Hi, I just recently moved to a home with a small pond in western NY. Calculations put the pond at approx. 150,000 gallons and a max center depth of around 10 feet. There is drainage in and out of the pond. I spent last summer/fall cleaning out the common waste that accumulates over time and neglect. I also added the blue colorant and it seems to have helped with the reduction of new growth. The water this spring looks pretty clean all things considered. However, there doesn't appear to be too many fish in there as previous years so I'm told by the previous owner. Fridgid winters of past along with last summers drought caused the pond to drain almost 3/4 of the way (has since refilled all the way). I'm not looking to spend a fortune right away but over time I'd like to invest into it to bring life back. What are some of the first steps I should take before just dumping fish right into it? Pumps, filters, bottom feeders? Any advice and tips is appreciated. Much thanks!
