I've finally decided to pull the plug on my 29 gallon planted freshwater tank at work, I'm tired of fighting algae all the time. Thus begins the evolution to a 29 gallon reef tank. Here's what I'm proposing so far, equipment-wise. I'm planning on keeping mainly SPS/LPS, and maybe some zoas. Fish will be limited to probably some green chromis, and maybe a clown. I'm also planning on adding a cleaner shrimp or two.
29 gallon Oceanic tank with a corner overflow with dual 1" durso drains through the rear glass
20 gallon long tank for a sump, divided into a skimmer area, refugium, and return area
AquaC EV-120 skimmer powered by a Mag5
SunPod HQI Metal Halide 30 inch w/ 250W HQI Bulb
Stealth Heater
Mag7 (420 gph @ 5' head) for a return plumbed with a scwd
2 Hydor Koralia2 powerheads
Eheim 2213 (that I already have) for phosban/carbon
Auto top-off, sump mounted
Kalkwasser drip
Tropic-Marin salt
approx. 40# live rock, with a 1" aragonite sand bed
The only questions I really have is if the mag7 is the appropriate size for the return (big enough for flow, but small enough to not push water too fast through the sump) and are the koralia2s the appropriate size for flow inside the tank. I'd also be interested in any advice y'all would like to give.
