I can’t comment on the flow from pictures but you have aptasia likely stinging your torches, your phosphates are literally off the chart, your salinity and alk are a little low, and calcium too high.
I’d tackle the alk first and get it above 8 since that’s easy.
Phosphates are tricker. It’s likely going to take a long time and money to get them back down from that level. Start with adding some GFO, go slow so you don’t shock anything.
Your CBB will hopefully eat the aptasia long term, but immediately move the torches away from any that can sting the torch flesh.
The calcium is high but likely not an issue. The nitrates are also high but also not an issue imo.
Basically you have an extremely unfriendly tank for coral right now. Likely only some hardy softies will survive long term as you have it now.
