RO/DI - Please tell me I did good!

Ok...

I just bought it (150gpd version)... please tell me I did good.

I have read on these boards that the 75 gph membrane has the highest rejection rate. If you are interested in more information about the best RO/DI units, there are several excellent threads if you use the search button at the top of the page.

Good advice, if the search button ever worked.

The BFS units are great.

[bsagecko]

i just went through the same thing....only i have decided to go with thefilterguys.........

the 75 gpd membrane is alot better due to rejection rate but BFS is suppose to be a good company and a good product.........(they just never answered my emails so i decided to go with thefilterguys instead)

but definately a good product from what i have read.......

Though I do not have a BFS unit, I use their 150gpd RO membrane. It makes 180gpd at 99% rejection rate. PLEASE keep in mind that I am using a pressure pump in conjunction with this in order for it to work properly. My system runs at 85psi.

[FranktheTankTx]

Thanks Old Salty.

Yes, I talked to Russ at BFS today about the 150gpd unit. He mentioned that this unit is only effective if you have 60+psi water pressure. Fortunately, after measuring mine... we have 80psi at home. So this unit should work wonderfully!

I'm really excited about this!

Don't leave it on. The flood from a 150GPD RO is pretty nasty. Awesome water pressure!

Yea, I plan on manually filling my ATO resorvoir which is 17g. A 17g reservoir will last my 36g corner at least 2 weeks.

Question... do you need to keep your reservoir flowing with a power head? Or can RO water just sit?

[old salty]

I'm not sure it really matters. I mix the salt in as soon as I can just in case there is an emergency (which is less likely to happen when you are somewhat prepared.) I would probably throw in a powerhead; couldn't hurt. I just made some drinking water a few minutes ago. TDS was 1.7ppm from the RO output. Makes the DI filter last a long, long, long, long, long, long time.

[FranktheTankTx]

Just to make sure we are on the same page... I was speaking of my 17g reservoir of fresh RO water. I plan on filling it full and then letting it ATO my sump's return section.

I don't remember hearing that you need fresh RO water to be circulated in your reservoir. But I could add a maxi jet for some circulation if it would help.

I'm not speaking of water change salt water. Just the RO water in the ATO reservoir.

[snorvich]

I don't recirculate my top off water (a 4 gallon reservoir which is autofilled, one per tank) but I do recirculate and heat my salt water reservoir which is 250 gallons.

[old salty]

OK, I understand now. Usually the ATO water is also deionized (DI) and that is usually how it is referred. In that case, I do not stir or agitate the top off (44g Brute.) I keep it covered to prevent dust from getting in the water.

Thanks!

Heard really good things about that company
