Ok I started with a koralia 1 a mj 1200 and a 400. I ordered a koralia 3 and a ecomod for the mj. The k 3 was a big step up from the 1. I havea 65 g tank if this helps. The one was about the same as the mj 1200 it was spread out better than the mj 1200.So I put in the k 3 and the k 1. Today I got my mod kit. OMG. I put it on the 1200 even they say it not rated for it now. The mj 1200 will cavitate some. It was a little noisey too. I put it on the mj 400 and it was perfect. It put out more than the koralia 3 Not a ton more but a noticable difference. It claims to be 10x more. which would put it about 1040gph, the k3 puts out a rated 850 gph and the k 1 around 390 i believe. The downside is that the ecomod didnt come with a mount for the mj pump. I am thinking of just aking it off my k1 and retro fitting it. I am still amazed at the output of the mj400 . this is day one I will have one on one side and the other on the other. Maybe i ll add some pic s tomorrow. Great mod for the $$$ paid 19.99. If you want to use your old mj pumps this is the way to go. Very happy with the mod.
