because i have gotten some bad advice from my LFS I am doing a fish in cycle. it has been a couple weeks now and so far ok i think. my question is every 2 or 3 days i've been doing a 25 to 35 percent PWC due to my ammonia levels getting into the stress or harmful levels. my question is since i am doing frequent PWC does that slow down the cycling process? I have 2 serpae tetras and so far they seem ok. also, should i be feeding them twice a day? they eat well but i'm afraid it is leaving too much uneaten food in the bottom. thanks in advance for any advice.
