I feel like I need more flow... but...

[krs1102]

Hi everyone,
I have a 125 gallon tank with a some LPS corals (hammer, elegance, trachy, Duncan, Blastos...). I have enough flow in the tank to be right around the 10x flow range (although I'm probably a little under that).

I am having some issues with algae/debris settling in the sand/rocks. But the corals seem happy. They're fully extended and have been for months/years, so I don't really want to change things up too much to possibly mess that up.

Any thoughts?

Thanks in advance.

Small powerhead placed to move water in that area.

IME/IMHO, if there is detritus settling somewhere you don't have enough flow.

I have a pair of koralia 850gph power heads on either side near the bottom positioned to keep water moving behind the rocks.

I got that in my rock only tank I keep about 100-150 lbs of live rock in and its a much smaller 55 gallon tank!

You dont absolutely have to get bigger powerheads but you might need another smaller one or two positioned just right to get things in suspension so your filtration system can do its job and get it outta there without blasting your corals. How much flow you got aint nearly as important as having the right kinda flow in the right places. Your other options is use a Koralia Nano and periodically blow things down and get it suspended in the water column so that filtration system can deal with it.
