hotrodded CPR bakpak

[edgerat]

So, I was sooooooooooooo inspired by Mike's skimmer that I decided to hot-rod my little cpr bakpak on the 30gal tank. so it goes from this,

to this,

here's my little helper,

oh he's good,

so now tomorrow I am going to dremel out a little slot in the bottom of the cup so that I can slide the cup down into the skimmer and collect the foam

I have been using this upgrade for so many years... Its veryeffective specially if youuse wooden diffuser on a 2 outlet air pump.

Usually the setting is the cup is at least 1/4" below the water line...

With these configuration... it will need to be lifted at least 1/2" above the water line.

have fun...

Have you done th e Maxijet mod yet or are you still running the rio PH on it? I did the MJ upgrade it is head and shoulders better than the air stone without having to plug in another item.

Maxijet Mod???? A friend is setting up a tank, with a backpak... and I've never liked the way the Rio's work on those. Is there a link to this Mod???

Not really a mod. Replace the pump with a MJ. Buy a inlet venturi kit from premium aquatics for $8, thats it.

Easy enough. Thanks Don, I'll pass that on to him.

this one actually came with an MJ1200 already on it. On my 72 I had to replace the RIO with a MJ1200 that I got for FREE from Petsmart out of a dead SeaClone package WOOHOO hehe

IME, the Maxijets is too powerful for the backpac dimensions to handle. A lot of bubbles are coming back to the tank.... I still prefer the rio and airpump combi...

 

[reedman]

No problem on mine Cesar. Not sure what caused the extra bubbles on yours, but this worked night and day better than the rio or the rio + air stone. Maybe I just needed a really big airpump, but I had a dual output on it and it still didn't perform like the MJ setup. My experience

 

[edgerat]

I am running the MJ and the airstone and I have no bubbles coming back to the display. Just for giggles I messed with cutting the air to the MJ and just let the stone do the work but this created a TON of microbubbles in the display so I turned the air back up and VOILA! micro bubbles gone!

 

[snobanker]

Are the dimensions for the MJ1200 and the Rio600 close to the same? I was thinking of trying this mod but I have the pre-skimmer overflow box on my Bacpac and I want to be able to use it. Will the MJ fit in it? Anyone with a skimmer box using the MJ1200?

i use the mesh modded mj1200 and its quite the beast

 

[ashton]

i also used a mesh modded maxi jet 1200 when i was using my bak pak and i never had any issues with microbubbles in the display.
