Treatments is a blanket term we use for various different water additives, not just for the nasty things in life like when your fish are ill but also for enhancing water quality. For example a water de-chlorinator takes harmful chlorine out of the water, chlorine kills beneficial filtration bacteria, it also harms fish’s gills. If keeping specialist fish like Discus you may want to alter the PH value, this is yet another water treatment. Treatment to help your plants stay lush and green, the list is almost endless! Then of course the serious business of treating poorly fish is also taken care of in our full range.
