RO System Recommendation

Recommended Posts

perk73   

So, want to install an RO systems for water changes and got to thinking.....why not install one that is dual purposed.

The below RO system can be installed under the kitchen to provide clean water....for drinking, would this also not be good clean RO water for water changes as well?

I question how often the filter would have to changed though.

That is just an RO filter which will definitely help but most of use DI as well to bring the tds all the way to zero. I don't know the quality of the membrane that is included with that unit but even the ones we use only take out 85 to 95% of the tds depending on the set up and the amount in the source water.
I know that air water ice and a couple others have units that have the under sink reservoirs as well as the DI. You might save money in the long run buying a better unit up front then trying to dr up one that was designed for drinking water.

Yep.  If you put your RO anywhere near your sink you can always add a pressurized tank and run a line in to an RO faucet. The tank would just hook up between the RO and DI, then with a check valve to prevent it emptying the tank through the DI instead of only the faucet.  We don't use it for drinking, but I ran a faucet just to have a handy spot to rinse frozen food, test vials, or any other small need.

I just built a filter for my sink. I used two standard cartridge holders and put a micron(cannot remember what size) then a carbon block for drinking water. And water flows through so no need for reservoir and I have it hooked to a spigot like in above pictures just for drinking water.

I would get the BRS 4 stage plus if you don't have chloramines or the 6 stage for all around better water. Then just purchase the drinking water kit from BRS to add to it.

I would not buy a system from Lowes. Their filters are not made well like BRS. BRS carbon blocks are heavy and have much more carbon for less$$, also the sediment filters are better and you really need a DI stage for reef tanks.

I have a BRS 6 stage water saver plus, all upgraded from the 4 stage and so glad I did because I make water 2x fast with 1/2 the waste water and get more product water from every filter.

Well, the whole purpose is a "good enough" system, small foot print to keep outta sight.

I think Marine Depot sells a RO/DI unit called a Buddy or something like that,  it all folds up into a tight triangle shape that looks like it would fit under a kitchen cabinet well.

Water quality is kind of a big deal in our tanks so any of the unknown variables we can eliminate by filtering the water better the better off we are in the long run.  More than likely what will make it through the RO membrane will be Phosphates which leads to algae farms (in most cases) in our tanks if its not managed well.
