Lol drunkreefer (yeah I saw it at Seahorse and I saw it had nothing special beside the electrical and motor outside the tank), I believe this is a new one because the magnet protected by the outside cover and I dont thinnk any water can get into it, and around it have an orange o-ring on it. I know the older model you where talking about because I have two of them in my garage. Well it wasn't vortech it was for something else at my gf's but the concept is vortech :-)
