My second MP10 arrived today. I was excited and stuck it in my tank without balancing the flow, but so far I'm very happy. They are both on full flow, but bear in mind my 60 tank is only 24 inches square. For a longer tank, I think I'd recommend adding a mp60.Helen, let me know how that second MP10 does for you on your tank. I havent upgraded yet, but I look to in the next month or so.
to add another option I would recommend to look into Tunze pump and new WP40(25) pump models. MP40 is a great pump but it's noisy. On the other hand Tunze and WP40 are pretty quiet. Another plus you can get WP40 for less then 100$ including controller which is a bargain.I'm wanting to upgrade my 37T tank to a 75 gallon. I would be upgrading tank, stand and sump. I was wondering if I needed to upgrade to the mp40 or could I simply just get another mp10?
