I need help and advice on how to successfully move fifteen tanks with soft, acidic water. This is my set up: I started with a 30 gal tank and cycled it normally. The water where I live now is off a well. The water parameters are liquid rock and a ph of 7,6. However, I decided to raise apistos. I put peat in the filter. Once the ph dropped to 5,5, I removed the peat and use two sponges in the Aquaclear 150. Ever since then, I have been doing partial water changes with pure steamed distilled water. My water parameters in the tanks are all a stable ph of 5,0 and a hardness of 70ppm. I have seeded the other 14 tanks from the 30 gal whenever I did my weekly water change. Thus, no cycling. I am planning a move and searching for the house with the perfect room for the fishroom. I plan to increase the number of tanks to 25 or 30. However, I am in a quandry as to how to maintain this water quality without hauling 40 or 50 bottles of water each week. Is this where you suggest a RO system? I know the principle of how it works, but I am at a loss on what size system I would need, where to set it up, how to set it up. I trust the apisto people to tell me about this moreso than the lfs guy I deal with. Sorry for being long winded, but I keep mulling over this and can't decide what to do. Thanks........
