So I bought this Etss 1700 Skimmer a couple of months ago and just wanted to know if anyone knows where I can find specifications on this skimmer because this skimmer needs bio balls in the downdraft tubing and I need to know how many I put in there to be most efficient?? and or if your familiar with this skimmer how has it worked for you?? I have a iwaki 100rlxt that will be running this skimmer!! Thanks for your help!!
