Couple of ?

[drillsar]

I just got another powerhead total of 2, Where should I position them?

I think my bubble coral is dead only a couple of polyps left, im hoping I can save it, I will show you pics, I think I have to move my Zoo's there on top right now and I just switched to a t5 light.


Im also thinking of replacing my sand bed but im not sure if I should go shallow bed 2" or DSB 4.5"

Dont want to start off negitive but this is why research and patiants are the key.

If you upgraded your light then decrease main light time for awhile and let coral reajust to higher lighting.
Do you feed them?
DO you know your water readings?
The increase in flow could have kick up nitrate or bothered the coral.

I didnt think I had to feed these types of coral. Well the bubble hasnt doing well for awhile.

What kind of powerheads? In a 55 you could still use more than that. I have 5 in my 55. Why do you think your bubble is dead? How long has the tank been set up? You know corals need acclimation after switching lighting right?
