“I have changed all my filters to OASE 350 THERMO
I have regularly cleaned prefilter every week for 5 months approx 5 minutes work
Opened canister first time today slight mulm film on bottom sponge all others like new.
Cannot believe how much time and work they have saved me. I have two on a Rio 400 and two on a Vision 450. Original JUWEL internal filters removed to much continual work and buying new media.
The Oase work great and save me so much time and expense
Both tanks have large sponge over intakes which also helps .”
