Grotech is releasing their Reef Stream pumps again, they were on a short break from production but apparently Grotech has taken it upon themselves to get these back on the market. You might remember other Reef Stream pumps for general use, but these new Reef stream pumps, the first being the RS-5000 or RS series, are designed to be placed inside your aquarium. Like the name suggests the RS-5000 Reef Stream pump pushes 5000 lph (1320 GPH) of water while consuming a low 12 watt of the zappy stuff. The magnetic mount is great for glass up to 15mm (0.59″) thick or you can use the included suction cups if you really want to make your life harder. Expect these to stay in the EU and perhaps the UK.
