I did some rearranging of my system and thought I'd give everyone an update. My 12 gallon nano is. alittle overkill, but I can't argue with the results. Filtration modifications: 1st stage- Surface and midlevel water input. Chaeto with JBJ fuge light. 2nd chamer. Skimmer (HOB Remora S, heater, chemipure elite (want to change to blue, 3rd chamber, 200 micron sock. Eliminates all air bubbles and cleans niceley. Need to wash every 3 days or so. 4th chamber- Return MJ1200 pumps out to my CSCX-1 chiller, then returns through the default return nozzle. Biological- Chateo, around 4 lbs of rock, and an inch or sand bed. Various snails and crabs. Bioload: clown, bi-color blenny, and a stil shy purple firefish. Tank gets cycled 30x per hour with the assistance of two hydor 850s on a hydor wavemaker set to rotate pumps every minue, More water overturned and oxidezed in Remora-S (MJ1200). I have a DIY screen on top to keep the fish inside where they belong. Now I just want more corals! ready for SPS! but only adding one animal every 2 weeks...so trying to go real slow. No more fish, just coral. Would like a pistol shrimp to pair with my blenny. He loves hiding in LR holes. So yeah, thats whats going on. Had some cyano, but gone now from lights off for 24 hrs and some red slime remover. Dosing 2 part, and would use Red Sea NoS PX4=1 if needed. The red sea nitrate/phosphate remover really helped tank algae out of my other tank, just make sure NOT TO OVERDOSE. Killed a few fish a few years back, but a good product when used as directed. Also, love my Salifert test kits!
