While most of you already have some sort of PH monitoring device, most likely a PH probe inline with a controller, this new Reef Fanatic PH pen could be a great addition to your arsenal of saltwater products. Off the bat we could see this being great for a quarantine tank or for mixing up saltwater that you want to make sure you’ll have the right PH. What’s more is that this PH pen is below $50 at most online retailers. What’s not to like about that? Specifications after the break.
