This tank is for my Betta, it contains 2 large driftwood pieces and many plants, moss ball, java ferns and crypts. also anubias. I am doing 50% water changes weekly and dosing ferts as recommended and using excel daily. Still have particles in clear water. Tank is a Solo with LED lighting. Filter internal and wondering if i should 86 that charcoal bag in lieu of matrix beads and place Purigen bag in the tank under the outflow. I dose macros on separate days than Flourish and Trace. My Betta got fin rot in there so he is in paraguard therapy in a hospital tank. He is perky, eats, not sluggish, nor constipated. I don't want to put him back in his tank until color returns to his tail. Would like to get rid of the particles without using a clarifier which damages Betta labyrinth systems. (My last one suffocated and everything turned brown. Can you help? Do I need a new Danner 210 filter? (His name is Brutus and is a red & blue half moon)
