bubble coral

pH is 8.3 at night and about 8 in the morning. Right im just not sure. I have been doing about a 15G water change every week for past two weeks to see if that helps, it does seem to be going away alittle. Grateful for your input

 

Which i could help you some more but im a little baffled

Maybe someone else here have some answers for you

Sorry

Marc.

 

How close is the bubble to the other corals? Are you running carbon?

 

bubble is at least 6-8 inches from anything else. Yes im running carbon amcarrig.

 

Is there a ground probe in the tank? How are all the other corals doing?

 

i have read lots of post about ground probes and may add one shortly. I dont have one right now. Everything else is doing great

 

UPDATE: I tried moving the bubble and nothing. about 2 days ago, i was looking closey at it and it appeared to have some rather large pieces of sand stuck by its mouth. i waved it around in the water for a while to dislodge them, its now opening up alot more, not as much as before but i think that its doing ok now. thanks everyone

 

great i hope its all better.those with things could be either urn sponges,they look like lil white pods about a quarter inch long with a feather duster like fan coming out the top.or they could be sea squirts aka tunicates.usually they grow in colonies and have 2 tubes per pod,one inlet,one outlet.they do filter your water so keep them.
