I started to raise the salinity following early signs of Ich in goldfish, aiming for 0.3%. After adding 48oz of API salt to the 1800 litre pond I thought it best to test rather than overdose the pond so I bought a conductivity test meter and Ph Meter.
The issues I have are
a. I'm not entirely sure how to convert the UD reading to percentage (sounds simple but the info on the web is confusing)
b. My Pond UD is approx. 4600 which I believe should be around 0.3% but my tap water is over 7000! and is not salty. The pond was originally filled with this tap water treated with a water safe treatment. The water in the area is hard and therefore will have dissolved solids, probably carbon, magnesium and potassium ions. Does this mean that my meter is useless for testing the salinity? Is there any other way I can accurately test salinity.
Water temp daily range is 19C to 24C and Ph 7.8 to 8.4.
Good news is that the goldfish that had white patches appearing on it's sides has shown really good recovery, to the detriment of my browning Marsh Marigold. Sadly I think I accidentally suffocated the other Goldie that appeared to have Ich whilst quarantining. Other fish and frogs all look happy.
