Here is my review thread on the block...

PH stayed pretty constant... I never tested alk, magnesium was off the charts. Correct on the block dissolving based on flow around it. Not sure how they can claim it dissolves based on tank demand. For large 100g plus systems I would use the block...for smaller systems such as my nano... I will use the small mini blocks. I like it and will continue to use the block. Prior to the block I used to use fiji gold powder. I like things that I cannot overdose. I'm so scared to crash my systems from my own error, this hobby is challenging enough without all my mistakes.
