AEFW or Black Bugs

[Mrcote1]

I haven't though of a solution for my large colonies yet, the only signs im seeing are on my frags in a specific area of my tank. Once i start seeing the first signs on the large colonies which as mentioned before are larger than softball and very encrusted, ill probably use bone cutters to get as much off the rock as possible and dip in large bowls.

The melafix at a high dose of 5-10x for 6 minutes killed all the worms/bugs. It didnt just shock them and I confirmed by taking them and putting them in tankwater for 20 minutes and there was still no movement.

Im due for another dip tonight. Ill post results, and how many i actually used and exact times.

Also another point id like to add. Before I used the melafix, i dipped these in potassium chloride at over 5x reccomended dose. This did not phase the bugs/worms at all. I also tried coral revie (not sure how far over the dose I went but i did quite a bit). This also did not phase the bugs/worms.

The frags i did this too were dead the next day (probably between the harsh dips and the bugs overtaking them)
