just got a bit od a concern as far as your closed loop goes..... you donthaveany shut off valves incase of pump problems that cansee... you unhook that thing and drainyour tank... unless i just dont see it.

I think I see a check valve in each line. But I wouldn't trust a check valve either. But at least it would take a long time to drain the tank out with a leaky check valve.

I have ball valves on each outlet plus one on the drain. Those aren't check valves. They are quick disconnects. I'll snap a pic tonight.

I went a different way for the sump. Instead of one big tank I decided to go with 3 smaller ones. It allows me to isolate a certain chamber if there is an issue or if I want to change something later.

Got my RO system up and running. Filling sump as we speak.

QUESTION:

A local aquarium builder told me it would be better to fill in the section under the drop off completely with sand, worms, and crabs and make a deep sand bed as opposed to filling it with some rocks and running a pump in there to circulate water.

Opinions?

In other words fill in this section with deep sand (imagine a piece of glass across the top):

Adjusted overflow and hung two lights so far.

Gonna start aquascaping soon.

3 feet to stare into on-end that's going to be RAD. The end view is hands down my fav and with that ehight it's really going to have an amazing presence.

How many SOL in total? Looks to be 3 but won't that be on the low side for coverage?

I have 4 eshine systems 3 watt CREE LED units. 2 are still on my current 120 gallon.

Gonna transition coral and rock over very slowly to avoid any die off.

read through this build last night, very nice! That is an awesome idea for a room divider! The only thing I don't like about this build at this point is the fact that there's no fish in the tank yet.

Hahaha. Soon. Just want it to cycle properly and build up a good amount of bacteria. Already have crabs in there.
