Why won't this GO AWAY!

  • We are currently upgrading MFK. thanks! -neo
Personally, I dont like using meds (especially antibiotics) unless all other viable options have been exhausted. Looks like green mat algae to me as well and I really think cleaning and reducing light will be the best solution. Ive used Maracyn and Maracyn 2 in the past and it can help for particularly stubborn infections, but i think I dont think its really needed here...and its not cheap either. Just my 2c
 
Now when you say cleaning, do you just mean vacuuming the substrate, scraping tank walls, and performing filter maintenance? Because I can't actually empty the tank and give it a good scrubbing...nowhere to put these fish.

Good gravel vac and removal of as much as you can by hand or siphon. You dont need to empty the whole tank.

Alright, the cleaning/lighting tweeks will be plan A, and if that isn't helping after a couple of weeks I'll look into some of the meds.

Thanks for all of the help!
 
It is most definitely cyanobacteria.




Acs - how old are your lights?
 
Ahhh.. I hate algae... it turns a beautiful tank into a slimy mess overnight. I'm currently dealing with a huge brown algae problem, spent 4 hours cleaning the tank today. No sunlight, 0 ammonia, 0 nitrites, nitrates below 5 ppm, plants doing well, a bunch of otocinclus, nerite snails, apple snails, added phos-ban and clearmax to all the filters... nothing works, it just grows from nowhere, faster than anything can eat it... I guess I'll just have to wait until it leaves on its own.

Usually I run my lights 8 hours, but for a time I cut back to about 4 hours per day. I've never tested for phosphates in my tank but I keep my nitrates low, so I don't believe that's the problem. I'll have to look into a test kit for phosphates.

yes phosphate will be a problem even without nitrate , its a real pain for reef keepers because of the high amount of light used .... i have 150 watts of light over my tank and never have an algae problem because i always have floating plants . i find the best to be water lettuce because it never gets eaten by anything and grows like mad.
 
I doubt it would help, not with the length of time that you run them, and only being 5 months old.

Changing old tubes can help though. It pretty much cleaned up a cyano outbreak I had several yrs ago when running 2 yr old lights.

Cyanobacteria occur in an aquarium when there is an excess nutrient load (nitrogen) and an abundance of light. Algae colonies, in general, grows at wavelengths between 660 to 700 nanometers. Cyanobacteria is known to grow at much shorter wavelengths between 530-620 nanometers. Old bulbs and lamps will produce the lower wavelengths that will foster Cyanobacteria blooms.
