biofilm problems

clau74 · 01-11-2013, 12:39 PM

Hi,
I know this topic has been discussed many times, why is biofilm in a tank?
If there is a link between phosphate and biofilm?

BruceF · 01-11-2013, 02:14 PM

Are you talking about the surface of the water?

clau74 · 01-11-2013, 02:31 PM

Yes, biofilm on the surface.

Darkblade48 · 01-11-2013, 09:18 PM

From what I recall, the biofilm on the surface of the water is generally proteinaceous in nature, so it probably comes from fish food, and not phosphates.

Various protein skimmer assemblies (salt water people use these), put the output of the filter at the surface temporarily, paper towels

We all deal with it from time to time. It usually happens the day or two before a water change and I put the filter output at water level when the lights go out (not to vent CO2) and it reincorporates it into the water - the next day a w/c does away with it

Hi ,
Thanks for the replies, excess protein is the main problem?

danielt · 01-12-2013, 08:07 AM

Yes, excess food. I have the biofilm disappearing by itself if I don't feed the fish for a couple of days. I don't skim the water surface at all. I don't see a point in doing that.

Feed less and often than once in bulk. If you can't, invest in an automatic feeder.

Cheers!

Daniel has it right. usually too much food causes it.

Excess protein in food is shrimp believe.

danielt · 01-12-2013, 09:43 AM

Shrimp, krill, fish meat. Any meat put in the food mix. Don't know about vegetable protein though. I'm thinking of soy protein.

once about 2 years ago on a asian aquarium site i had see a diy made from a cheapo micro internal filter upsidedown (inlet up outlet down :P )put inside a grided cut inlet pipe... and now for a while i see amano's vuppathing ...deja vu? Lol

Cheers!

sadly that does not always work. i have a tank that i feed once or twice a week and i still have have biofilm, the amount of food that i feed is minimal because the fish is rarely out for food. of my 5 tanks 3 have biofilm, really its only of 4 tanks because one has a surface skimmer.

the best "cure" to biofilm is surface agitation, or a surface skimmer.

Air stone on a timer, 30 minutes a day, best when the CO2 is off. Cured.

Thanks for the reply, if a pump wave supplement may be the solution?
