I have a reef octopus 110 its running in about 7inches of water. The skimmate that it makes is alittle bit in the cup. Alot of the matter gets caught in the cone or tube of the skimmer. If i raise the water lvl inside of the skimmer the skimmer will not create a thick foam head. So i dont know which is better to have a thick foamhead and collect all te stuff in the tube or high water lvl in skimmer and .... idk what will happen? thanks
