Hello and welcome!
Tell us more about your pond......and pictures are great if you have any you can share. Sometimes those can tell us more than a description can.
Answering these will get us started........
- how deep is it;
- what are the dimensions
- is it a liner or concrete [do they even make pre-forms that size....?]
- what kind of filtration do you have;
- what size is your pump;
- how many and what size are your koi;
- do you add anything to your pond such as chemicals or products to remove algae, sludge, etc.
- do you have city water or a well -- and if city water, do you use a dechlorinator
- do you do water changes
- do you have rocks or gravel on the pond bottom
- do you have a bottom drain
- do you have a skimmer
- do you use supplemental aeration;
- do you routinely test your water and what kind of readings do you get -- we ask for the actual numbers, though, not "water is fine"
- how often do you feed
- is the pond in full sun or is there some shade
- do you have any plants
- do you quarantine new fish
- is the pond built up enough that there is no run-off from your yard into the pond
- describe your "love-hate relationship"
- ....and that's all I can think of off the top of my head.....
Your pond is twice the size of mine with a different filtration set up. I run a medium size submersible box filter with bio balls and a pre filter pad at 1050 GPh. I don't think I'm the one to help with your system. But understand claririty isn't the only thing to think of.This was my forum question.
I installed the pond last year and have had nothing but problems. My koi do fantastic, but my water, pump, and filtration are driving me insane. What type of pump and filtration do you recommend? I am currently using a swimming pool pump to draw the water and run it through my filtration. I have a milk crate wrapped in netting that the hose goes into under the water. It then runs through the small filtration basket, and out into my filtration bin. Then the water goes back into the pond relatively clear. I am also using Aquascape granular algaecide, which has helped tremendously. Over the course of this ponds life (16 months!), I have used a large sump pump to draw water, and 2 pool pumps. They have all burned up. I just read someones post saying they have had their pump for 25 years! Please help me keep my sanity and point me in the right direction.
Although Hayward is an excellent brand swimming pool pump, it is not constructed to run 24/7/365. A true Pond pump is needed here.
Need photos of your pre-filter and filter before any comment/suggestion can be made on their effectiveness.
Cease using any algaecides or other chemical/biological treatments. These are absolutely unnecessary in a pond with proper fish load, filtration and water flow.
All of us here on this Forum will help you in realizing a balanced pond that is a Joy and not a worrisome 'Money Pit'.
Best to take things one step at a time.
Welcome to our group! I stuck with shubunkins no koi, just filter my system with a huge bog. The filter users will help you out with how to get your pond working better.
