May I ask you a question? I just saw you are using two white plastic buckets for your skimmer and as a sump. What are they actually? And how big are they?

Thanks!

The skimmer is a G6. It may be cheap, but I wouldn't call it a plastic bucket!

There are two sumps. Both are PE plastic. I purchased these from a tank manufacturer and they were shipped from Florida. The larger one is 120 gallons (48Lx24Wx24H)...the smaller is 60 gallons (36Lx20Wx20H). The same shipment also brought the 50 gallon mixer and the 100 gallon RO cylindrical tanks.

I would have been nice to do the sumps out of acrylic, but there was just too much money to be saved doing them in PE since I had to purchase/ship the cylindrical tanks no matter what.

Here's a shot of the RO/DI system. It is plumbed directly into the water supply. RO/DI water is collected in the upper 100 gallon tank. RO/DI is float valve controlled to keep this tank full at all times.

The blue line running down into the sink is temporary. That line will eventually be plumbed directly into the drain. Theres also an emergency overflow pipe coming into the sink on the right. That overflow pipe comes from the top of the 100 gallon holding tank and is there in case the float valve fails to stop the RO system.

You can just see the blue 1/4" line that leaves the RO tank on the bottom-left. That runs over to the main sump and delivers water for evaporative control (gravity fed, float & solenoid controlled). This line will also feed a Kalk reactor.

Beneath the 100 gallon FW tank is the the SW mixer tank. This tank rolls on casters and can be pulled out from underneath when I need to mix SW. The mixer has a Mag 1200 pump that will be used to mix, then deliver the SW.
