You're dong great with this!!
I am all skimmer!!
One of if not most important piece of equipment.
This is a picture of my MTC HSA 1000
It is about 4' tall with ozone being injected by an alita 6a air pump!
It is BIG $$$$!
I did not buy this unit!!!!But I love it!!!
Make a skimmer as tall as you possibly can to increases air contact time.
I dream of the 6-8 ' tall skimmer and most I see being clear ,I would watch it like the tank.
They impress me.
You got a nice build and knowledge base going on here!
Glad I found this thread!
