Good Morning,
We moved into our house in February and today had our first dead fish
. I immediately tested the water (drops) and the levels are fine besides Phosphate which is high (5). Ammonia 0, Nitrate 0, Ph 7.
We added sludge destroyer because that’s what the water test instructions said.
Normally the Phosphate was around 2.
Things that happened: lots of rain over the summer, storm yesterday with lightning and rain. We are in zone 7.
We feed 1x day what they eat in about 2-3 min (8-10 hand fulls of pellets).
What should I do to lower the Phosphate? We are planning to clean / cut back the plants soon for winter. They are still green. Should we do it now or wait?
The bottom of the 4500 GAL pond is filled with stones, we have one waterfall and one pressure filter w UV-pump is at bottom of pond, 2 airators and a skimmer w prefilter and pump that feeds into waterfall (w filter and bioballs and lava rock).
We clean the prefilter every 2 days and waterfall weekly to every 2 weeks.
We have a lot of larger Koi and they had babies in the summer that are a few inches only.
The fish that died was about 12 inches and did not look injured. Not sure how old.
Thank you for your help!
Regina
