Reef safe cement/concrete?

[Paul B]

I know of that product, I just never knew if it was reef safe as it has more ingredients in it then regular cement. But if it works in a reef, I may switch to it

Wound up just buying plugs bulk online. Has anyone used oceans wonders frag mag

 

[MatteZ]

I use ocean wonders all the time. I buy them off eBay 100 at a time for like $20. Never had a problem. I just keep a handful in my sump all the time.

I seem they had advertised that they were already cured but I threw a fistfull in the sump also. Now has anyone had any experience with the magnetic discs

 

[MatteZ]

I just keep them in the sump to wash the dust off and stay hydrated.
