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!

I had to choose the first one, although the reality is that it happens 24/7/365. I have a couple powerheads on either sideof the tank near the bottom whose only purpose is to maintain excellent flow in and behind the rocks.

This is one of the reasons I asked, I've had tanks with crazy flow and blowing out the rock work still cleans out crevices inevitably. It's simply unrealistic (in my experience) to have enough flow to clear out every single crevice, I'd say grab a turkey baster and give it a shot. It may surprise you!

Even bare bottom tanks with numerous panta rhei pumps I've been able to get detritus out regularly!

I am currently doing it daily. I slacked off for a while and my rocks are super dirty. Before I was doing it weekly. I have a cube tank and I have a couple low flow areas that build up quick if I'm not on it.

I voted monthly. But I usually do it more often. I do weekly water changes. I blow off the Rockwood or stir up the sand while using a small hose to pump in the new water. It only takes a little extra time and I think it worth while. I add in some clean socks to catch the junk. Or a polishing filter to my redsea. I have multiple tanks.
