I want to ask suggestion if this marine pure worth of buying or just a hype and no evidence of benefit on the reef tank. I watched the BRS investigate section of marine pure comparison but at the end of the result was the same thing with marine pure vs without marine pure other than water clarity vs to tank without the marine pure. Hope you could help me to decide. Thank in advamce

I had two of the large marine pure blocks in my tank. One in the sump and in in the display. In my experience they definitely break down. They’re brittle to start with and with time get to a point where even when you touch them they crumble (I’m talking about a few months). After about a year I had enough and went with all rock.

After using both the brightwell block and marine pure products. I would go with brightwell, marine just too brittle. I've used a few variations of what marine pure offers and some of them started to crumble after the initial rinse. As for results with blocks vs no blocks, I would say that they have not shown a significant difference in my tank. I feel the only real benefit is extra area for bacteria and pods to grow.
