I've picked up a few weeks ago a 24k psammacora which broke in half when I tried to remove it from plug to place in tank. Over the past few weeks it seems to be surviving, but receding. Just trying to understand if it is a flow/light issue or a parameter/stability issue.
Tank 4 months old, fish doing great, LPS doing great except one octospawn died. A few SPS frags died. Parameters have been mostly stable, but salinity jumps around a little due to constantly fiddling with the red sea overflow which doesn't want to stay stable.
Lighting is a Reefer 90 which I have on 23k. When the psammacora first went in, I did a dino treatment of 4 day lights out peroxide every night and bacteria every day then brought the lights back to 100% over 7 days from 50%. This is when the sps and octo died. Since then I have set the light to 80% max but brought it back up from 60% over 20 days. Never again will I do this as I assume this was the cause of death.
Parameters are as follow:
Salinity 35ppt (up to 37 over a week due to overflow adjustments)
Nitrates: 10ppm steady for a month, but just went up to 20ppm in the past 4 days due to addition of new fish and heavier feeding.
Phosphates: 0.04-0.12ppm with most of the month being stable at 0.12ppm
alk: 9.2-9.5 slowly creeping up over weeks after the sps died so i stopped dosing to keep it from rising further.
pH: 8.2 rock steady for over a month
Flow was high when I first added everything and the LPS looked like it was getting blown away so I turned everything down to medium strength.
Any tips on how to recover the edges of the frag or just leave it alone and let it recover over a few months?
