Achillez Nano tank

Hello, I have a 20gal long. I have done a few mods to it to make it a more stable tank, the plan is to make it a sps tank.

The plan for this tank will be a sps domanited with collector zoas. so to start i
I drilled two drain holes in the glass, one being a full siphon and the other being a modified Durso Standpipes
here it is all installed


too make the flow my random I drilled two holes and installed a squid 3/4in



Here is what it looks like installed.


now for the sump/refugium!!!
it is a 36x12x12 sump modified into a refugium style sump.
