Pond Construction & Filtration / Re: Pond Skimmer and Pump Problems - Help!

« on: July 03, 2010, 06:37:46 PM »

thanks for the response guys. i talked with a guy this afternoon here in town (river city koi), and it looks like my skimmer is too small for my pump. i pulled the pump out, and it's a 3360 GPH pump with a 7' head. it's a stainless tsunami, i believe. so i have a great pump, and a small skimmer. their recommendation is to buy a larger skimmer. a big bahama, i believe.

in the meantime, i have decided to put a good bio media in the skimmer, and i put my mechanical sheet filter material in the waterfall above. putting the filter material in the waterfall also helps regulate the amount of water flowing through that big pump.

so far, so good. the skimmer is staying full, and it looks like a lot of debris is being caught by the filters in the waterfall. i know it's kinda bass akwards, but i'll just have to see how it does.

what do you guys think?is this a solution that might work?

thanks again for the input. aaron.

Pond Construction & Filtration / Pond Skimmer and Pump Problems - Help!

« on: July 03, 2010, 06:56:07 AM »

hello all. my wife and i recently bought a new house that has a large (2500 gallon) koi pond in the back yard. we absolutely LOVE it, but we've recently started having some problems with it. i was hoping someone here could help me out. here's what is going on...

my pond has a skimmer with a pump in it. the pump pushes water up to a waterfall about 30 feet away. lately, the skimmer has not been staying full, and the pump is pumping lots of air with the water in the bottom of the skimmer. the koi pond is plenty full of water, but it just seems like the pump is pumping faster than the skimmer can supply water. what could be going on?

another quick question: my pond is dirty, and i want to filter the water. my skimmer doesn't have a place for the filter material, and i want to put a bio filter into the waterfall. can i just stuff filter material in and around the inside of my skimmer, around the pump?

thanks so much for reading through this. kind regards, aaron.
