Project II : 20L with 10g sump & 10g frag

[xxlbreed]

Im back with another project. I am currently in the planning of a 20gallon long display tank with two ten gallon tanks attached to it in a cycle. A 10g frag tank and a 10g sump. This is going to be a budget build but a great one.

I am currently working on the live rock (&frag plugs), i am making my own diy live rock out of oyster shells, portland I&II cement (gray) and rocksalt. Still trying to get the mix right.

I will also be making my own stand and setup.

Most of the stuff I already have from my 10 gallon build which is doing amazing! Planning on just moving it all to the 20 gallon setup in a couple of months without adding live stuff - so no "live" sand and no extra live rock, only my diy rock - so i am hoping nothing will cycle. what do you guys think?

Here is a quick sketch of the setup i am planning

Current to do list:
- electronics setup (arduino reef control)
- 20L tank (waiting for petco sale)
- plumbing starting soon
- aqualifter to keep siphon going
- lights (mentioned above)
- Sand (already have live sand to seed. buying dry sand.)
- finish diy live rock (still working on the right mixture ...)
- plexiglass for sump
- diy stand using cinder block and 2x4s
- reef crystals from now on no more coralife crap ...

im going to keep my aquatic life 115 protein skimmer - it works miracles for me.
trying to get all the funds together for this new build.

you guys think one aqualifter plumbed to two 3/4 inch pvc overflows will do it?
anyone with experience on this?
