I use a mangrove 6 to stay on top of the acrylic. I use a dozer pad with it to help get hard spots off. But I have heard of ppl using credit cards with no issues.
I was testing a prototype reactor for geo of a newish design. I have some lps and a few SPS in the tank and more coming is another reason I was using it. More than anything to test out some changes of him and by time I had it all dialed in I would have more coral needing it. Heading towards more coral now.
Worm, no I do not have the WXM for the apex, but I'm looking for one. That way I can program my mp40's pretty easy.
