With a little more time on my hands like many of us, I’m trying to get a handle on several issues in my tank.

I have a 90 gallon tank and sump with about 25 gallons in it, salinity steady at 1.025/1.026 using a (Tunze ATO), temperature between 76 and 77 degrees regulated by an Apex EL system I bought back in January. That’s helped me get things back on track, or at least it’s got me thinking about it.

I have a light bio-load, 2 Clownfish, and one Orchid Dottyback. I lost one Kole Tang and Neon Gobie a year or so back, the Clowns and Dottyback I’ve had for about 4 years. I have a few LPS, doing better now that I’ve lowered the lighting and testing on a regular schedule every few days. I'm running a sock and have taken my Lifereef skimmer out of the sump for now. I do need to rent a PAR Meter. I have a DYI (ReefLEDlights.com) fixture, I know I had the LED's set too high and have since cut back on the lighting intensity. My duncan's have been doing much better.

My other water parameters.
Calcium is 440 ppm (Red Sea Test), phosphate .020 (Hanna Checker), alkalinity is 9.7 dkh (Hanna Checker), and magnesium is 1600/1700 ppm (Red Sea Test). Nitrates (2,5) using the ELOS test kit chart. PH is running 8.01 to 8.06 Apex Probe.

I’ve been dosing (KNO3) potassium nitrate the last week or so to raise nitrates until I dosed, I had zero nitrates in the tank.

I’m trying to get Coraline algae to grow and take over the rock and knock the algae off with no luck so far. I have hundreds of tube feathers of some type I’m hoping will go away too.

I plan on getting a few more fish when I get things turned around a bit. A yellow or kole tang and a small group of bangi cardinals.

Any suggestions or comments would be appreciated. ;Cyclops

Sure:

paint the entire inside of your tanks with black plastic :)

Seriously: the dripping kalk, while anecdotal, does "appear" to help...esp when maintaining a alkalinity above 8 and a pH above 8...
..and yes, coraline does seem attracted to black, or at least it seems to start on black things first...no doubt a scientific experiment will prove that wrong...LOL
edited to add: You'll know things are cooking just right when you gotta break out the razor to get those lil purple specks on the front glass
 
I'm in the process of switching salt, probably a bad time to do it. Moving to TropicMarin salt, I decided to do that a few months ago. I have one more water change then its the TropicMarin salt. I'm not dripping Alkalinity or Calcium yet, I do have BRS dosers ready if I need them. I have some extra time to experiment.
