I purchased the mp10 wireless for my tank from another reefer at R.A.P but I'm trying to raise money to visit a sick family member so I can't keep it. It's a EcoTech Marine VorTech MP10wES Propeller Pump w/ Wireless EcoSMART Driver. I also have a refractometer both the pump & Refractometer are used but work perfectly. I just need to raise some extra money. Mp10 wes $165 refractometer $20 I live in Sherman Oaks you can test them out B4 you buy.[/QUOTE]
