+1 I have an old 50-250 Red sea Berlin skimmer I picked up for $5 been thinking about running it on one of my FW tanks but I wasn't sure which one it would be most effective. I have some messy NW monsters in soft water but I also have a ton of Africans in extremely hard water.....
IME they work better with harder water.

I should really read the article Joe posted, but I thought protein skimmers wouldn't run on fw tanks?

Very much south..
A theme i think about every now and then....would love to use it in my sw tanks with the tons my guys eat....

And your pix show it working.

I know Duane's been using it, but one needs to be an engineer to mount his system :)

Don't mention this to my engineer friends, they would be insulted, as I am far from being an engineer.
IMO used in conjunction with biofiltration, it is the best filtration method available.
I did tests in the lab, and found along with DOCs, it removes freefloating algae, and some parasites in the planktonic stage. It also removes heavy metals, and medications (should be turned off during treatments)
Protein skimmers are actually fairly simple, they just take some tweeking, and a bit more flow than most aquarists are used to providing.
My DIY one came from plans on koiphen.com, and is also a biofilter, because of the lava rock media used to create cascading agitation.


Below I compared fractionation waste with normal tankwater.
Fractionation removed 8-10 times the dry waste in a similar aliquot of tank water.
And although I didn't get microsopic photos, the removal of bacteria, and other protozoans presented a similar comparison.

1) Duanes, do you add salt to your water? Is your water hard?

2) Catfishguy, have you tried less salt but found that this was the correct amount, or did you start with that and kept it because it worked?


I'm impressed by what both have posted and starting to think that this is a good idea. I just want to know if there are factors I'm missing.

I do not add salt, and my water is neutral as far as hardness goes (7 grains/250ppm)
pH hovers around 7.5, alkalinity betweem 60 -100ppm.
I first heard about protein skimming in an old TFH article by Joe Gargas, he was using fractionation in a discus hatchery, with very soft water.
