Hi

fairly new to reefing and although many things are doing well it seems these corals are dying. I tried more/less flow, higher/lower light to no avail.

I am now using reef roids i make in to a paste with no flow to feed.

90 gal 24x48x18
2x 40mph vortechs
4 puck AI Vega lighting ( 18% WH 60% of the 3 blues, 5% red& green.
30 total gal sump with refugium and skimmer.

Numbers seem good except nitrates around 20 and cant get to budge.

Let me know if you need more info.

Thanks

Sounds like nitrates, wc SLOWLY . Patience. My loose them. Need nitrates low to 0.2 for most
Corals. But every tank different. Take it slow. Hate to say it.
