LF: Cheap Instant Ocean Salt

[AquaAddict]

I have been using H20 salt for a few years and my 20 gal garbage can also has a coating but it's not very thick. I never thought it was a problem. I use to rinse briefly with fresh water but I don't even bother doing that any more.

If this is some kind of organic sludge, what stays in the water mix and ends up in the aquarium?

I always have an algae problem and have to use Io nitrate reducer and also dose with Brightwell Reef Bio Fuel to keep it under control. Yes bio lode is low: 5 small fish, 1 medium in 100 gallons, 20 gal sump because nothing bigger will fit under a corner tank.
