Well, one powerhead is back in the swords, near invisible. And the 2nd powerhead is behind the large driftwood, near invisible unless you are in the right side of the tank, then you can see it. Yes, the intakes of the powerheads get clogged now and then and need cleaning. And since adding the powerheads, my XP3's been getting clogged in less than a week due to the current getting more crud waterborn til the XP3 picks it up. It's hard cleaning a very dense forest, lol.
As for the powerheads, they are the MaxiJet 600's.
Oh, and no, the powerheads are set so my plants aren't going crazy in the current. You just have to know how to set them up in your tank.
