Hey guys! Sorry for not posting in a long time but tonight I got a chance to go check out this trainwreck of a tank in person (just kidding). Mike wanted me to post all my terrible criticisms of his tank but honestly there weren't many at all.
We took out a few dead monti cap pieces from the display but relocated them to the refugium (they make great grow out rocks for soft corals as they're easy to break into pieces) to clean up the tanks looks slightly. And wow, I've got to stress for Mike again that these were far from frags, they were colonies of montipora. I did see some great growth from alot of his stuff and overall everything looked happy.
That being said, PH seems to be the sand clumping problem's cause. Mike runs a relatively high PH of 8.4 with all the kalk he doses and I imagine this is the cause of these clumps of sand. And when he said "clumps of sand" he meant it. They were literally little rocks of compacted sand, already being covered in coralline algae.
The other thing that I've never liked about his tank was his lightbulb choice, an XM 15k bulb. At the time, this was the new bulb on the market and was a very very promising bulb. However, I'd never ever recommend one now, this same situation occuring with my original bulb a giesseman 20k. If any of you have never been to Sanjay Joshi's site comparing halide bulbs, I strongly recommend it ( http://www.reeflightinginfo.arvixe.com/). So while I was there I decided to check his results for this bulb. We'll put it into perspective and compare it to the new hot bulb on the market (of which I'm currently using their new DE version with great results) the Coralvue Reeflux 10k. The XM bulb had a relatively low energy output at only 45 PPFD while the Coralvue bulb put out 113 PPFD. The XM bulb also had no real spikes at any wavelength and just flatlined. While the comparable Coralvue bulb had spikes at 410, 450, 540, 590, and 670 nm.
The comparable Phoenix 14k bulb had a PPFD of 88 and several spikes most notably a huge one at 450 nm. This is the bulb that Mike will be switching to shortly
.
Mike's tank is looking great really though! Coralline algae has exploded all over the tank and the live rock looks incredible. Most people would probably be happy with their current XM bulb and I'd say that Mike's softies (especially his blastos) love it. The SPS and monti caps though show some polyp extension but I'd like to see more, and I believe this is directly linked to his PH and lighting which will be fixed in a snap.
Mike has a great tank and has made me decide that I really really need the new reefkeeper 2! I also forgot to tell you Mike that I think Salifert test kits have something like a year shelf life.
