I can recommend this, Don't get a pump any larger than the recommend pump rate, not even 100gph bigger. The skimmer is rated for the amount of water it can handle to feed a pump!!! Go slightly smaller if anything. and make sure your turning over at least one total volume of water if not 1.5 times per hour. laguana seems to be one of the most highly recommend submersible pumps from most on here. (I have not used one so far) I use the pumps from Lowes. they aren't the best quality BUT, if one goes out while under warranty, they replace it, they are always in stock, I don't have to wait for one to come in a week after it goes out, and they are fairly energy effecient. The down side is, 1-2 years is about average life span, I've heard members that have the Laquana's that have lasted 5-7+years, they cost about twice as much initially but, they save money in the long haul. Kind of trade off IMO, I like knowing I can get a replacement fast if needed, Guess cause I have had to replace a few in my years from using cheap pumps.........lol
