Will a MJ1200 fit in chamber 3 of my BC14?

[vresor]

I already upgraded from the stock pump to a MJ900, but the flow is still anemic. It doesn't help that I've added a second LocLine nozzle to divert return flow at my Monti cap. Squeezing the 900 down in the stock pump chamber was tight; will a 1200 fit? Thanks.

[Fsurocks99]

I can but it will be tight.

[vresor]

Thanks FSU. What pump do you have in your BC14?

[Fsurocks99]

I have the 900, but before I upgraded I certainly considered the 1200.

[nanojg]

how are your temps running with the 900? In my 24 gallon nano the temp went 3-4 degrees hotter when switching from the 900 to the 1200. In a 14 gallon tank I would expect the temp to rise even more.

[Fsurocks99]

I dont see much rise in temp but that is probably because I have an open top.

[nanojg]

the temp question was really for vresor, if he is considering switching to the 1200, then temperature should be a consideration.

[vresor]

My BC14 runs at 80 degrees. I didn't notice any increase in temperature when I went to the MJ900. I used to use a 20 watt halogen bulb behind my fuge and that would push the temperature up to 82 by morning, but since I changed to a 13 watt cool white CF it's back at 80. The tank sits on a kitchen counter where it is almost always 72-75 degrees.

[nanojg]

I bet if you switch to the 1200 your temp will rise at least 2 degrees, probably more like 3-5.

[vresor]

I'm not too familiar with the 1200. Isn't it the same design as the 900? I can't trend my heater to know when it is running, but my guess is now and then even with the 900. Why would the 1200 contribute so much more heat?

[Mark426]

1200 and 900 are the same size.
MP900 120V/60Hz 8.5W 230gph (870lph) 46" 3.5" L x 2" W x 3.25" H
MP1200 120V/60Hz 20W 295gph (1110lph) 69" 3.5" L x 2" W x 3.25" H

[vresor]

Sounds like the 900 is significantly more efficient. It produces 900 gph consuming only 8.5 watts. The 1200 produces only 33% more flow but consumes 135% the wattage? ***?

[nanojg]

the 1200 is actually a lot more powerful, but it does produce more heat. Ive had both in my nanocube 24, the 1200 seemed like it was at least twice as powerful, but it raised the tank temp 3-4 degrees. Apparently the 1200 handles head pressure better than the 900 (about 1.5 feet in my nano).

[vresor]

Hmmm, in the trade-off between flow and heat (and the subsequent effects of evaporation and make-up demand), I'll choose to say with 900 gph of flow. Maybe I'll hold out for a Vortech MP10?

[InLimbo87]

Why not stick with the 900 and go with a Koralia nano/1 on the opposite side?

That's what I did with a Koralia 1.

[nanojg]

Not sure if you mistyped but the MJ900 is rated at 230 gph not 900 gph

[vresor]

Well, it wasn't so much mistyping as it was assuming. The 900 puts out 230 gph and the 1200 puts out 295 gph. Still, that's not in proportion to the watts they draw (and subsequently the heat they contribute to the tank). What's the difference?

Thats a good solution. You can also add a MJ606 in chamber #1. Thats what I did and noticed a very slight temp rise. There are threads here and on other nano reef sites on how to do it.
