Smell??? Even fine PFS I vacuum. My kuhlis & corys don't dig much at all...TMS, black or white, is like $20 for 20lbs at the "marts". Pool sand ~$10 for 50lbs. Peace River & Eco ~$20/15lbs. Do you have carbon, it'll remove temporary smells, live plants can help...so can more water changes...
what's TMS?
