Having an issue with SPS I put in my tank. They seem to do well for awhile then they start losing tissue on the tips and getting what looks like brown algae but maybe it’s bacteria?
I’ll add some pics.
My parameters are fairly standard. And quite consistent.
My nitrates are between 10-15 depending how much I feed and phos 0.03-0.07.
Alk 8-8.5
Cal 425-450
Mag 1320-1350
Salinity 1.026
The tank is a water box reef 180, 5ft long.
I have 5 Xr15’s over top, I run it at 80% schedule. All blues and UV maxed and whites at about 16%. I’ve measured the par with an older apogee and I get highs of 230-250 where I put most my sps according to that meter. 12 hour photo period and an hour ramp on each side. So 10hrs at full light.
Am I giving too much light? Not enough light? By the par, if it’s correct I should be giving adequate light from information I’ve read. Definitely not enough to be burning the coral, no?
I have good flow in the tank with 4 MP 40’s on reef crest at varying intensities.
I run a 57watt UV.
One thing to note is I do have a serious algae issue, it’s a green hair turf kind of algae. Extremely hard to get off the rocks. Is it possible the algae is sucking all the nutrients away from the coral?
I use rodi water, and Red Sea blue bucket salt.
Tank is just over a year old.
Let me know what you think.
Thanks
