I have a problem with my pond.
When I put my hands in the water if I have a scratch or small cut on my hand it stings as soon as I have contact with the water, stops stinging as soon as my hand is dry
I am not being bitten by anything and water looks good and clear.
it doesn't seem to be bothering 2 yabbies, rosy barbs (fish orphans that have been breeding in there for 2 years) or a couple of frogs and water lilies are growing well.
this doesn't happen with contact with any other water but has been constant with my pond water for about 4 weeks.
anyone have any ideas?
thanks in advance
