Lowest cost and easiest way to eliminate green hair, bubble, turf and slime algae

Dark Slime and Black Slime - what it looks like

Here are some examples of dark slime, and black slime. Usually slime it starts on new scrubbers which have high measurable nutrients in the water, or on small scrubbers on big tanks with lots of rock where the scrubber is not big enough to pull the nutrients out fast enough.

Notice that some of them have white patches; this is because the slime let go and floated away, leaving white surfaces behind.

In all cases, just take it to your sink and toothbrush them (without toothpaste) so that you can see the white surfaces again.

 

"Algae scrubbers are one of the few, if not the only, nutrient removal systems that give me something back: Growth. It's a no brainer" -- Jim Stime, LA Fishguys

"I see algae scrubbers as the single most significant nutrient exporter you can have" -- Stephen Babcock, The Corner Reef, Columbia, Illinois, USA

"I am very happy with my [upflow scrubber] which is working great. I will be [using] more scrubbers for my other 8 tanks" -- Bruce Ashcraft

"The [floating upflow scrubber] is really useful and highly necessary for my tank. So I really can't be without it for too long" -- Jason Pappin

"My [tiny upflow scrubber] works great, and I was thinking about another one. The biggest difference I seen was my phosphate level went from 0.11 to 0.03-0.06 range " -- venom on the CR site:




"The [upflow scrubber] is producing lots of lovely green algae for me" -- K19RKS on the UR site.

"Growth from our [upflow scrubber]" -- Alyse Fisher:



"Tank is heavily fed and [upflow scrubber] definitely seems to have made an improvement since the algae started growing" -- Jason Oneppo

"[floating scrubber is] growing very well. Love the in sump design. Will probably do another down the road as I increase my bioload." -- Erik Sulman

"I'm getting good results from my [2 upflow scrubbers].. It's bringing my phosphate down and starting to get some decent hair algae my tangs love" -- Dane Wilcox

"WOW! 173grams. Two weeks growth [on the floating scrubber]. We LOVE it! The growth rate of the chaeto in our refugium had been steadily decreasing over the past six weeks or so. Yesterday, it became obvious that the chaeto had started to melt/die-off and needed to be removed from the system" -- Mike&Terry on the R2R site:




"There is getting to be some nice looking green hair algae in it" -- Dane Wilcox

"I clean my [scrubber] once a week. Definitely helped lower my nitrates." -- Nagrom on the MR site

"I installed a [upflow] ATS in my 3rd chamber with the return pump in my 29 biocube works well for me. My nitrates stay between 5 ppm or lower. Phosphates are usually .04 or lower -- Saltyphish on the R2R site"

"I didn't really expect much from the [upflow scrubber] and put it in my sump. After about 3 weeks the algae was in abundance and now I have to clean it every 2 weeks" -- Jukeboxjury on the RF site.

"The [upflow scrubber] is doing really great. The first time it was full of green small rounded shape of algae, feels like jelly, i dont know what that is. The second and third week after that is full of green hair algae. Water parameters are great, with readings from hanna checker and salifert testers" -- Yuppy Suhandinata:






"The scrubber is working great! getting a lot of nice growth" -- Mike Buechs

"I installed a [small upflow scrubber] in my 3rd chamber with the return pump in my 29 biocube, works well for me. My nitrates stay between 5 ppm or lower. Phosphates are usually .04 or lower" -- Saltyphish on the R2R site.
