I'm converting my 75G FOWLR
to a reef, slowly. I have about 40 pounds of LR
that have been in my tank for a couple years or more. I swapped out my CC
substrate with a 2" sand bed this weekend. I mixed in 20# of LS
with about 40# of Aragonite sand, and also kept 2 small football sized stocking balls of my old substrate to seed the new sand. I will soon be adding an additional 10# of LR
that I am curing now. Tested the water this morning (48 hours post-swap) and everything looks fine. Fish (3" yellow tang, 3" purple tang, and a 1.5" Scott's damsel) are doing well. I'll be doing a 15G water change this evening, just because it's time. I'm still running a large wet/dry trickle with a skimmer and a sump. I want to go ECO, but that's later.
My problem is lighting. Eventually, I want to go with 4x65w PC
's. Custom Sea Life has a cool hood with moonlights I want, that I can get for about $270. That being said, I am going to have to stretch what I have for a month or two until I can purchase this new hood.
The fish were fine under a 48" 40w 20,000k single bulb fixture. I added a 36" 2x36w fixture with a 10,000k and 03
Actinic that I had on a previous tank, and the tank looks a lot better. Is this going to be enough light to prompt some coralline growth on the new LR
? I'm not going to add any corals for a few months or so, just a cleaning crew and more LR
. I want to end up with about 110# or so of LR
