how long did it take you guys to put water in your reef tank?
i have about 220 gallons total and have been running the ro/di for 6 days now. i got the ro/di from ebay and its suppose to be 85 gallons a day. boy lied to again:(
well only 40 more gallons to go.

My Kent 60GPD does at least 60GPD. Still took several days to fill my 180 because I was afraid to leave it running overnight and while at work.

Just imagine those with a 10GPD unit...

Whats your incoming water pressure. That might be why its taking so long.

i dont know but the outlet side to the sink is a good stream.
i would die if i had a 10gpd.

FWIW, I've never heard of an 85 GPD RO membrane. Dow manufactures most of the RO membranes used in our market. They make 50, 75 and 100 GPD (there's other sizes larger and smaller too), there is no 85.

But, I'd check 3 things first. Your water pressure into the unit, the temperature of the water into your unit and compare how much waste water is being made versus product water over a 1 hour period.

Patience young grasshopper...


100gpd unit making more like 40gpd filled my 300 in a little over a week.

It was like "Look honey! there's another inch of water in there since last night!"

My suggestions:

1. get a pump to crank up the pressure.
2. get an adjustable flow restricture to get a 1:3 ratio between the waste and product lines.
3. get a pressure gauge
4. get a flush kit
5. get a 100 gpd membrane.

You'll get about 130 gapd out of it

Any idea where to get one of these guys?

That is who I meant originally. Sorry I got you the wrong address.
Thanks nathanncnm for putting the right one.
