I've got a fairly new 100 gpd unit from Aquasafe and all I get is 30-35 gpd. Took forever to fill my tank initially. The 100 gpd is a myth to sell the unit IMO, unless someone else out there has made the unit go into top gear, I would like to know how. Just my 2 cents worth.

i have an older marine depot 4 stage unit. it can fill my 30 gallon brute can in around 5-6 hours. when the carbon prefilter is shot it takes around a week to fill the container.

The manufacturer doesn't tell you what temperture you should have but does say you need at least 45psi. I did put some of the hose in my sump to help warm up the water and it did help, last night in 8hrs I got 12gals which equals out to 36gpd, thats up from 17hrs and 11gals. Tomorrow I will post temperature & TDS going into R/O and temperture & TDS coming out of unit.

My instructions do mention that lower water temp will slow RO productions and increase waste water as well. I think DanG has something there. By increasing the legnth of the 1/4" inlet line and coiling it up and submerging it into your sump or a bucket of heater water would be a good way to temper your water supply. It shouldnt take much energy to temper water in 1/4" tubing. I think Im going try making myself a simple flow through heat exchanger.

I get about 200 gpd from my unit this time of year, in the summer about 280 gpd.
One thing to note that a 100 gpd unit might realy be a 65 gpd at 60 PSI, most membrains ate dual rated ie. 65gpd@60 psi/100gpd@90 psi. My membrains are 90GPD@60PSI/160GPD@90PSI. so if you are running them at 55 PSI you are going to be even lower than the 65 GPD and then cold water is a huge difference as they are usaly rated at warmer water also.

b_james,
Could you please do me a favour and test ammonia levels of the water that comes directly out of your RO/DI unit for me? I'm getting .5 ppm ammonia out of my unit. Here's my thread on this issue.... http://www.canreef.com/vbulletin/sho...136#post186136 TIA
