Your miniflotor skimmer works only for a small tank. I was using the same one for my 200L tank. The performance was so so. A few months ago, I replaceed it by a turboflotor 1000 multi. It works fine to my tank.
It appears that the plastic of the skimmer is pretty sturdy. I don't see any problems with leakage of salt water onto the hardwood floor. I have hardwood floor in my apartment. Have you purchased any ihome nsurance for your apartment ?
The skimmer gains realtively good reputation among the fish hobbyists in HKG.
