I am using 2lbs in freshwater for Al40's and 4lbs for Al80's.
Since I use a tank strap on the bottom of the tank I thread it through there. It does scar the tank. I was thinking of moving to Diverite weight/trim pockets for vacationing and moving in between different tanks.
Some people like a certain amount of lift to show the tank is empty- not myself.
I would be interested in any pictures.
Is this turning into a low profile- Optima.
