Reverse osmosis filters?

R\O filters work like this: One hose connects to your tap (sink), screw in, if none have then need to connect outside. then 3 other tubes, 3 different colors, 1 is for bad water, 2 other is for good. You need to have the 2 good tubes empty into a bucket, contanier, something and the bad water expel down the sink or on the lawn. Now the prices work like this, the higher the price, the more gallons per day it can produce. So if you have alot of tanks and do alot of water changes you would want more GPH, I have a 25 or 35 GPH R\O and its fine for my 55 gallon, 30 gallon, and 90 gallon, I just do water changes different days for each. You can probly go as high as 250 gallon per day, but thats alot of money. 35 GPH R\O should cost about 120-150 dollars. This is the best filtration possible. It strips your water of 94-98% contaminants and minerals. Basically straight h2o. You buy R\O Right which is a jar of powder containing the natural minerals back into the water, the more you add the higher the pH. The R\O filter will bring the pH down to 4 or 5. Add the R\O mix as necassry to achieve your pH. it will come with instructions. This is what serious aquarists use. But don't be fooled it really not complicated to use, just let the water flow thru and gather the good.


EDIT: buy from Big Als Online, they have the absolute best prices, garaunteed. Direct Link to R\O Filters

Hi, I'm new here but thought I would post my 2 cents worth.

I have a 5 Stage 70 GPD RO System that includes a booster pump (our water pressure is pretty low). I got it from Natures Beverage via internet. You can find it here. It still costs the same $242.95 that I paid 2 years ago.

They even send out yearly reminders/order forms for replacing your filters when the time comes.

I use this for my Betta Barracks and any additional tanks that I have set up. I use the R/O Right as well but use the liquid form as I don't really care for the powder version. I get that from Drs. Foster and Smith.

Hope it helps.

Ro units do not have two tubes for product water, they have one.

There is an inlet from any high pressure line in your house, then two outputs, one waste the other product. There is always significantly more waste than product, usually on the order of 3:1 or higher.

naa sorry mine has 3 tubes for expulsion and 1 tube for incoming. Havent used it in years though since my pH is exactly what Malaiwi cichlids like.

RO units dont have multiple product water lines. It would make it very difficult to shut off the unit with any of the RO float valves.

Maybe you are looking at different types of units, but none of the aquarium units have 3 lines, nor do any of the home RO units Ive seen around here. I do not see the benefit of an additional line of waste or product water.
