Well I'm in a little bit of a bind. I am currently running an 46 gallon bow front mixed reef. I have only one mp10 nor wireless and I need more flow. My buddies has 2 Mp40 he will sell me for 175. My question is should I just get the 2 mp40s? Or should I just spend an extra 65 bucks on top of the 175 and get a new mp10 so I have two mp10? But then u wouldn't be able to have them communicate with each other because my original mp10 is not wireless. I could upgrade it to wireless for 100 bucks. But them I would have almost the same amount into both mp40s. Yes 2 mp40 would be more than enough maybe to much for my tank. Idk what do you guys think I should do?
