Well it happened that initial case of the uglies happened. I gotta say, even knowing this was coming, it doesn't make me feel good at all. Tank that was for the most part pristine white, to BAM brown "overnight"... So the time frame was far from overnight, it was over a 1 week period when I was away on vacation, part of me is happy I didn't see it happen slowly, kind of the "jumping in the pool to get the shock over with" type of vibe. But then again I'm sure the auto-feeder setup probably had a bit to do with it too, I never know which side of the fence to go on for feeding while gone, do you feed lots to make sure they're happy, do you underfeed a bit so you don't accidentally over feed, either way food feeders are notoriously random with how much food goes into the tank on any one bit.
But whatever, set up the auto feeders, realized I didn't have any sort of feeding rings, so made one myself from some scraps of that PVC foam board, and sure enough... PVC glue works on it too
1.5" pipe piece, some glue, and it was set in place nicely on the end, that edge piece was to stiffen it up a bit. Watched it in action before I left, food actually gets pulled down the tube instead of sinking, basically acting like a venturi tube when water blows across the bottom.
The 40 had a lot worse look to it, as the rocks in here weren't completely super bleached out, so some algae forming that came off easy enough with a toothbrush and siphon hose, some of it grew back (as you can see) which means I'll just clean it off again, and again until things stabilize.
The 200 was a bit more of a disappointment, there is an absolute caking of light brown stuff (not bubbly) on the rocks and sand. I did find when I put the powerhead in front of a rock it it almost blew it completely clean. So maybe sometime after this weekend I'll throw some filter socks on and scrub the rock down with a toothbrush to knock off the loose stuff and remove it. At the very least around the few frags that are in there so they don't get overgrown. But yeah need to make a decision on flow like super rapidly. Do I try to reuse my MP40s, and just buy a bunch of QD wetsides? Do I get the new Gyre? Do I do both? We'll have to see... but I do need to go quickly.
I did test the nitrate and phophate levels, like the first successful one I've ever done in 20 years of reefkeeping!
Really gotta give 2 thumbs up for the Red Sea test kits, that little "Comparitor" (color wheel) is quite nice to see your sample versus a clear reference. Nitrates were about 0.5ppm, and phophates were somewhere between 0.08 and 0.12 ppm, which may be a tad on the high side, but I'm not trying for ULNS or anything, some of that may be due to over feeding from auto-feeder while I was gone. But considering there are only 3 fish in there, it may be something I try to get under control sooner rather than later. I also realize those values may be a red herring as the rapid (diatom? algae? whatever) growth may be consuming existing stuff, so if that dies off then numbers may go through the roof.
Either way, maybe a lanthanum chloride product should be on stand by... but like I said, just waiting for things to pass before I get too worried.
Oh and a new sump is going in, more on this later, but basically what I have was always a temporary setup just to get the tank up and running. I think the quick decision on this was due to my bubble catching trap really makes it problematic to throw on filter socks when I'm cleaning... and the reality if my overflow was dialed in, I shouldn't need a bubble catching trap.
