Ordered new lights, return pump, and MP40’s, I have to say I’m very impressed with the improvement to the MP40’s and the lights! My gen 1’s have huge PS’s and the fan is exposed to the tank, the new design is so much quieter and doesn’t have the huge power supply! I really like the new MP40’s, the propeller is supported end to end now, the connection from the dry side to the controller seems beefier, the spacers are now like a hard rubber compared to the original ones. Updating the light with Mobius was easy. I wanted to mess with the pump and MP40’s but i now they have to be under water and my tank isn’t set up yet.
