Hi Tula. So I have been researching filters and pumps for about 6 months. I really didn't want to spend the money, but feel a this time I really needed to do something as I go from goldfish to Koi. I think one of the best filters are the large ones with lots of pads similar to a skippy filter but I really don't have the space. Most of my research was on bead filters. From what I understand the biggest problem with bead filters is the media clumps together so you need a blower. I ended up getting a aquadyne 4000 with a blower and an external pump that's about 4000 gph. I had to calculate my head and this size was recommended to me. My main two sources I considered were AZ ponds and webbs. They were pretty competitive with each other. I ended up going with az because I have bought from them before and they were always nice if there was a problem. This is what i bought https://www.azponds.com/product/aquadyne-filter-and-azflo-pump-combo-kits-up-to-4000-gallons/ It has all the reducers as part of the kit as I didn't want to get it and have to buy more parts.Sorry you lost your pear tree, but your new plantings sound nice. I have a UV light and use it on occasion. I'm interested to hear more about your new filter and pump
I moved my current filter from the corner and plan to put the new equipment a new cedar box to match our new fence to cover the pump and filter.
Ah I know how much you loved your pear tree and sorry it is lost. Happy to hear your fish are all doing well. My water is green also but I have too many fish. Not going to get a Uv tho. I'll just have to part w/some of the orange fish.
JW Thank you. It was really fun getting pears last year from it. When we did construction it was cut down to the stump when the cleaned the backyard of all the stuff growing and it came back to life so that was nice. Your pond looks great!
I haven't had green water since the first year but we did two no nos. My wife felt the sedges were too large so we got rid of a huge clump and I disconnected my biofilter and had to dump all the water out to move it. I typically have not used a uv light much in the past and agree the green water is a symptom and not a cause so I feel better about my decision not to get one for now.@CometKeith - have you had green water in this pond in the past? I'm not a fan of UV filtration - I know it works, but to me it works like an aspirin works to lower a fever. You're addressing the symptom, but the cause is still there. Once the "medication" wears off, the problem still remains. And I do wonder what else is getting UVd in the process.
We're seeing algae this year that we've never seen before and seeing some string algae in places we don't generally get it - I wonder if it's a combination of our hard winter plus the fact our pump was off for three months. The pond is working to regain some balance.
Cas. Yes we probably removed 50% of the plants so that could definitely be the cause. My wife is very involved in our backyard pond design and she felt it was too much.
Here is a pic I took this morning. You can see some of the new plantings we did behind the pond including arbor vitae and succulents and
it is sans the pear tree in front. I planted some grasses there. Our yard definitely feel larger now without it. Also we are getting more sun without it but the new fence is blocking the morning sun so it's hard to know how things are affecting the pond when there are so many variables!
