I've got my tank set up and running now for about 4 weeks. I used an existing established canister filter from my previous tank. I also added a 2nd canister. Now it appears I am having ammonia problems. I started with 3 fancy goldfish immediately and had no issues with ammonia. Since then I added 6 fancy goldfish in 2 weeks. 3 one week and 3 last week. It appears now I am having an ammonia spike. I read about .25ppm. I did anticipate a spike due to adding the fish so quickly so I had been doing 25% water changes every other day. So I'm on day 3 now of ammonia creeping back up to .25ppm levels. I'm suspecting i'll have to do another 25% change tonight when I get home. I expected the filter would have caught up to the extra load by now since it's been 5 days since I added in the last 3 fish. And I've not fed the fish in 2 days.
My question is, Prime says it "detoxifies ammonia" does this mean every time I change water I'm essentially taking the bacteria's food source away? In essence stalling the cycle?
FYI- this is a 75g tank with 2 sun sun canisters flowing over 750gph combined and a sponge filter rated for a 75g.
Yes I know, I have 9 fancy's in a 75g- they are small though. My intention is to remove 4 of the least attractive ones once they start to mature.
