Hi all...I posted my pond in the showcase but forgot to put any info about it. The pond was built by myself with a little help digging from my brother in law (he opted for a nap after lunchtime pizza arrived on dig Day). It is almost 3 feet deep and I estimate it is about 1400 gallons. I have 10 koi, 2 shubunkins, and about 6 comets (I know it’s overstocked but try to keep up with the water quality). The comets were born in the pond and I believe the eggs came in on a plant i purchased. I use the Laguna pressure flo filter and submersible pump but if I had to go back I would totally do a bottom drain and external pump setup with a catch skimmer. I had one horrific year with string algae but found algaway 5.4 very effective at keeping the pond free of string algae after I cleaned it thoroughly. I changed my whole waterfall recently and opted for the aquascape spillway. I found that having the return from the filter to the spillway didn’t give me the desired amount of water going to the waterfall so I opted to put the pump directly to the spill way and put a second pump in for the filter with a return directly back to the pond. I had luck my first 3 years with my Lilly’s wintering over but not so much these past two years. I’ve lurked on the site for a few years and love seeing pics of other people’s projects!
