Only SA/CA Cichlids and I dose with excel as per the instructionswhat fish are in the tank?
do you add any chemicals/ fertilisers to the tank?
Be careful with Excel. Like most liquid CO2 products, the active ingredient is glutaraldehyde, a powerful disinfectant (It's also used to sterilise heat sensitive medical equipment and in embalming fluid, amongst other things). A tiny overdose can kill plants so goodness knows what damage it does to fish.I dose with excel as per the instructions
