I carbon dose with vinegar, use a small amount of gfo, and have a RDSB in my fuge. At this point I'm sure the sand could go bye bye without any ill effects on the system. However, for now it is staying in place simply as a place for small critters to grow and do their thing. I'm hoping that at the very least it is beneficial in this regard. Otherwise, I will be removing the sand bed and just running macros and maybe some seachem pond matrix as a LR rubble substitute
