Having trouble getting acans and zoos to grow?

[ryan paggi]

All my sps corals are growing and my acans look great their big and puffed up but their is no new growth to speak of. My params are
Ca-450
Alk-11
Ph-8.2
Temp-77
No3-0
Po4-0
Mg-1450

I'm not sure what the problem is my tank has been setup for a year and I have had the corals for about 6 months. Any input would be great

do you feed them?

 

[Joeganja]

If their tentacles come out they are hungry they love to be fed

I feed ours 2-3x weekly I've got 8 babies started on a acan we have had for about 2 months and babies on multiple zoas in same time. I firmly believe they need fed to grow well.

Phosphates and nitrates might be too low at 0

 

[ryan paggi]

Yes I feed every 3 days. But maybe I should do more target feeding than just putting it in the tank

 

[steve&mari]

Make sure each head gets food and they do like low nitrates and low phosphates

 

[ryan paggi]

Yea I did that last night so hopefully they respond good to it

+1 on water being too clean if you target feed and all your sps are growing well. Its a pretty crappy balance to find in a mixed reef becuase obviously too dirty and your sps will suffer. I just feed my tank a little more heavy these days and it seemed to help and the fish are big fans as well ;)

i started feeding reef roids to my acans whenever i can remember.
i bought my frag with 4 heads. after feed its almost tripled in a few months.

Reef Chilli is a great food. Contains a ton of stuff that benefit coral. Spot feed acans 3 x week and give them Mysis. Med flow, mid to low tank. Halides or T5 for growth. LEDs if u want them to pop. I use a MH/LED combo.
