Yesterday I found out I had a RCS hitchhiker in this tank. Luckily it was still young and I was able to siphon it out of the tank. Note to self: wash plants from other tanks before using them in this tank.
I'm tempted to begin removing the tape holding the DW down. From my past experience with it, it took around 3-4 months before it was safe to do so, but that was when the DW was fully submerged.
