RO Units

RO units are a great way to ensure your tank has healthy water that is free from nitrate, chlorine, heavy metals, and other potential contaminants. Without one of these units you’ll see some serious algae build up in your tank. What happens then? Sadly, you’ll have to spend a pretty hefty amount on additives and treatment…and we certainly don’t want that.

Luckily for you, using a RO unit to filter water can prevent this, because the water is filtered to the purest possible form. Pure water means healthy and safe water. And what’s more, these units, like the Brita compatible replacement filters, can also be used to purify tap water for drinking applications and everyday usage. Because no one wants to consume water that’s full of nasties now, do they?

Whether you’re looking for a small residential RO unit or our larger commercial 200gpd or 400gpd Reverse Osmosis Unit, we have you covered to get you on the way to perfect water purification. With optional DI resin chambers and Booster Pumps, you’ll be spoilt for choice. benefits and long-term value RO units bring easily outweigh the initial cost.
