I'm hoping someone has already done the math, but I'm currently putting phyto into my tank weekly while leaving the roller mat operational. I turn off the skimmer for a few hours, however. I imagine SOME of the phyto is filtered out, but my understanding is the Red Sea roller mat is about 200 microns, meaning a lot of the phyto would get through until it clumps.
Am I throwing away phyto at this point by letting it run through the sump? If it means turning off the return for a while when dosing, that's fine, but it's just one more thing to do
