Cycle is underway (ammonia spike measured yesterday.) I'm dosing a bit of MB-7 in the hopes of speeding things up a bit.
The Reef Brite LEDs arrived - The coloration is about what I expected (to my eye ~18K) and will be a nice base that can be fine-tuned through T5 selection - Most importantly it provides just the right amount of shimmer and added PAR. Still working on how to attach it to the T5 fixture.
The modular design of the Puzzle Rock is both a boon and a curse. Although the space is very tight for the amount of rock in the tank (less than 1/2" wall clearance in some areas) It's very easy to move and rearrange the pillars. The curse is I can't seem to leave it alone. I spent about 3 hours last night making tiny adjustments and placing base rocks. Working in the lower part of the tank is very tedious. Every rock placement and readjustment has to be done with 12" curved forceps. It's rather like a reef version of the game "Operation". The design goal is that every rock is created, selected and placed so as to appear as if it might have been there naturally (or at least as much as much as possible) and that is serves a function for the type of animal intended to be placed there (light, flow, space...)
I "think" I've finally reached a design I'm happy with. I was able to relocate all of the mechanics (heater, ORP probe, pH probe, Temp sensor, Osmolator sensor and top-off line) behind or immediately beside the skimmer. The AC20 tucks nicely beside the skimmer and is working great. 100gph of dead silent mechanical filtration that will hold enough GAC and/or GFO as needed. A pleasant surprise is that it rests perfectly on-top of one of the Tunze 6015 attachment magnets, freeing up even more space.
It's a bit hard to visualize - I'll post pics tonight.
