rowa

If you have an open top reactor similar to my Ultra reef reactor and want to use Rowa media then there is no need to rinse the Rowa before putting it in the reactor. I simply put the required amount of Rowa in the reactor and put some filter mat over the top and secure with an elastic band round...

The amount to add of ROWAPHOS is pretty hard to tie down, various articles give different advice. Does the amount added directly follow the rate of removal? ie If you add twice as much will the levels reduce twice as fast or will it just take longer to deplete?
