I want to run my impact skimmer out of the sump. I already water tested it and it does not leak. However I need to mod my skimmers return. It needs to be a little taller and longer. Will this mod mess up my water level?
If you raise the discharge it will raise the level in the skimmer. Simply raise the skimmer by placing a block of wood or a brick under it. The vertical run will not change the operation. I hope you have enough vertical room under your aquarium to raise the skimmer.
Thanks Jack. I don't think I will be able to raise the skimmer. Its a tight fit as is, however I might be able to have it run outside the tank stand. I was thinking about getting some black acrylic at homedepot and gluing "legs" or a box to the base of the skimmer. I will let you know how it turns out
