Dieing SPS

[RobNJ]

Not sure what to do, I have one piece of SPS and after several months it is turning white.

The picture with the flash make the ss look brown but it has thie amazing green glow under the halides.

Can anyone tell me what may have happened? and what I should do?

All parameters are good and in range. Tanks is up 6.5 half months

What kind of flow do you have?

 

[RobNJ]

Seio 2600 For tank flow
Return is Rio 2100

Lots of flow, I do not think thats the problem.

 

[Justin/TiV]

how big is your tank...thats not very much flow IMO

 

[RobNJ]

40g tank, the SEIO IS 2600gph and the RIO IS 600

Thats 3200 gph total.

What are your parameters? Just out of curiosity.

 

[RobNJ]

calc 460ppm
dkh 7.5
trates/trites/ammonia 0
ph 8

I would try and frag a couple pieces from the side that is not RTNing and hope for the best. Good luck and keep us posted if you find the culprit.

Do you think 20k MH is a bad choice for clams and sps? I know that there are differences in PAR with 10k vs 20k, do youthink 10k would give sps and clams more growing power?

How stable are your parameters? Do you have any large temperature swings or large swings in your pH, alk or calcium?

Also, what is your phosphate?

This is off... Check the RC alk/Ca calculator... these two need to be in balance. As for your RTN, I'd bet you a shiny new dime your alk dropped below NSW levels for a period Put some buffer or baking soda in the tank, get that alk up.

I was thinking about starting to drip Kalkwasser, maybe i should have thought about it sooner.
