sea lab 28


New member
Just wondering if anyone out there has used sea labs 28 tablets in their reef systems and what everyone thinks of them i have heard alot of good things but ive also heard some reasonable arguments against using them they have been around for quite a while so has anyone used them long term? and how well did they work ?

Very old school; It is nothing like it claims. All it does is slowly dissolve and release stuff, whether your tank needs it or not. Used back in the day because we didn't have good test kits.

It's best to dose what you need calcium, etc
