Water flow question. Please help

[JustVibe]

I have a 35 gallon nano tank with 1 wavemaker (Tunze nanostream 6040) that keeps the few coral that I have happy.

However there is some rockwork (1 solid piece) sort of cave that doesn’t get airflow. Bubble algae starting to form/sand settles there. Due to the positioning of the first wavemaker and my already happy corals, am unsure where to add the 2nd wavemaker or if really needed.

Trying to avoid cutting the rockwork cave piece since it is glued together to the archway rock and hand sawing was the bane of my existence. Any suggestions? Is using a turkey baster to blow debris from cave enough?

push water with two wave makers...one on each side of the tank....
I found adding one to the back of a tank and push water to the front glass works great ..

That’s what I hear. In my situation are you suggesting putting one on the right side of tank that pushes water to the left? Then I guess turkey basting the cave area?

I have 6 powerheads in a 36x22x22" SPS tank, two Tunze orca 6075s at 80%, two MP40s at 75%, a Nero 5 at 50% and a jebao MP40 knock off I can't remember the settings. I still have to blow the rocks off with a turkey baster every few days or I'll get bubble algae in rock openings where detritus collects. I've never been able to get flow to keep detritus from settling somewhere. I blow rocks off in 4 tanks at least once a week using a baster.

I agree I would add another powerhead, I like positioning powerheads against each other to so they bounce and create random flow patterns.

In my curremt RS170, 35g nem system I run 2 powerheads.
A Jebao dmp20 and a Jebao OW25.
