SPS keepers...no alternating current?

[SuperFudge]

Hey Mason,
I dont use one nor care to,i dont believe they are worth their money for what benefits they might achieve,provided a generaly high volume and chaotic current are still provided.

Good for making sure detritus has less places to sit though,as with constant outputs there are low current areas that will always tend to accumulate it.
Nothing that a good powerhead blast wont fix.... ;) .
Even with wave makers we will still have detritus accumulating in areas,that will eventually need a blast with a baster or powerhead.
