I recently purchased a large lot of reef supplies from someone who was clearing out their basement and hadn’t kept a tank in 7-8 years. With this I got several old model vortech powerheads. The wet sides were all toast, so I was wondering if it is worth getting wet sides for them, and if the wet sides are even compatible. There are MP-40w, MP-40, MP-20, and MP-10 models. Any insight is appreciated, thanks!
