Mike I put foam on the output and it worked great for the first 6 months. Recently it just became a waterfall and stoped skimming. I did a deap clean and after that it was micro bubble crazy!!

I added stuff to the baffles but there are not enough to be able to keep a stable water level as they fill with algea.

emac I've used multiple hob's in the past but since I traded for the ER I'll never go back.
