Just an update of my own tank.
I siphon my tank weekly/bi-weekly usually.
Even though there isn't much detritus...maybe a teaspoon full if I find a sweet spot.
Today it is overcast and drizzling a bit so it is a good day to do some maintenance.
I siphoned, not much at all came out.
"What the heck...I need to powerhead the rocks anyway." I thought to myself.
So I get out the good ol' MJ 1200, plug it in and let it rip.
Holy cow wa there a lot of dust and silt coming out of certain areas.
My tank got pretty cloudy.
Alot went over the overflow to the filter sock, some landed on the starboard and I am sure some went right back on the rock.
In a few minutes I am going to powerhead them again...and maybe one more time.
I do have a problem with bubble algae in a few areas, and Iwill say that 99% of the rock that got powerheaded and released a lot of detritus does have a bubble algae problem.
I wonder if putting all this detritus into suspension is bad or good for SPS.
Hmmm...if I did this at night all my corals would be feasting.
Just some observations and a little reinfrocement on the keeping your rocks clean.
