Medication killed my bacteria and I am in cycle mode. Ammonia is 2. No nitrites or nitrates. Have been using AP water conditioner & ammo lock during water changes every day. Tetra cycle (-new name for bio-spira freshwater) has been ordered, on the way. Have 8 cichlids in a 55 gal. and one pleco. I have placed old filter material and some gravel from my 30 gal into it. Will the ammo-lock have any effect on the bio-spira???? Tried this same thing last week. I was using Prime-found out the Prime killed the bacteria! Other than water changes. what can I do??? Thanks
