Aquaponics disaster.... Help pls
Have finished the set up and just bought 50 comet goldfish. Introduced them into the tank and they looked happy, fed them and they were eating. Went out this morning and all fish dead! Totally gutted. Not just cos of the cost but that I killed the poor things.
The tank is about 900 litres and was filled fresh, our water is bore water and drinkable. I am thinking it may be the mineral content?
What shall I test for before buying more fish?
There is no chlorine in the water.
