Sps losing tissue

Volpone · Apr 11, 2015

Hi reefers:
I was preparing my tank for long time to start stocking it by sps , my first try was last year qnd i did very well keeping frags abd grow it .
I get busy for 3 months away of tank and i move all my sps frags to A friend tank.
Before 2 months ago i start stocking sps again but colony one i lost 2 pcs because alkalinity swings trying to stabke my parameter usings B-ionic 3 parts dosing liquid .
I start notice that my colony gettings white tips as losing tissue .all my parameters is perfect now but what cause that buring /white tips of my sps .
Water parameters :
Ca: 430
Mg:1320
Kh :8.00
Nitrate : 0.5
Po4 : 0.05
Im running radion generation 2 pro with 70 % intensity

Alk burn?

sharkboy99999 · Apr 13, 2015

If there's no algae growing on it then its probably growth, test every thang . I wouldn't frag it till algae grows on it

Algae generally starts growing on dead coral before anything else. Unless you are running a ULNS, which according to your numbers, you aren't, pretty soon after tissue recedes from the tips, they will become covered in algae. I agree with the others. It looks like new growth.

Are you using gfo? Carbon source? Dosing any potassium supplements?

Defiantly looks like some of the new growth has been burned. What is your nutrient levels and what were they previously when the coral was added?
