NEED HELP STAT!

So I've noticed since I restarted this tank which has been almost exactly a year, slow growth. And I am having trouble with LPS all of a sudden. Most of them are receding. I'm wondering if I am running too much light on my system?

50 3w Leds half royal blue half cool white
Blue is at 80% intensity
White 100% intensity
Run for 8 hrs a bit more if you count the ramp up and down.
3 inches off the surface with no optics


Here are also my parameters, ...

A good friend recently bought a house that has a pretty sweet Reef setup, including a refugium.

The big issue is the owner completely neglected the tank for almost 2 years.

No skimmer, lights, water changes (just top off).

Total water volume is around 130 gallons, basement sump, Octopus NWB 150, BRS reactor with carbon, TLF Phosban 550 with BRS biopellets. I dose 3 vials each of Prodbio Biodigest and Bioptim every 2 weeks. I have around 100 lbs of marco rock. As for sand I have Tropic Eden Reefflakes. ...

So I have added a about 7 small mini Acropora colonies (more like large frags about 1.5 inches x 1.5 inches into my aquarium since the water parameters seemed stable enough and over the past three weeks my water parameters have started to take a dive. I've also noticed that a few of the Acropora colonies seem to be suffering from burned tips. No I have a very minimum bioload as there are no fish in my aquarium and I feed only twice a week. But I am curious what could be causing the drop in pH, ...

It has been long overdue since I've been on. A lot of new things going on. For starters I have another munchkin on the way. I recently acquired another dog to add to, what it seems like, "my zoo". I have decided that the tank that I started earlier this year will be called Little Ireland. Awkward name for a reef tank, I know, but it was started on St. Patty's day. Not too much going on with the tank other than some creature that appears to be wrapped around my birds nest anyone have any ...
