Thanks for the compliment Bayliner. The reason you didn't see it for a while is it only lasted at the front page for a couple days in Nov and then didn't resurface until just a couple weeks ago. That whole time the tank was sitting in my driveway or on the stand empty. I have been giving updates now and then for the last few weeks.
Yes I did plumb a 1" bulkhead in the top of the sump that goes directly to a drain. For now it is just set up that way, but the guy that did the water syster for the house has a product that I will probably use that shuts off the R.O. when the water level gets too high. Even if it flooded out the tank with RO that would be better in the customers eye than having water all over the house...especially when the house costs that much. Knock on wood, I have never had an RO stick on. Even if it did it would be alot cheaper to replace the livestock than repace the wood floors, carpet and damaged drywall. I do place the health of the animals as a top priority so I will be placing a shut-off on this system. I have only one other tank with an RO directly attached to a float and it will get an auto shut off as well.
I am going to Hawaii next week. When I get back I will post some pics with the rock and sand in it. It should be pretty fun to aquascape this tank.
