Parasites form fast in aquariums. Even if you've been very careful with filtering, cleaning and medicating the water, every now and then, parasites would make an appearance in your tanks. With even just a small hint of ammonia, parasitic algae may form and hang on to fish. When an ounce of prevention isn't enough, you need a pound of cure in the form of Seachem ParaGuard, which is a product that controls and inhibits parasite growth once it starts.
Other medications contain formalin which is highly toxic when used improperly and when it is present in the wrong dosage. However, Seachem ParaGuard from Pet Store
doesn't have formaldehyde. It also doesn't have methanol. It doesn't contain any harmful chemical that can disrupt the pH levels in your tanks.
