Wow this is an old thread. MD3 is a Mag-Drive 3 pump.

Riiz Minsc, is that a gas seperator after the needle-valve on a pressurized setup?

krtismo Thanks for the update.

I'm going to try running the C02 through the Filter for a week or so, I have it hooked up that way now.

If i'm not happy then I'll be getting the Mag 3

Minsc Ok, verdict is in: This setup gets the

The only problem I encountered setting it up (well, the only non-personal stupidity problem) was a slow leak from the main O-ring. Reseating the seal and a bit of plumbers grease took care of that easily.

The pump itself is really nice. It is big, heavy and quiet. The loudest thing about it is the slurping and clicking sounds from the CO2 injection. I'm running the stock impeller (no needlewheel or mesh) and the bubble size is actually really good. With the amount of gas we are injecting (I use 2-3 bps), I don't think fractioning impellers are actually necessary, though they might be a bit quieter.

Jeff5614 Between the NW and the outflow. Here's a pic of mine before I installed it. The valve is on the output side and goes directly to the outflow. Excuse all the hose clamps. I had to use a couple of reducers to get it from a 1 inch fitting down to the 5/8 inch size of my canister tubing.

krtismo Where would I put the ball valve?

Here will be the flow order:

Intake--->XP3--->Inline heater--->C02 Injector--->NW Pump--->Outflow

Jeff5614 I went for the Mag 3. You can put a ball valve in to slow down the Mag if it's too much for your canister to keep up with.

Help me decide on a pump for needlewheel C02 diffusion

I'm trying to decide on a needlewheel pump to run inline with my XP3 and Inline Heater. I've narrowed it down to 3 options:

1. -Danner Mag 2 ($51) +Shipping
-This pump should work well with an XP3

2. -Danner Mag 3 ($57) +Shipping
-This pump is only $6 more, but might be too powerful for an XP3

3. -Don't buy a needlewheel pump, save some money, and just inject the C02 inline before the filter, and let the filter be the reactor.

This tank will be mostly ferns, mosses, and carpet plants. So I don't think circulation will be as important on this tank as it is with some of the bushier stem filled tanks.

Here is the DIY inline heater assy. (NOTE: fittings are temporarily installed on both units)


Here is what I will use to inject the C02 inline either before the NW pump if I get one, or before the filter intake if I don't get a NW pump.
