Bio Pellets - High N Low P

[Metrontech]

Thanks for the reply

I am running a 120 with a 5 sump

Reef Octopus 150 skimmer in sump. BP reactor is pointed directly to the skimmer and getting good skimate

Chaeto and Aqua Carbon 2.0

I realize the BP don't remove much phosphates, hence the post...

I have added 3 rounds of Bio Clean (same idea as the microbac 7)

I am assuming the phosphates have dropped with the water changes and cleanup of the sump...

BP are tumbling and not sticking, never had that trouble...

Anyone else chime in?

Another suggestion that I can put forward is that you may want to dose microbacter 7 while running biopellets to make sure that good bacteria grow and bad ones (e.g. cyano) doesn't start consuming the carbons.

You may want to include some more info (tank size, are the biopellets tumbling properly, type of tank, is the output of the reactor near or plumbed to the skimmer, etc.).
