Lots of questions, let me see:
1. running purigen for about 8 months. BUT took it out yesterday and added Seachem DeNitrate to the reactor instead.
2. Been dosing vodka now for about 2 months. The total system volume is approximately 80 gallons of water less the rock and the sump volume.
3. I didn't think it mattered. I was running phosphate and carbon in the same reactor before Vodka and never took it out.
4. No fuge and that is the primary reson for a current project to relocate the sump to the basement. I also have a 210 gallon tank waiting in the wings to go into the same room. I eventually want to put both tanks on one big sump with a fuge.
5. The tank lighting consists of 2x 250w Halide's 20k. They are on from 0900 to 1900. I also have two T5 act's which are one from 0600 to 2100. LED's are on from 2100 to midnight. Lights out from midnight to 0600. Same lighting schedule for over 6 months.
6. I have carbon in the reactor, new yesterday, and a large carbon bag in the sump, new 2 weeks ago.
7. I dose A/B every other day. I run a Ca reactor that has a 9:1 mixture of argonite and NeoMag. I maintain Ca and Mg levels typically at 460 - 480 and Mg around 1300. I also use Koral Color twice a week, 3ml as prescribed.
8. Makeup water RO with Kalk and RO without Kalk; Due to weather issues I might loose more water than I want to add with Kalk so I makeup 50/50
9. No leather's near the corals. Opposite sides of tank.
I am going to suspend Vodka Dosing.
