No unions on your drain for cleaning?

No, no unions.

Should I have some?

What you've done is by no means wrong, just a personal preference.

If it were me, I would have each flex going into a union, one above the elbow on the right, and one above the branch of the tee. This allows you to completely remove the drain rail for servicing and/or removal the sump.

Like I said, it's a personal preference.

Aquascape - testing
 

So last night after I plumbed everything I started playing with my rocks.

I know about the rules of 3rds... from reading lot's about photography.

I moved the rocks around all night...
Here's a few shots of what I did... and ended up with.

I'm going to Epoxy the rocks together... Is there a better solution for this?

This is my prefered layout

Going to be making a mount for my lights, want to install this before I put water in the system. #waitinggame #killingme

Update
 

More progress!!!

Making a custom mount for my lights tonight AI SOLS.. Going to hang them tonight.

Then the FUN PART #waterhitsthetank #prayfornoleaks

What height do you hang your LEDS above the tanks? I was thinking 8"

I would go 12 inches. You will get a better spead. Also I had an AI sol super blue on my 18 x 18 and it was loads of power. This will help you keep the light up in tiny tank without scorching all your corals. Nice build. Looking forward to seeing water in it.

That's alot of sand in a small system. Gonna take alot of vacuuming!

Vacuuming?

I never vacuumed in my previous reef (90gls).

I thought you weren't supposed to disturb the sand bed (substrate)

It's got water
 

So, time for an update. :)

Quite the weekend. Filled my system up on the weekend, it's always an adventure to see your project progress.:biggrin:

Turns out the small system failed...and leaked. My external overflow had a leak and the seems. After some messing around to fix it. I damaged the tank and cracked the bottom panel. So off to the recycling with it.

I took advantage of the situation and had a custom one build with larger dimensions to fill the shelf properly. Looks much better!

Also I wasn't running a filter sock on my overflow and my skimmer pump Sicce Syncra Sk400 sucked in some debris and broke it's impeller shaft.

I can't manage to get the magnet out of the body and don't want to damage it further.

Does anybody know how i would go about this? Getting the magnet out? Needle nose pliers?
Please see attached pick.
