So, for the last week or so, the RO/DI system has been churning out RO/DI water, I've been mixing it with salt in the mixing tank, and then storing it in the NSW tank. So far, I've got ~70 gallons of pure RO/DI water and 290 gallons of NSW water ready to go. That's a total of ~360 gallons, and my RO/DI meter started to say it was reading 1ppm on the output.

Now this is a dual-stage DI-resin system, so there are two, not one, media chambers full of DI resin. I'm thinking that ~360...

Ok, so nothing major happening until Tuesday/Wednesday/Thursday when the deliveries arrive, but figured I'd clean up some loose ends...

The outlets from the media filters (GFO and Carbon) are from 1/2" RO/DI-type pipe, and have a lot of curve in them due to being shipped in a coil from BRS. I wanted these to dump directly into the sump immediately below the media-filters themselves, so yesterday I cut off some small slivers of 1" piping, and superglued them to the inside...

Well, maybe not porn - this is a pretty simple setup, so let's call it a '15 certificate'

As mentioned, I'm waiting for some elbows and adapters to finish off the below-sump plumbing, but here's a look at where it stands right now:

If it's not clear, there are 3 horizontal pipes on the left-hand side, the...

I'm waiting around for an online order to come in so I can actually finish the plumbing, so I thought I'd put in the media chambers (for carbon and GFO). This is the first use of the manifold

The center-brace just overhangs the sump, so the plan was to mount the media containers on the center-brace, drill a hole through...

So, a bit of work on the sump-side of things. Glad I'm not crawling around on my belly under the house any more! I painted the inside of the sump (including the doors) with several coats of gloss exterior wood paint. Spilling some water onto the surface resulted in a gratifying beading of the water The white colour will help with seeing what's going on in the sump when the only light down there is a refugium light, as well...

One of the design principles of the tank is for it to...
