I started off using a par 30 led spotlight and it grew ok but I switched to a 50w grow led from Amazon and the stuff grows like crazy. All I have for flow is the water running through my sump so I don't thing that is your problem.
Also fluconazole treatments always kills my chaeto so if you have using it that may also be the problem.

I will discontinue the Foz Down and ordered a replacement bulb which is designed as a grow bulb. Do you think I can remove the maxijet from the live rock and chaeto compartment?

I used a compact fluorescent clamp light myself, it worked fine. It looks like you have measurable nitrates and phosphates, so it should be growing.
Maybe try changing the bulb in that clamp light to something more plant spectrum (6500 k) Seems a little overkill to buy an expensive LED system just for chaeto. That little light should work.

Good luck dude!

Thanks for the advice. I thought the flow through the baffles to the return (fuge is in the Center) would be suffice for growth. I definitely am trying the grow bulb before purchasing an expensive led fixture.

For me was most dealing with the flow, I find out in my case that more flow was better, but that just my experience...

what are you using for flow besides the overflow and return pump?
