The coppersafe killed off all the bacteria but the snails were still alive even though the ammonia was off the charts. I then added 1/2 a bottle of ammonia to try to wipe out the snails once and for all but they are still in the tank so now after a couple of weeks and several water changes the tank has been recycled . A goldfish lived for a day so I added 4 clown loaches and they've made it for another day and all is well so tomorrow I'll add the other 5 loaches , the next day the silver dollars , then the vieja , the rotkeil,and eventually the RTG arowana. As long as the water keeps testing OK. When I add the arowana I'll add 2 more AC110's so total filtration will be 2-FX 5 --- 3 AC 110's and a uv sterilyzer.
