Low kH levels
Hi, I have a 60 litre tank currently with 7 tetras and 5 guppies, have a huge snail problem, which I'd like to rectify, however the snail treatment I have requires a kH of greater than 50ppm. At the moment my tank is only around 10-20ppm. What's the best way to get the hardness raised to around 80ppm? Do I need to do a full water change? Or can just do a 50% water change - adding some water conditioner? I've been using bottled water as our tap water is part bore water which has too much salinity and has been killing off fish from other aquariums in the area.
