hi guys just wondered how do i set this product up for use in my marine tank its a juwel rio 400 how do i know the rate what to feed it in to the tank,

ps i was on the forum but not been on for months and this was my previous login name

use it in conjunction with your skimer,have it controlled by an mv controller so you dont over dose,or put it on a timer and run it for an hour-two hours a day.hth regards mikk
p.s set the controller to roughly 350-450mvs

ok thanks for the information appriciate it
