Thank's for the welcome greeting. I change all my rocks from my old tank to these Fluval Evo 13.5(three months old now), my old tank was 5 years old, I change the stock light and my acros are under 350 par, the first picture acro was slowing dying and wen I put it on the sand, it came back so I realized these acro was in deep waters. The second and third picture belongs to a new acroporas I put them in my tank 4 days ago and I glued them with super glue and I think it stresses them a lot, and why I sed these, because few minutes later I put them in the tank, their polyps was really open and after put them back in the tank they closed their polyps again. I don't now what kaind of acros I have and I don't now if they really needs to much light, the acros are 8 inches from the light source and the lam is 4 inches from the surface water.
temperature: 77
ph: 8.0
nitrite: 0
nitrate: 0
phosphate: 0
calcium: 400
salinity: 1.023( maybe it is the problem)
Flirtation: two little bags of chemipure blue nano
