Thread: Does an anoxic filter work best in darkness?

Hello all,

Does anybody know if an anoxic filter needs or works better in darkness? I’ve read a few articles that indicate nitrifying bacteria establish better in darkness but is this the case for an anoxic filter? I’m assuming the bacteria inside the biocenosis baskets are sheltered from direct sunlight so don’t need to be enclosed as such?

I currently float balls on my anoxic pond, mainly to reduce algae growth and reduce heat loss, this year I’m algae free and my Lillie’s planted with the baskets are really taking off. Ideally I’d like to take the balls out to give the Lillie’s more room to grow, which in turn will shade the filter anyway. I just don’t want to risk stumping the nitrification process coming into our main feeding season by opening it all up to direct sunlight.

Thanks all.

Harvey

Sorry just to add, it’s more the nitrite to nitrate process I’m wondering about!

Brilliant - thanks for the explanation Syd, I knew you’d have the answer
