SPS polyp extension?

[Bill S]

Hmm. About the time you started having problems? What kind are they? I see from the first post they are 20Ks. That might be the problem, what did you have before that?

Also, I'd do a complete test on your system - what kind of hydrometer are you using and are you sure it's accurate. If you're nitrates are zero - what kit are you using for testing. I use Salifert, and it allows for very low level testing. If your nitrates are 0.00, then you aren't producing any waste... When someone tells me that their nitrates are zero, it tends to make me wonder. Another thought is that they might be starving? If your skimmer isn't producing, & you're feeding only rarely? BTW, mine are always over 10 - I try and keep them 15 or under.

that is kinda what i was thinking also bill, if you look at those pics, those rocks are spotless - looks too clean to me. maybe up your feeding slowly and see what happens.

I use Salifert kits. Also the skimmer doesnt produce anything at all for the last few weeks. I'll start feeding the corals more. The rocks are pretty clean due to this is a fairly new tank. It's just now starting to get corraline growing on the glass. The rock was mostly llive rock when it was set up with the rest being base rock. Most of which was swapped over from my other tanks. The bubls are as listed on the first post. Color seems to be coming back a little but that green coral is sluffing off and dieing on the bottom and inside areas.

I'm going to do another water test tonight and see what everything is.

three things come to mind when a coral is dying at the base:

1. high phosphates
2. low alkalinity
3. AEFW (lets hope this isnt the case)

It's only the one coral. Looks like low light areas but I dont know.

Ok. The tests are complete

Salinity 1.025 with Refractometer.
Water temp 78 on digital , 80 on mechanical.

These are Salifert tests.
Ca 370
Alk 6.0 DKH
Ammonia 0
Nitrite 0
Mg 1350
Iodine-Iodate 0 Clear

Red Sea tests
Phosphate 0
Nitrite 0-2.5 Was in between 2 colors.

that is pretty low on the alkalinity - i usually keep mine around 10 to 12 dKh. calcium could come up a bit too.

HAvent dosed ca in a few days so it is low. I keep it about 420. Will get the Alk up. Been using the home made brew but I might change to the B-Ionic again. Hopefully I'll have a Calc reactor tonight for it. New Top off and Aquacontroller real soon. I'm going to be like a pro reefer. Hopefully I can have the pro reefer tank too.

Hey, did you ever get any better polyps extension? I did a search for PE and found this post. Let me know what you found out. I'm having similar issues.
