Corals feeling bad
No idea what happend.
13.5G Nano reef
Reef Crystals salt mix
1.25 salinity
Arround 7-7.3 alk
0 nitrates
0 phosphates
3 tbs of Carbon every 2 weeks
Purigen (I need to regen it, it's brown)
Filter floss
Two Candy Cane died
Xenia died
Kenya Tree Coral feels very bad and will die soon (at the beginnings it feels very well and spread)
Ganiopora feels bad
One Zoa died
Green Mushrooms feels fine
Two Zoas also very fine
Mushroom Leather is fine
All crabs, fishs, snails, shrimp and one Urchins fells fine, no dead at all.
I dose 1ml of vodka, nitrates and phosphates = 0.
I feed the corals by Reef Roids twice a week and dose Coral Accel 1ml daily.
The only changes in my tank is full elimination of Grape Algae by manual and hungry Urchins. And digging from Pistol, all dirt (white dirt) from sand going to rocks and filter.
Stock:
2 Small clowns
1 Yellow Goby with Tiger Pistol Shrimp
1 Emerals crab
3 Blue legs hermits
1 Turbo
3 Trochus
2 Nerites
1 Nassarius Snail
1 Cerith Snail
Coralline exist in the tank.
Stock light. One 240 GPH pump and 265 GPH Eheim pumb. Lot of flow. Fluval SEA PS2 Mini Protein Skimmer.
Temp is 29. Even with heater off. Maybe from light and eheim pump. No way to reduce it right now.
Any idea what happens? What it can be?
Thanks
