Thanks ABz
Yikes Mark, random RTN is scary as heck! Aside from those two though your tank is looking spot on.
Thanks Mindy, nice to see you around.
So let's go through an update. The Lokani refuses to die. I fragged off dead pieces and placed it on top of the dead SSC and I swear it 'caught' RTN and lost another 3 branches, then stabilized. Regardless, it's no longer allowed out of the water, even for 15 seconds to trim a branch. It's back in the back, and this is a bad picture.
Let's see, I got some gumption for about 6 hours to work on the tank and got the following done. I really do have fun when messing with the tank, but it's done better without me armpit deep in it.
Removed any dead corals I was not going to use as a base, plus removed 3 rocks covered in Xenia. Such a nice smell.
Hand pulled another bucket worth of Xenia off back wall. Most is being shaded now and some of the stalks were huge and easy to pull off the rocks.
Scooched the scape back to make more room in the front for flow and light to save a few corals I care about that were getting shaded.
Finally hooked the older MP40 back up with the brand new basket. The old noisy motors are much faster than the quiet drives, this thing moves some water and was probably one of the reasons I had flow issues. The giant Tunze produces more flow on paper but not so much when in the water. I moved it to the back and have it alternating on and off to provide some extra turbulence.
Replaced the T5's, same bulb combo, the Big Ed special, 2 coral+, 2 blue+.
PAR was similar, a little higher (bulbs 14 months old) but boy was it visibly brighter. I suspect they lost some of the green spectra. Raised the fixture 2 inches to compensate.
The tank has been overheating a bit (I alarm at 81, tank reaching 81.5 a few times in this hot weather). My sump fan was on but no air that I could feel. Might have been the metric ton of dust collecting in the grills. Cleaned, and decided to run without a front cover since I could not cut my fingers on the plastic blades.
Tanks temp plummeted to the normal 79F in 2 hours. Maintenance, who needs it!
I looked at the box containing the new heater I bought a year ago. Nope, maybe this winter. My intent was to install a backup in case the main heater failed.
KH right at 7.0, a rarity for this tank.
NO3 is 5, down from 10. My CaNO3 mixture is a bit strong so I've stopped dosing until I get near 0 NO3 again.
Pictures next post.
