Polyp Bailout!

[Shtiff1]

I have had several corals ; Duncan, Frogspawn, Acans, and Dendros. They all have had polyp bailouts. Trying to find out if there is a definite cause for this. All corals are in there suggested places. Tank is a 125 with 2 sets of T5 HO's, 36".parameters are as follows...

Salt- 1.025
Ph- 8.3
Alk- 8.5
Ammonia - 0
Nitrite - 0
Nitrate - 7
Cal - 435
Mag- 1320
Temp- avg 80
Phosphate - 0

Running carbon and dosing vodka ; 4.5 ml / day
Water changes are done every week ; 10% using RSCP salt.

Any help would be greatly appreciated.

Thank you!

2 sets of T5? How many lamps? How long have you had the corals? Whats the flow? Thats the only thing I got for ya, your parameters are all in check.

Yes 2 sets, 8 bulbs, about 1 year, good flow Snapper /dart reeflow pump

How old are the lamps?

Take a couple cups of the sand bed out and smell it. Sometimes there can be too much decay under the sand bed that goes unnoticed. If so replace.

Would a good vacuuming do it?

Man, I have no idea. Everything sounds good.

That's why i posted, because I don't have anymore guesses :-(

do you have any cyano or algea in the display and do you have a refugium

 

[Shtiff1]

Maybe 2 spots of cyno about the size of a nickel. No algae

Where did you acquire this method/info? 5yrs reefing and I've never heard of such a thing!

Are you dosing anything at all? I see you mentioned vodka. Anything other than that?

this is a good line of thought also maybe too much flow!?

Magnesium - 5ml/day
Alkalinity - 30ml/day
Calcium - 30ml/day

All the spoken of corals were in low flow

Anytime I'm having problems with my tank I go back to basics and start over.

If it was me I'd stop dosing vodka and everything and start over. Test like crazy until you find out how much your tank needs to be dosed. Do you have sps or clams? If your tank isn't hard coral heavy you may not need to be dosing much, especially using RSCP salt which is high in alk and cal anyway. Any reason you started dosing vodka to begin with?

Polyp bailout has been linked to enviromental stress.

Have you looked in the tank at night for a bad hitchhiker that might be harming the corals? Any hungry peppermint shrimp?
