High light. High flow.

My tank is doing well except ..... I can not keep an encrusting coral at the top of my rock work. I have about 5 branches of tonga sticking up in the center of the tank. The PAR there is around 450. I have bought 3 different encrusting frags and none made it. I acclimated every one and they did well lower in the tank. It was only after I raised them up did they go south. Only one died but the others are hanging on by a thread so I lowered them last night to see if they will recover. I have other SPS that is doing great. Actually everything else is doing really well.

So my question is ... Is there any encrusting SPS that can handle this position in the tank? Looking for suggestions.

I have a chip's acropora that's growing like a weed in 350-425 PSR right now. The other montis and acros are in the 275-325 PAR range.

I have a stylo and chalice at the top of rock work about 1”-3” below water level

I have some corals that high. I just don't want to add anything that will shadow because of corals below. So really looking for something encrusting.
