Hello everybody here at the forum.
We build our 250m2 schwimmteich in 2015 with help and products from Glenk here at TopTeich.
The first years we had clean water and almost no algea growth.
2017 was different - we still had crystal clear water -but the algeas was growing and growing and growing.
We kept harvesting loads of faden-algen but a few days later we could start over again. Reason? I don't know.
This year is starting to be the same as 2017.
The water is clear, but algeas keep growing -very fast and continuously.
We have a phosphat measuring device and it shows a value between 0 and 1 ppb -which means almost no phosphat for the algeas to grow of.
But why do the algeas keep on growing? What do they live of and what can we do?
Could it be a high level of Nitrat?
If so - what to do?
The water is 100% clean and fresh and visibility is several meters.
But working 10 hours per. week harvesting algeas is not fun.
All cirkulation in the pumps, hoses etc. is good and running. You can see our lake in my profile here at the forum.
Please do not hesitate to ask further questions!
We hope that some of you can point us in the right direction - we thank you so much!
