Is it too clean?

Is it possible to have too many "clean up crew" members? I grow very little algae. I have 2 tangs, a blennie, a goby, foxface, clown, angel, black urchin, starfish, assorted snails, a hermit and 110 gal tank. They pretty much keep all the glass clean, and nothing grows on the rock except the pink and red stuff. I fed sparingly, couple times a day, but they go after the algae flake like they're starving. No algae blooms, no cloudy water, no off-the-chart chemistry (things are too perfect, I think!). Curious if I'm in "sterility" mode?:-/

 

well urchins eat a ton of algae! my clean up crew are a black urchin and stomatella and a few hermits!
I've never had an algae problem yet.

if i was you tho - dont get any more algae eaters - you may starve the urchin. They grow really big by the way

 

Long Spined are neat no doubt about it .
But those spines they carry are venomous, and they like all urchins are teriffic algae eaters , OH that also includes "coraline lines algae's".

Tuxedo urchins are KNOWN to have a taste for "coralines" and preffer it over every thing else.

Not to mention some have a taste for soft corals, and a pencil urchin can knock over just about any thing in its path.

You know guys, urchins are agreat algae eaters ,
( i wonder if one or a certain species would consume "bryposis" ? )

 

My LFS had a briopsis outbreak in their quarantine system. They have 1 urchin that they won't sell. It goes wherever there's bryopsis and mows it down. Scott said that they have to be careful with it though because when it runs out of green stuff it goes for the pink stuff and when it runs out of that...the corals. It's a tuxedo urchin.
