View Full Version : Acro bleaching!

Once acro starts bleaching from the base will it stop or continue until the colony dies? Thanks for any and all replies!

Bleaching from the base? or STN? Do you have any pics. Corals usually do not bleach from the base up.

It is turning white at the base and also about midway. It's a small frag that I've only had about three weeks. Don't have a pic....sorry!

ok, here are a couple of pics I just took. It's the small frag at the top. You can see the bleaching in the middle and at the base. Thanks!

it looks like stn or rtn not bleaching. you should try to frag it a little above the white part and get rid of the rest . it will ussally continue to die . sometimes you can save a frag of it most times the whole thing dies even if you frag it

Yep, That looks like it is peeling to me. If its just a small frag, you can try to frag it, nut I would just ditch it.

May be due to a large swing with my alk. It was at 6 meq/L and has dropped to about 3.5 meq/L now just within the last few days. My Ca. is still up around 520, you think I should start dosiing kalk again? I stopped because the alk. and Ca. had gotten so high from using a faulty test kit and what I thought was the right adjustments.

I have had similar problems,I read in sprungs book that it may be due iodine deficiency and lack of flow. So I increased flow to my sps and it seems like it slowed down the stn or rtn in one of my acros. I also had to frag my teal stag to a few pieces because it would have just died. So far I am just monitoring the tank closely,i am not too sure what the causes are but share some thoughts and answers if you get any.
