Ok guys, need some help!
Had a couple things going on with the tank lately and it's having an affect on my sps.
First, my ph was going down below 7.6 in the mornings. Got that taken care of by making adjustments to my calcium reactor by changing the feed pump and co2 settings. But while this was happening, my Alk was bouncing around. Not a whole lot but it went down as low as 6.5 and up as high as high 8's. I normally keep it around 8.0.
Second, as I was getting the reactor pretty much dialed in, I added the Radion diffusers.
My lux meter didn't record much drop in light, just a few % but Ecotech says they record PAR drops of around 20%. So considering that, I should have been upping my overall brightness, but I only upped it about 5% and then forgot about it.
So thats the two things that have changed/been happening lately.
My Alk is now a steady 7.3 for a week.
BUT... this past week (or two) I've been having problems.
My SPS are losing color intensity or browning out. My Milli's have turned brown, my Paletta Pink Tip lost it's pink... almost white, but still have the green. Some other greens dulled out. Blues dulled out. Purple Bonsai has dulled. My ORA Joe the Coral has STN's to almost nothing. I lost two frags, RTN's overnight. All sps and zoas seem just dandy.
So first I was thinking alk instability... but it wasn't THAT bad. It's not like it shot up to 11. And the changes weren't overnight, they were over a few days.
Then I remembered about the light. Could the decrease in light have caused any of this?
Parameters are all stable and in line.
pH now ranges from 7.76 to 8.0.
Alk 7.6
Calc - haven't checked in awhile but was around 430
Mag - 1400 last i checked
Salinity - 1.0256
Nitrate - 2-3ppm
P04 - haven't checked in a while, but was .04
I'll try to update some of the above parameters later today.
But any thoughts on what's going on?
