gfo inside BRS canister reactor becoming solid and appears calcified white cloudy film attached to inside walls of previously clear canister now turning opaque white? using original pump matched by BRS is the flow not strong enough? help? using separate pellet reactor w warner marine eco bak pellets change gfo every 20 days..........need solution to prevent solidification of gfo

do u dose kalk? where do u does alk/cal?

i have same problem when i does it near the pump, make sure it is dosed in high flow area and mix well b4 flowing into gfo reactor.

and of coz make sure ur cal lvl is not super high and have a balance between cal,alk,mag.

I also think that it's where you're dosing alk+cal or kalkwasser is too close to the pump feeding the gfo reactor. Or it can be you alkalinity level may be too high. But I'm leaning more towards my first impression.

I over did it when I was running two part and the alkalinity caused the gfo to turn into a rock. I noticed this white residue everywhere on the sump and pipes. Once I lowered it, it flowed freely and stopped caking.
