No polyp extension

[Micki]

What causes there to be little to no polyp extension? 99% of my SPS don't show polyp extension. I do some phosphate issue. But is fairly well controlled with a phosban reactor. Any other reasons?

Any PE at night time?

what kind of fish do you have in yoru tank?

 

[Micki]

Powder Blue Tang
Yellow tang
hippo tang
7 chromis
2 false percs
1 lawn mower blenny
1 mandarin
1 yellow clown goby
1 coral beauty
1 flame angel

I bet yoru clown goby and Flame angel have somethign to do with it

 

[Micki]

To every piece? I got several new frags in. They had good polyp extension for a while then slwoly went away. I do the yellow clown perching on some of the pieces but not all of them. I have never seen the flame touch any of the SPS.

 

[Julio]

Well, how high are yoru nitrates?

 

[Micki]

I haven't tested them in a while. But when I did they were not 0 but very low. I forget the exact number.

What do you use to check salinity? I had little polyp extension until I spent the money on a Refractometer. Found out my salinity was to high using a hydrometer. Just an idea.

I only use a refractometer. Thanks though.

I removed my yellow clown goby from my old stonies tank because it caused polyp retraction. Within a week of removing it, polyps were extended again.

In my new stonies tank, I have an african flameback pygmy angel, it nips enough to cause polyp retraction. I will move him to my softies tank once I catch him.

In short, fish can cause polyp retraction (I am sure it can be caused by other things, but in my case was due to fish).

Hmmm, I just don't see the goby or flame angel causing this. I could be wrong though. I'll keep an even closer eye on them.

Thanks!

Any red bugs.

Not that I've seen. Wouldn't they be fairly obvious?

They are very very hard to see without having a trained eye. I would take out some of your acros and do the turkey baster test on them.

Turkey baster test?

I've had the same issue for awhile...mine are slowly coming back. I thought it may of been from dosing too much Kalk....maybe throwing off the PH. I have since bought a PH meter and PH seems ok....do you dose Kalk/calcium?

Take one piece of sps out of tank for a second and BLAST it with tank water with the baster over a white or clear container. If you have bugs, you will start to see them move around in the container.

 

[Micki]

Hmmm, I'll try the test.
