I have removed the stock pump and replaced it with a MJ1200. The outlet is a locline Y with round nozzles. I still dont think I am getting as much flow as I would like.
I tried a Rio 6HF but it was a tad too big for the back chamber and caused some rattling noises.
I would like to get closer to 30x turnover in the cube so with the MJ1200 I need another 60 gph.
I was considering swapping the MJ1200 for a MJ900 (230gph) and adding another small pump, but here is the problem.
The heater sits in the first chamber (along with a block of filter foam and a bag of carbon), there is a refugium in the second chamber and the return pump is in the third chamber.
Where and how can I add more flow?
Here are my ideas:
1. Move heater to chamber #3. This would free up chamber #1 for another pump with a hole drilled in the false wall. The only problem with this is that the heater could be exposed to the air when the water level drops.
2. Add another small pump to chamber #1 along with the heater and drill a hole in the false wall. Problem is finding a pump small enough to fit back there along with the heater.
3. Moving heater to chamber #2 to make room in chamber #1 for another pump. Problem is having the heater in the same chamber as the refugium...not sure if thats such a good idea.
I think the best option would be to do with idea 2.
Place a MJ900 in the third chamber as the return pump pushing 230gph @ 8.5w. Place a MJ400 in the first chamber with the nozzle going through a hole in the false wall pushing 106gph @ 5w.
Total of 336gph spread out around the tank at 13.5w
I could even use a MJ600 in the first chamber and have a total of 390gph at only 16w. That would still be MORE flow and FEWER watts than the MJ1200 alone.
If heat issues arose in the summer I could simply shut off the first pump (MJ600) and save 7.5w
I could even add a wavemaker and have the two pumps alternate. How does that sound?
Any advice is appreciated.
Thanks!
