Ok I have both sides of my tank full of the red slim on the sand,
I tested my water and these are my readings
Ammonia 0
Nitrate 0
Nitrites 0
PH 8.0-8.4
Salinity 1022
What the heck is causing this red slime :mad: :mad: :mad:

A few things can contribute....dead spots in your circulation(I keep 3 maxi-jet 1200's low behind my rocks to eliminate dead spots)...excess nutrients(if you run a skimmer how well does it work?)...phosphates can contribute(is your top-off water free of phosphates...if phosphates are measureable maybe run a good phosphate sponge)...lighting out of spectrum can contribute(when were your lights changed last?)...excessive feeding(cut back for a while and see if it helps)....also try running a quality carbon for a few days to help clear your water up and maybe remove disolved organics that may add to your problem.
Normally its a combination of factors but with persistance and patience you can eliminate the problem.:cool:

I struggled with red slime for a long time...I finally broke down and got an r/o unit and I haven't seen it since. If you use a phosphate sponge you can starve the stuff to death.

i had a problem with red slime as well... mine was caused by overfeeding of the neigborhood fish-sitter. Where the algae accumulated most was behind the live rock, where the circulation was at a standstill

Circulation and Phosphates. I'd say just do a water change with RO/DI water and add a powerhead or two. It should fix the problem. I had the same deal a few years ago.

I used "Maracyn" once to kill the red algae and it worked great. Within two days it was gone. The problem was I did not solve the problem... I covered it up. Withen a week I had an outbreak of green hair algae. The hair algae covered the tank quite quickly.
My point is, there are chemicals or antibiotics that may remove the red algae but they do not solve the problem.

I'm currently battling this problem too. I'm sure circulation isn't my problem because it builds up right on the return outflow. I might try a phosphate sponge and a couple big water changes.

Had a massive red algae overrun of my tank about a year ago. I tried to fan it away with my hand and let the overflow get it. That was about like a turn in the punch bowl. Then tried removers for it. Then I invested in an ass of snails and hermits. Finally I stopped asking normal people and ask the old fart at the LFS and he told me to mix about 25 gallons of water and fan like I was let let the overflow get what it could and change 5 gallons about every 4 hours. That was in a 55 gallon. I figured what did I have to lose and tried it. I started into it late on sunday night and got piss drunk waiting on that 4 hours, woke up hating beer, fish, algae and hangovers on monday and finished what I started. Monday night when I came home from work tank was dark as usual and I was worn out and didn't look. Tuesday I woke up and had minor traces of it but that was gone in hours and never came back.
I would suggest giving the old fart method a try was cheap to just use hand to fan it off and do water changes...

I was battling red slime for a while. I think my skimmer sucks (CPR) because I very rarely have to empty the collector. I decided to go the refugium route to have the macro outcompete the slime by consuming the excess nutrients.
End result: my macro's are growing quickly and the red slime has disappeared in less than a month. Nothing like doing things the natural way.

sucram, I can't agree with ya on the crp sucks. I have been upmost enjoyed by all my CPR toys. My overflow is as close to silent as I have heard from any tank. Makes less noise than my friend's drilled corner overflows. My sump/skimmer is great and skimmer dumps a bunch of gook out. Viewing your page also and your tank looks really nice.

Thanks shep.
I actually like my CPR stuff, I have an overflow and skimmer from them both are very quiet, but I feel my skimmer should be pulling out more crud. After a couple years of running, I started getting red slime and had a flatworm outbreak - both signs of excess nutrients. I am still running it, but hopefully my refugium will do a better job.

Squishy... It does work, the problem is it doesn't remove what ever is causing the red algae in the first place. In my case, at the time I was using tap water and have a phosphate problem. It removed the red algae but did nothing to remove the phosphates...
