I'm carefully planning my next tank(the 75g), I plan to have various Tetras, Corys, and Rams...so basically I want soft water! I plan to add the Discus Buffer(Seachem) to keep my pH between 5.8-6.8, will this work? How much gpd do I need? Does anyone know a really cheap R/O unit?

:arrow: I found the Kent Marine Bare Bones Unit (TFC 10 gpd) for a $100?

Raul 7,

Not entirely sure why you want to run the soft water. IME I keep tetras and Ram's in my tank and have a GH of 6 to 7 and a KH of 7 to 8 and they all do fine in the tank...the Rams spawn every 8 days or so.

2La....any thoughts?

KH is alkalinity right? GH is soft/hardness. The barebones is good if you don't mind leaving it overnight to fill up 5 gallons. Have you looked into adding peat moss? I am going to start to make a peat moss liquid that I can add to the tank to lower GH. Use the peat moss like tea bags to make the water. Kent marine has a product that is similar, but only adds the tannins to the water.

Also consider the impact a RO unit will have on your water bill. Normally for every gallon of water you get out of one you can expect three or more gallons to go down the drain.

I slightly agree with Rex although I use RO. In order to not make the wastewater be exactly "waste", I direct it to my yard and flowerbeds. When I had an african tank, I used the waste water to do water changes.

I'll echo this too. My water is 8-9 dKH and 9-10 dGH and I keep Rams AND Chocolate Gourami's. The Rams breed and the eggs hatch. Plants love hard water so I've never understood why people want R/O water unless it's for Discus...though I'll kept Discus in this water too.

I don't know that my input would be any more helpful than that of anybody else's, but I guess the first thing I'd like to know is what the starting water parameters are fresh out of the tap?
