Wavebox maintenance

[marie]

Dave (Mrfish55) was over the other day and asked if I had the box turned way down. I didn't but I knew it was way over due for cleaning so today I took it apart and cleaned it. I have sponges growing on my sponge, feather duster worms 6" long, coralline algae (How does it grow in there it can't possibly get any light ) bubble algae, snails, worms and pods galore.
After putting it all back together and turning it back on I realized it was operating at less than half capacity before cleaning. Should these things be cleaned every 6 months? (well mine should be obviously) .

So have you cleaned your wavebox recently?
