Help with SPS

Jason McK · #1 08-08-2003, 05:40 PM

I have 2 SPS frags both Montipora Digitata. They seem to be growing but they never extend their polyps. I have had one for about 7 weeks and the other for 6. My water parameters are all good
Ammonia 0.0
Nitrites 0.0
Nitrates <10
CA 420
PH 8.3
dKH 10.8
SG 1.024
Temp 79-82
They are under 2x250W 6500K MH with 2x110 03Actinics in a 75G tank. I have adjust my PH so that flow is strong but not crazy on both.

Any suggestions would be great

When strong currents blow them they seem to close up try lower flow and lower light. They aren't as light/current demanding as other SPS.

Maybe lower your nitrates.

Thanks Jack I'll give that a try.
