Maxi-Jet powerhead question

[spikehs]

Hello,

I have a maxijet 600 attached to my kalk reactor and it doesn't seem to mix the kalk all that well (I think the pump might be on the fritz despite my cleaning).. so I want to upgrade it to the maxijet 1200... however I was wondering if the intake/nozzel bit (the part the screws off) is a standard size? As it is glued into the kalk reactor and i don't want to take it off particularly... thanks!

Yes. Same size.

I'm not sure actually. I have the same situation on my kalk reactor, ie. a MJ600. The original crapped out and I wanted to replace it with a MJ12 because I had a couple spares of those. But I wasn't able to get the cap (that's attached to my reactor) to fit properly on the 12. I went and bought another 600 and it fit. Sooooo... hopefully it works for you, but ... it didn't for me :redface:

Does the 600 seem to have enough flow to mix the kalk properly? If it was a case of my 600 just been a bit weak, then maybe i'll just do the 600 again...

It seems to be working OK for me. My reactor is not terribly large, about 4" diameter and maybe 24" tall.
