NP pellets and bleaching events

[The Grizz]

It boggles my mind as well, so I have been thinking of things that could contribute to this but it's only speculation.

I know that Kien runs pellets in conjunction with Carbon & GFO but not sure what he has for a skimmer or what its rated for. Also how much flow he has running threw the pellets and threw his sump and has no issues.

I am running pellets with double the req. flow with an Aqua Medic 2500 pump, Carbon & GFO. My skimmer is rated for 400gph, feed by another AM 2500 & recirculating with the same. For flow I have a 3600 GPH closed loop and a 6500 GPH return pump.

So I am wondering if there is some connection with the way people's tanks are run because no tank is the same. For those having issues let get some info together on each others system to compare and see if we can find a connection.

Just a thought.
