Mr Aqua OHF and Algae

[apisto31]

Hi Bros,

I just setup an additional 4ft Mr Aqua stackable filter (6 trays) on my 422, this an addition to my existing canister filter. I just noticed that since it's beside my 4X54W light, there's a strong amount of light going in to the OHF (since it's a clear plastic). Im pretty sure that there will be algae there sooner or later. Anybody care to share your experience on this? Will it be a good idea to cover the side of the tray with oyama to avoid light from going in, can it withstand the heat from the light? Or any other method to prevent the algae build up on the ohf trays?

Thanks in advance!

There is no way to prevent algae buildup on your trays. If they are exposed to the air, with a source of moisture and light, over time, some algae will grow on it. I have green and brown algae growing on my output tubes from my overhead filter trays. It doesn't bother me much, but if you dislike it, clean the trays often.

Thanks Bro.. What you said is true. I've decided to cover the Base and the bottom layer trays with black oyama at least to minimize the algae growth and for aesthetic purposes as well. Cheers..
