Best Bio-Block

[nycfishy]

Any recommendations for bio block that wont disintegrate? My current one is turning into mush. Now granted it's sitting under my skimmer so that might be contributing but looking for something that will last a more than a few months. Specifically looking for block.
thanks in advance

maxaspect blocks seem to be something that might hold up, anyone have any experience with them?

I had 2 melt on me. They also were under my skimmer. I think the vibration of the skimmer causes them to fall apart. I switched to putting bio balls in my refugium.
