Hi guys, I want to tidy up my po4 level as my gfo maintains it but not reduce it a great deal, so ive seen Larrys dosing calc (great work) now i dont have filter socks so would i be best to to drop it straight into the skimmer neck? my plan is to add 1/2 dose spread over week 1 3/4 dose over week 2 and full dose on week 3 testing as i go............. does that sound like a plan? many thanks
