Well I am trying to figure out why my apisto got dropsy, I did some water tests. My ph from my tap, which is what i use for my tanks, reads 7.0-7.2 My tanks read 6.6-6.8. The one tank is bare bottom, with 1 apisto mom and 20 fry. I feed babe brine, cleaany debris on the bottom daily. I alos do a 10% water change every day, which is one gallon. The power filter carbon has been replaced about 1 week ago. My 30g planted tank is about the same ph. I do 10 gallons of water change per week on that one, usually 5 gallons every Wednesday and Saturday. Now that does have a clay substrate with 3 inchs of gravel on top, but i dunno if thats why its maybe acidic. Now I can see the plant tank being acidic as I do DIY Co2, but not the fry tank. Anyone have any idea why my tap is 7.0+ and my tanks are 6.6+. Oh well just asking some questions. Thanks. Also, anyone have plans for a rack system?? +---------------------------+ | Michael W.
