Anyone know of a reef safe, preferably easily available at home depot or lowes, plastic dip for magnets? I would love to make my own frag mags and use them for other in-tank reef applications. Thanks in advance.

Having run two previous successful tests on algae patches in my tank and having no negative results to date, I thought I share the process.

I used the following-

1 cap full of peroxide
1/2 tsp baking soda
Baby medicine eye dropper
Small plastic dosing cup
Turkey baster

Mix the peroxide and baking soda together in a small cup and mix until the baking soda is dissolved but viscous. Suck up into the eye dropper about 1ml of the mixture. ...
