montipora and 7.8 ph
 

everyone I just had to question about the and some corals I have. My parameters are as follows
ph-7.8,
salinity-1.024,
ammonia-0 PPM,
nitrites-0 ppm,
nitrates-2-4 ppm,
calcium-520 ppm,
alkalinity- 8
phosphate-0 ppm

I've had the tank running for about 3 months now and montipora, green star polyp. Ive had all of them for about 1 1/2 months now except the about 1 1/2 months now except the GSP. I've had the gsp for 3 weeks now. When I put in the montipora it was a very nice light Orange but after a week or so it turned brown and seems like its not growing. It still slimes up so I'm thinking its still living. My question is what could I be doing wrong? The montipora in the. Lfs is orange while mine is brown. I used to see the little tiny polyps on it come out but not anymore since it has turned brown, I don't even see white edges indicating new growth. Could this because my ph isn't 8.2-8.4? Help me out guys Ive been racking my brain as to what it could be but cant figure it out.

What kind of lights do you have???


What kind of lights were they under????

What time did you test your pH? pH is best watched with a constant use monitor, it changes throughout the day and is amongst other things a CO2 indicator, I can see more than a .2 swing minutes after firing up a couple burners, and the oven on my range. About the plating monti, sps are finicky corals many things influence their happiness; I'm a bit concerned that it is slimming up, it should only do that if its being stressed.

I have a t5 4 light vho fixture about the same as lfs 2 actinic blues and 2 12,000 k, lfs had 2 10,000 k. I tested yesterday around 2pm and it was 8.0 but only because of no water change 4 about 3 weeks. I was doing them every two weeks but ph would always stay below 7.8 now it swings from 7.8 to 8.0. The montipora only slime up when I touch them or move them which isn't much. I havent glued them any where yet until i can figure out whats going on. I have 3 koralia circulation pimps going, could that be too much current?

That could be the problem right there, sps really need stability and moving it around doesn't lend to that. As per flow, unless its getting straight on blasted from close distance I wouldn't suspect that's the problem. How is your coralline growth, a rule of thumb is you should be putting a good bit on your un-scraped glass for good sps growth and colour. Last thing coming to mind, I use polyp extension as a very good indicator that the coral is at least holding its own.
