It's been over 4 months since my last update. Looks like I had all kinds of trouble with SPS at that time. I'm happy to report my SPS seem to be doing fine now. 40 pieces and counting!
Things I changed in the last 4 months:
(1) Parameters are stable now. Not quite stable enough but withing good ranges and very slow fluctuations if any.
(2) I'm running 4 wp25's, mp10 and a 1200gph return pump. I'm very happy with the flow.
(3) I have learned to place my coral very low in the tank for a while. Then when I see the coral color up I move it up about one inch per week or less. This seems to do the trick for light acclimation. I also have screen shades so I can drop the intensity of new lamps when I replace them.
When moving coral from LED lit tank I shade and place the new coral on the bottom.
When moving from T5 lit tank I place coral on the bottom and only shade for a couple of days.
When moving from MH lit tank I place on bottom and watch carefully.
Who knew you could have too much light? 250w HQI's are no joke!
