean to sound rude but it seems you misunderstood the article. The article refered to fishless cycling of an aquarium. The point of doing a 50-80% water change in the context of the article is to determine whether your fishless tank is cycled or not. They were adding ammonia by themselves to the tank rather than waiting for a fish to produce ammonia naturally in an uncycled tank. If you do that big of a water change and the readings are 0 for both Amonia and Nitrite then you know your tank is cycled. 0 ammonia and nitrite are good in an established aquarium or if you were trying the fishless cycle mentioned in the article.

If you didn't actually misunderstand the article and were trying their fishless cycling method, then the good bacteria from a cycled tank should still be in the aquarium after the 50-80% water change.

Answer 4

i'm no longer precisely useful whether it sounds like the readings you may get once you only have been given carried out cycling your tank or are just about carried out cycling your tank. i could do a large water substitute to get the nitrate at a secure point. perhaps 40 5% of the water. and then try PH and Nitrate back the following day. EDIT: Do you employ a water conditioner this may be the reason to. in case you do no longer you're leaving injury finished chemical ingredients interior the water on your fish. there is a few thing observed as PH plus which you additionally can upload on your tank. Doing massive water ameliorations gets the nitrate down then including PH plus if the PH did no longer bypass back up.

Answer 5

I would recommend doing a 30% water change. Anything higher then that puts fish at risk because the water will change to quickly and the fish will not have time to adapt to it. You should do 30% now, and in two weeks, do another 30% change, if your ammonia levels and nitrate levels are not where you want them, take your water to a specialty fish store, not like pet supermarket, have them test your water, and they will tell you what you need to do from there.

Answer 6

I wouldn't do an 80% change but yes a 50% water change at the end of a cycle gets the nitrates under control and sets things up to add fish. Changing out a large volume of water at this stage will not hurt anything and will only be beneficial. The bacteria lives primarily in the gravel and filter media. Make sure your pH and temps are good then you should be able to add in a few fish. I read the article and it is a very good one. Fishless cycling is the only way to go and I'm glad to see someone doing their research before starting up a tank.

Answer 7

No. Do a 30% max!! And then 20-30% for weekly water changes

Answer 8

no amonia is great isnt it? change quarter of your water every week and keeping track of ph and water chemistry through out till better

Answer 9

Well, yes, because all that stuff in their has been lying their for six weeks.
