Hi Cecil, If you have the 2005 Aquatic Eco System Master Cat look on page 255 The Sweetwater SL 94 is rated 15 ft depth,90 watts and 4.2 CFM for $380.00 Their toll free is 1-877-347-4788 if you need a cat. They have an online store also. Give them a call with your situation as they know linear pumps very well.I dont think you will have a problem with your described situation.Tech support is 407-886-3939 Apopka Fl Bob Heideman > President The Gast 0523 comparison today is the same CFM as before but still in the 4.2 amp range so a linear will run for less.The 0523 can be had for the $245.00 range low or high volt. Take care Ted
