trying to get rid of algae....

... hello again. I have a reservoir that's 18 gallons. A light grey colored plastic storage bin that i got at walmart. I am doing a bubble system (not top-fed). I change the reservoir water every week. Ive been noticing algae gathering on the air tubing. I think its green algae. I rubbed it between my thumb and fore-finger it was slimy. I was wondering is this because of light mixing with nutrients in the res. So should I spray paint the outside of my reservoir black? will that help me get rid of the algae?

Light proof your system.

Spraying it black will increase it's ability to absorb heat. You want a cool reservoir ideally. Buy yourself a roll of aluminium tape. stuff works wonders

...^^yup and for the interim; 1/4 tsp of bleach....unless you are all organic-n--shit or you go live res...

pond zyme has been getting a lot of buzz lately

Hydrogen Peroxide, Give it a try!

Light-proof = no algae. Light-proof = cooler reservoir. Cooler reservoir = more dissolved oxygen. More dissolved oxygen = less problems with any pathogens and better plant growth. Insulate and light-proof your reservoir, too many benefits in doing so and too many problems if you don't.
