anyone use any night lights as I remember someone telling me there are
very
few dark nights on a reef. it's just my algae seems OK when the lights
are
on but first thing in the morning the brown scum is back on the rocks and
gravel. I have 8 red legged hermits but no turbo snails, should I buy a
few
for my 36 gallon tank. what about water movement, may more powerful
circulation pumps help out. this has all started from upgrading my MH.

36" x 18" x 15" with 36 x 15 x 12 sump with a Rio1700 return pump and
prizm
skimmer in the sump and 2 x 402 Hagens at either end pumping forward and 2
x
301 in the middle connected to a wavemaker. I'm doing 9 gallon water
changes every other day but its persistent.


Try pointing some of your pump current closer to the algae. I assumed it a
red slime type. Prune or manually suck those off but continue pointing those
current close to the algae. The reason for this is to move the algae by the
current and hopefully your skimmer will do the final removal. Make sure you
suck those algae at the same time as you manually pull those algae out. This
way, you will not spread to another place. Also it is to have current
everywhere to prevent any dead spot. Dead spot will promote algae since
nutrient maybe stuck there and feed protential algae.

What do you have in the sump?
I am not to sure if your Prizm [regular] can handle this volume.
