skimmer question

[fencer]

I am currently using a 220 on a 72g( total system vol 125 g). I have no complaints. I don't dispute there are better skimmers(You get what you can afford and make use of what you got). All skimmers are affected by the level of the sump or the tank. Fill the sump with makeup water you affect the balance of the skimmer temporarily...which can cause flooding. Wet skimming can lead to flooding. You can improve the skimming in the 220's by adding a beckett mod or adding fishing line to the impeller or adding a recycle loop.
