thanks for the calculater, that helps. At ph 7.4 and temp 78-79, it says my NH3 level is 0.06 ppm so I guess its borderline. I have noticed that my harlequin rasboras do seem more sensitive then my other fish. I had some overnighted to me, a couple were DOA (they were handled roughly during delivery- juggled actually) , but the others became lethargic, quit swimming and died off over several weeks. I bought some from LFS and Im seeing same behaviors, but if I do an extra waterchange with primed tap H20 or simply just add prime to their water they become active again and even start spawning. I havent lost any and its been months now. I gravel vac every 5-7 days, feed just once a day and food disappears with in a minute. I am probably overfeeding in the 32 G as I just added kuhli loaches Im unsure about how much to feed them. I feed them at night before I go to work, so I dont get to see how much they are actually eating. The snails are eating a lot of their food. Im hoping the loaches will eventually get the snail population under controll.

No matter what I try my ammonia levels in 3 planted flex aquariums (two 15 G and a 32G) stay at .25, Is this harming my fish? I dont get ammonia spikes just a constant .25using API master test kit. Even when cycling I rarely had 0, mostly 0.25. PH in all 3 tanks is constant 7.4. with crushed coral in all 3. Nitrites 0, Nitrates 5. There is 0.5 ammonia in my tap water which isnt helping but it seems adding extra bacteria would fix that but it hasnt. Ive tried new and old bottles of both Seachem and Fritz products, a faucet filter. There isnt room for under sink or whole house filtration. Would adding Purigen to my sponge filters help? Any thing else I should try?
