Tristan Posted February 21, 2015 Report Share Posted February 21, 2015 I am running two tanks off of my ev20 and still not happy with the output.. I have just replaced the diaphragms hoping it would be fix my issue and while it did make it somewhat better, its still not to the standard that i want. I have 7 airlines coming from it currently... 5 go to my k1, 1 goes through my nitraguard and the last goes to an air sponge in a seperate tank. All airlines have been cut to minimum length possible. Just to give you an idea of the pressure... My sponge filter wont work when put on the bottom of an 18 inch deep awuarium... It needs to be just under the surface to get any bubbles. as far as i know there shouldnt be any issues here? Is this a warranty issue? thanks for your help Link to comment Share on other sites More sharing options...

crusty76 Posted February 21, 2015 Report Share Posted February 21, 2015 Will need to put taps or a gang valve on ur airstones in the k1 they are where the least pressure is so that's where the air is going Link to comment Share on other sites More sharing options...
