I jus built a modified sump tank. I have my 120 gallon tank upstairs and I made a 50 gallon sump and I have that downstairs. I have my skimmer and sterilizer and phosphate reactor all downstairs my new sump is 30” long and 30” high and my skimmer sits about 14” off the bottom and hasn’t been collecting so much lately. Should it be lower in my sump? Also. Can I buy a bigger pump for my skimmer and drop it down and pump it up the 14” to my skimmer
