Hi,

Should I use the canister filter model, I plan to WC max 50% to reduce change to the existing water hence reduce stress and affect on the ranchus. I may include UV to get clear water.

BTW today I lost 1 of my tosai under quaranteen (the white-red pc). 3 others are continue under quaranteen.

I don't practice checking water, maybe thats my biggest weakness.

Cheers,
