Poor PE, recovery time?

[Hellion179]

I purchased a frag pack that included several acros in it. I've been keeping monti digi and stylophora corals alive and very healthy for awhile now. Salinity is 1.026, Ca 440, dkh 7, ph 8.2, Nitrates are 0-5. I do not have a phosphate test at this time. The tank is fairly new, the rock came from an established tank. I am running phosguard in a bag in the sump, probably 2lbs of it plus about 2 lbs of carbon. I have an ES2 skimmer and am running cheato in about a 5g refugium.

On one of the corals there is some polyp extension, but it's tiny. On the others I don't see anything. The colors aren't super bright either, kind of pale green for the two and the blue ones look a little better. I acclimated over 2 hours. I have 2 Koralia 7s and 2 koralia 1s on alternating hydor 4 wavemaker.

Just wondering what I should do or if I should do anything.

I didn't place them in the sandbed. They came from a MH tank, so I cut the photoperiod by 4 hours and have been upping it by 30 minutes every week.

What happen after one hour light turn off? Do you see PE then?

 

[Hellion179]

To be honest I haven't really looked after lights out. I will today and report back.

my polyp extension is best when i can find good random flow for my SPS. Most of my acros love lots of flow with random being best!

Best of luck!

2lbs of carbon and gfo? That seems to be a ton. I would go to the brs reef calculator and calculate . maybe you have a gigantic tank or a typo?

 

[Hellion179]

Typo. It's a little less than 1 lb of each after looking at the containers.

I used more than what is probably suggested because its in a bag and not being run in a reactor.

Is there harm that can occur from running too much? If so it's unrelated to the corals, because I just added that stuff recently.

 

[fishguy597]

Still seems to be a bit much IMO. How big is the tank? Are you having algea issues? carbon and gfo strip a lot from the water column. seeing how your tank is new I would cut back if it were me.

 

[Hellion179]

What would you cut it back to? It being in a bag I figured it wasn't going to be very efficient.

The rock had a lot of hair algae on it when I got it, I scrubbed it down before I put it in the tank but I figure it has to have absorbed some good stuff in the old tank.

I moved the corals down to the sandbed. Going to take pictures and post them in a little bit.

 

[Hellion179]

These are the three I'm concerned with. They look pretty much identical to how they looked a week ago when I got them.

 

[Hellion179]

Oh and this is under 10k 250w MH. Under actinics they're blue, green, and blue/white.

How big is your system? my system is 285g and I only run .25 cup of gfo! and around the same with carbon! I run my carbon passive in the sump and gfo in a reactor! running the amount of gfo could be part of your problem! good luck! 1 table spoon of gfo per gallon of water! I cut mine in half and run on the lighter side and have no algae issues! Chef

I would check them after the lights are off and see. Usually at night time is when most pe occurs

 

[Hellion179]

I checked last night and there was for sure more PE, but it's still pretty minor. I guess I'm just going to have to wait and see. Anything I can do to encourage it? Flow is super random and I hope dropping them down to the sand for a little while will help them out.


It's 180g total. 18 tbs is one cup right? I used what is the equivalent of probably a heaping cup, hehe maybe a heaping cup and a half. I am having some minor algae issues. Rock that broke off onto the sand bed is growing hair algae like crazy. But the actual rock work looks good. The sand bed has some algae growing on it that's not diatoms.

The first photo and the third photo look like they can be saved. But I would frag the one in the middle. I have a feeling that the tissue recession you can see in the photo will continue if not fragged.

Just a thought.
