Have had 10 gallon going for about 4 months, and am getting new 55 gallon going. I have 1 male betta, 2 rosy tetra, 2 plati, and 1 guppy running on whisper 10 filter that has been working surprisingly well. Will be running to aquaclear 60 hob's on 55 gallon when completely cycled. Here's my plan on tne transition. running the whisper 10 and from cycled 10 gallon, and 1 aquaclear 60 on the 55 gallon, along with large piece fake driftwood and all other decorations, fake plants etc from established 10 gallon. what I would like to do immediately is add the stock I have in 10 gallon along with bottle of 75 gallon tetra safe start to the 55 gallon as I don't have enough room to run both tanks. I had success with tss in 10 gallon, what do you guys think, good or bad idea?..?
