I bought a power head so I can start. Was thinking of doing it maybe twice a month. But I might follow your lead. Thanks!I wanted to start a poll to see how regularly people blow out their rock work.
How often do you blow your rock work out and how do you do it?
It's something I've started doing a few times a week, and since doing so I feel like my general tank health has really improved. Random clumps of algae have been disappearing and corals seem happier with better polyp extension too.
My hypothesis is this helps get all the gunk out of the rock work that acts as (essentially) fertilizer to algae, as well as encourages liverock to absorb excess phosphates. I also believe phosphates wicking from the rock work, into the bases of large SPS colonies where their base gets minimal flow due to growth could lead to RTN and STN events.
Those are just my hypotheses, and I would be curious to hear anyone else's thoughts/experiences!
^^^This^^^The answer is either Never, or Four times a day, depending on your definition of blowing out...
I have a pair of Tunze 6105's connected to my Apex. Normally, they run a 1 minute ramp up, 25 - 40%, inverse, meaning one is ramping down while the other is ramping up, then they swap.
At 6am, Noon, 6PM, and Midnight, I kick both 6105's up to 100% power for 2 minutes. Really moves some water... Each is rated at 3400 GPH, with both running full out, there isn't anything settling in my tank. In fact, I've had to glue down my frag rack Fish seem to have gotten used to it, though they freaked out a bit at first. Don't seem to mind anymore.
Nothing there to manually blow out
