no pylop extention. what am i doing wrong!
well its been almost a month with out the coral beauty in the tank and im still not getting polyp extention during the day time. its starting to make me mad that i cant get my corals to open up during the day. at night there always open but close up right after the lights start comming on. im off to do a water change and test the perameters of the tank so i will post them later. any thoughts would be greatly welcomed.

Spazz, from what I have seen and heard. No polyp extension during the day is not really a bad thing and is not a good indicator of the overall health of the SPS. The polyps coming out at night is a good thing. Post your water testing results and we can see if anything looks like it needs to be tweaked. |

This is correct IMO, polyp extension is not a good indicator to a corals health. I have had corals with great extension while they are in RTN.

Check closely for red bugs too. Maybe do the turkey baster trick in a 5 gallon bucket with a few corals. I know red bugs can inhibit polyp extension quite a bit but your getting good extension at night. So i dunno. Maybe the bugs go more dormant at night if you have them?

I agree, it is not a major cause for concern. I know you did your 3 doses of interceptor so Red bugs shouldn't be an issue but keep a close eye anyways.
If I recall you have also changed the lighting not too long ago which could also take time to fully adjust. Even then some do and some don't with the MH on.

I just changed bulbs and had the same issue. I even had a little receding of tissue on a couple corals, which is not good, but has stopped. IMO It never hurts to run through all the little details, Ph and other levels including salinity, also maybe do a water change. It never hurts to do those. Good luck!

I think david could be right about the lighting.... Scott went from 250w MH to 400w MH with the cool guy reflectors... so there could be some truth in that.

That change in that amount of light could definitely be a cause.

well i checked the parameters of the tank.
no3-0
no2-0
ph-8.2 day and night.
ca-350 low
dkh 4.64 low
phosphates-0
well i cranked up the ca reactor higher and the co2 rate higher to get my levels up where they should be. my kalk reactor is doing a great job of keeping the ph right at 8.2 24 hrs a day. i have never seen it below 8.1 or over 8.2 so there shouldnt be a problem with ph spikes or drops. i know polyp extention is not a health thing i just think the corals look better when there polyps are out and flowing in the current.
there is no sign of the lrb's any more. the corals are coloring up nice and looking great. there has been noticable growth in the last few weeks. i think the lighting might have some effect on it but it can be the entire problem. i had the 400's over the 180 before i transfered everything over to the 120. the only difference now is the luminarc reflectors.

Your alk being low could have a slim effect on it, the ca being low should not affect the polyps extension. Do you have a magnesium test? Not that it would have anything to do with polyp extension but may be a problem of your low alk. The reflectors are not going to make a difference. Going to 400w from 250w could effect it but just reflectors aren't going to IMO.

scott-how did you measure your alk? that sure sounds like a millequivalents (meq) value and not dkh...in which case your alk isn't low-some would even say its high.

im glad you cought that. my kh is low at 4.64 where sea water is 8 kh. i wrote it wrong on there. i used a salifert test kit.
i have ajusted my ca reactor and done my water change then added some reef complete to try and bring up my ca and alk levels. i will be keeping a closer eye on these levels and bring them up slowly. don want to shock the system too much.
