I must be one of the lucky ones, I bought the Seaclone 100 before I found out about its bad reputation on line. I decided that I would give it a try. I have the "Cant pass up a challenge" gene. I installed it on my new 30 gallon tank Sunday night and just tweaked it a little every night until last night (Wednesday). After letting it sit for an hour after making the final adjustment I now have a nice column of steady foam. This morning there was about an 1/8 inch of gunk in the collection cup and the foam column was still present. No micro bubble in the tank and it is puring along nicely. I have never used one before and I really don't understand all the fuss. Maybe other skimmers are set right out of the box, but this was what I had on had at the time. As long as it keeps working I am happy with it. My only ***** is the weak suction cups that came with it. They don't hold very well and I will need to find replacements.
Will this continue? I don't know, but I will take it for now.
Its not absolutely quiet, I hear the burbling, but I don't know any way to make it stop without causing it to not function. If you want quiet you may have to sump it and insulate the area around the sump for noise.
