Having recently built our first pond,3000 gallon capacity,I am after some advice as a beginner.
The pond has a 20ft stream/waterfall into two joined ponds,the stream is concrete but has now been sealed,the ph is at present 9.
Is this suitable for fishkeeping,and if so what types would you recommend?
If the ph is still too high,what would be the best method to lower it.
Prior to sealing the stream,the ph was in excess of 10,so it has reduced (a bit)
Thank you
