carbon media

[lartho6]

i have a 75 gallon mixed reef tank with a HOB filter that i use carbon media, i am having problems keepping my zoa's open i have tried everything freshwater dip etc. my par levels are good could the carbon filter be the problem for them not opening?

 

[gilmour01]

what are your tank params and specs?

 

[lartho6]

my par levels are real good i have a duncan with about 30 heads two arco's a frogspawn with about 10 heads, a torch a few mushrooms and a lot of xenia's i have 2 vho's and 2 14 k mh's with 3 wave makers. they are all doing fine

I think he meant what is your
Phosphate
Nitrate
Calcium
Magnesium
Alkalinity
That sort of thing??

 

[lartho6]

ya i know they are all where they should be
ph 8.3-8.4
nitrate 0
calcium 400
magnesium 1560
dkh 12ish
salinity 1.028


with all the sps and lps i have shouldn't they notify me if something was wrong with the water.. i mean like the xenia's i know the minute the water changes they close up same with the mushrooms and frogspwan.. i cant figure out why half of the polpys open and the other half wont open i have dipped them in freshwater and still nothing. is there anything else. i can do. i don't run a chiller because my a/c keeps it cool enough i only let the temp get up to about 81- 82 and it drops down to 77-78 after the lights are off i have also sat and looked to see if i have a brittle star coming out and bothering them. i have one but i haven't seen him in about a month and its a small small small small brittle star.

salinity is on the high side. what wattage lighting do you have on what size tank?

water just might be too clean. prolific mounts of xenia can compete with just about anything for nutrients. zoas like dirty water.

 

[lartho6]

2 vho's and 2 14k mh's i had a few sps that i lost due to my a/c going out while i was gone for a week. that is why i have my salt at that level. but everything esle is doing good. ill try to lower my salt level and see if that works ill do a water change tomorrow and give it a few days and see

I would try an amino acid dip take 8fl oz of water to 10ml amino acids

 

[lartho6]

i will try.. thanks

how often are u doing the dips? if your doing them every couple days it could be stressing them even more than they may already be.

What kind of flow do you have around them?
