Thinking about trying Biopellets..

[dRsLy09]

I recently started having an algae issue and so I'm considering a biopellet reactor. Please let me know what you think! My tank has been running for almost 2 years now, and this is the first time I've encountered this problem. My setup:

75 gallons
6 bulb AquaticLife t5 fixture
Remora Pro hang on back skimmer
2 MP40's
reactor running GFO
" " carbon

This nasty slime algae comes within a day or 2 after getting rid of it (manually) and doing water changes (weekly). I've tested for nitrate and phosphate, which both say zero! I'm assuming I MUST have some just based on the tank's appearance.

I'd like to try biopellets- Is my Remora skimmer good enough? Do I need to stop running the GFO if I start pellets?

Any input will be much appreciated!

I started using pellets and took off my carbon and gfo and just use the bio pellets. They work really good the only issue is the water will get cloudy for a couple days then it goes away

Sean,

what test kits are you using. From the fotos, you clearly have some nutrients available. Bio-Pellets are especially efficient at NO3 reduction, but do remove PO4, as well. A real advantage is that one can't really OD on them, as they are not dissolved, rather digested by the bacteria. Sort of an open smorgesbord waiting for the bacteria. ODing carbon (vodka and other liquid sources) has recently become associated with STN/RTN issues. This shouldn't happen with Bio-Pellets.

As to the skimmer, I have no experience with this model and it may not be efficient enough in the long run. As most skimmers are over-rated as to capacity, I recommend one that will handle twice your tank volume at least. You are aiming for a ULNS effect, which many skimmers will not handle at their rated gal/ltr capacity. If you have a sump, the most efficient skimmers are mainly in the cone variety, although most will swear by their Bubble King's! This is a piece of equipment one shouldn't skimp with.

You don't want to run GFO with pellets, or only a small amount if PO4 becomes an issue.
