Too little iron can stunt plant growth, whereas too much results in algae problems, so it is important to keep levels in check. Iron is one of the main nutrients of aquatic plants and should be available in the water of freshwater aquariums. CO2 is especially important for healthy plant growth too, for photosynthesis to occur.
We have a variety of Iron and CO2 test kits available to monitor the levels and give accurate, fast results, from trusted manufacturers such as Fluval and JBL. Everything you need is included in the sets, some are even designed to permanently sit in the tank for constant readings. and refills are available to purchase separately.
