Hello everyone i am currently having issues with my lighting. I am unable to get a par meter because it is nor available where I'm from unless its over $2000.

Well i have bleached everything i put on the highest part of my aquascape. Montis and a bali slimmer. Well i am tired of buying new corals and seeing them bleach out.

I am suspicious it is my light because i have nursed a euphillia and the slimer from near death. After the slimer got better i started ramping my lights up for 15 days and then it started bleaching (only parts that got exposed to light the most underside is ok) sadly no long after it perished. Few weeks after decide to get a monti cap and digitata, did well for 2 days then they started bleaching starting from the parts with most light.

Im really confused on what to do as my euphillia is happy (low in the tank), and my zoa is too. Water params are okay.

Info:
Ai hydra 32 and 26
Tank size 95x35x50cm (low side) 65cm (deeper side)
22 cm from light to water surface, 42 from light to highest point in tank.

Ive used this light for acros and they grew really well, no bleaching nothing in a biocube 32 thought it would be weaker here but i guess no. I haven’t taken the plunge in harder acros just yet in this tank.

Im using david saxby’s preset dialed down a bit.

I have to compare my setup to others since i can’t get a par meter.
