Ok, new question. The angels have been in the tank for almost 2 months (we started with a fishless cyclefor a few weeks then added the angels). After adding the rest of the fish over the last two weeks (which I now realize may have been too much too fast) we are having a slight spike. .25 ammonia, 0 , 5 , 7.4-7.6, temp - 80 F Tested with API kit. We are using a canister. Is this normal? We have been doing daily 25-30% changes. Using conditioner. Will the bio filter eventually catch up to the current load and how long does this usually take? Are daily water changes the best way to treat the ammonia spike or are there other methods I should be doing as well? Thank you all for your help so far! EDIT: after posting I tested my tap water and the ammonia straight from the tap is .5 Any suggestions? Should I be double dosing with prime when doing water changes?
