Used Bionic for a bit then switched to tropic marin balling salts . I then switched to Eco-System balling salts since I couldn't find the TM anymore . It was way cheaper @ 25.00 for 3x1 gallon mix powders . I plan on going back to it and dosing it by hand .

What he said. Doesn't get much easier. Their 1 gallon packaging and reef additive calculator make it pretty much bullet proof.
