fresh water skimmer
 

just curious: does a skimmer work in fresh water setups? i know in saltwater, it bubbles easier but cant you just raise the water level in freshwater and have it work?

wont work...

nope
 

-used 2 think about the same thing but...honestly skimmers are rendered
virtually useless for freshwater! -wouldn't try but hey w/e and good luk//

Seems yes, in large scale FW systems, search for foam fractionator or foam fractionation.

For fish farms (note under features, different cone)

Koi ponds

it can work but it is very hard to set up properly.

-what makes skimming so ackward in freshwater again i forgot is it that
freshwater has no specific gravity or the water chemistry in general?

salt water has a higher surface tension which makes it hold the bubbles better.

For 10$ I purchased one of those surface skimmers that hook up to a canister filter. Within 10 minutes the surface was crystal clear. Totally underrated in my opinion. I tested it in my reef tank and the skimmer is definitely skimming less with that on so I moved it to my discus tank.. Inexpensive piece of hardware.

i was looking for a skimmer for my new discus tank but had problems finding one so i settled for a fluval fx5.

Yes this thing works really well in fresh water.
However it is Very sencible to level fluctuations, algae will grow inside, it only works when super clean and with constant water level. I had one too. Now garbage bin has it.
waste of money imo.
