can this be stopped?

[chappy121]

Little help please.

I just upgraded my tank from a 72 to a 180 and some of my corals are starting to die at the base. see pic. The water quality is fine. The only thing i can think of is flow. My tank is now running a dart for the return and a dart for the OM 8way, but it took me almost 2 months to get the OM hooked up. It has now been running for a week but the regression doesnt seem to be stopping. So could low flow for a bit cause this? Will it stop? What can I do?

Any help appreciated

Fragging might be an answer, but it's a pretty specimen and a shame to break it up. It's a fairly small area. If you can get the cause, it might regrow, but you have to turn that situation around.

Check your ammonia, too: that is one prime cause of that problem.

How fast is the regression? I my experience, the extra flow should stop the regression.

I find that STN is a good indication of salinity being off. Just a note to all: when asking for help please post all your tank water parameters, lighting and other info that may be helpful. This way people can have a better idea of whats happening and be some what helpful. With out the water parameters it is nothing more than a crap shoot. If you want some serious help list all parameters.

i havent tested in a month which is why i didnt post them. will retest tomorrow, but this is what the water parameters were when i first noticed the regression.

Temp SG pH Ca Alk NO3 PO4 Mg
79 1.024 8.2 360 10.6 0.02 0.03 1140

sorry, its a bit late and i am a bit tired, but the water parameters were taken on june 11. i do a 15 gallon water change everyother week. last change was last friday.

To me every thing looks ok except get magnesium up to 1300-1400 and lower phospates to zero. It may be a flow issue as you stated. I would frag the coral or at least frag a section which hopefully will survive in case the mother colony does not. Are you sure there is no bugs of fworms or something causeing this. Just a thought. I wish you the best.

do you see any flatworms? or red bugs?

[chappy121]

you know i dont think i have any flat worms or redbugs, but will take it out and check tonight. guess i will also be fragging a few of my corals also. very sad....

i have the same coral as yours and it bleach the same way.

Also raise calcium to around 400 but get the mag up to help balance the alk and calcium. Please use a refractometer to check salinity it should be between 1.024-1.025 thats all I can think of besides of everything else that was posted. Good luck

 

[chappy121]

thanks michaeal for the posts. i actually do use a refractometer but i probably should make sure it is accurate just to be sure. and i have been dosing with turbo ca and kent mg to get the CA and mg up.

thanks again for the advice!!!

 

[chappy121]

I retested and pretty much everything is the same except the Mg is up to 1260. I am dosing with turbo ca and salt to get those back and will do a water change this weekend. However i am still seeing recession daily. The question is should i also frag immediately? Please advise.

thanks!

The green skeleton in the fist picture make me think that this is a Po4 problem.

yeah, i have a phosban reactor that i am thinking of starting up again.
