Maybe your RO/DI is 100gpd membrane? Or you have higher inlet pressure? You're right, with a TDS of zero .., just run with it and be happy.

I'm getting zero right now but it's all new prefilters and new DI. The RO is outputting steady at around 7. Not the best membrane I ever owned, the one before this one had a much better rejection rate or whatever the term is, it was almost always zero except for the first half hour or so. My DI lasted much longer on that membrane .. until the membrane went that is.

If it is a good and properly labled membrain ie. a Dow filmtec TW30-1812-75 it is 75GPD @ 50 PSI. at 90 PSI it should give you about 130 GPD. the max operating PSI is 300PSI on the dows and I think you can get about 170GPD out of that one @ 100 PSI

these numbers are for 75 degree water temp, so you won't get that much as I doubt your tap water is 75 degrees. for example the 75gpd membrain only puts out 50gpd at 60 degree water.

I've got lots of cukes because the donkey dungs seem to be able to reproduce in my system. Sadly, I'm too far away to help you.

"Donkey dung" = "tiger tail" cuke? If so doesn't J&L pretty much have them more or less all the time, or at least on a regular basis? I bought my last few from them, just emailed them and they had some. If you're OK with waiting a few weeks John we could pool an order maybe?

Thanks for the comments all. Tonight the tank is 2/3 full. I thought I had until maybe Thursday morning before it will start spilling over into the sump but I'm thinking it will be about this time tomorrow now. I better vacuum out the sump. Also tomorrow night if all goes well I should have a new skimmer to plumb in too. W00t w00t!!

Bittersweet update tonight in the most literal sense of the word I can think of.

First, the good news. Tonight, special delivery via BC (thanks once again Chin

you can't imagine how happy I am with this new toy!!):

Unfortunately that's not all that's happened today. At the 11th hour, ie.:

This:

So with water not 2 inches from the overflow point.. I decided before it starting spilling into the sump that it would be a good idea to pull the sump out and silicone around the stand to contain floods to the tank room in the eventuality water gets onto the floor. Ya know it's gonna happen sooner or later. The bonus for this would be that it would be easier to clean the sump outside of the stand.

So, siliconed the stand around the edges, cleaned the sump, maneuvered it back into place, and .... pop. The arrows and the dotted line show the extent of it, it goes from the top, down 2/3 of the way into the first baffle space, does a 90 degree bend and then back into the first chamber down to the bottom. Stellar maneuvering there of the sump Tony.

It had been a few weeks since I had a good swearing session over a tank build development ... trust me the streak is over. And the RO/DI shut off. In the words of Kevin Kline in "A Fish Called Wanda" - "I'm just a little *disappointed*."

Thought about patching it but .. I dunno. My old 75g had a sump that I cracked too, and I lived with a patch. It looked so ghetto. I'm going to price out an entire panel tomorrow and a patch piece and decide from there. I may just elect to replace the whole thing. Other than the silicone on the seams and baffles it would be a straightforward thing to do, it just means I have to wait though some more before I can test my return pump plumbing. ARGH!
