Needle wheel pump recommendation

[30king]

Hi All,

After playing with a DIY needle wheel impeller mod (and that I need a new pump), I'm going to buy a needle wheel pump. I was looking at the RIO + and the needle wheel conversion kit from TAAMs website, but their e-mail is disabled and they don't return calls (out of business??). I am soliciting any info from you all on recommendations for other brands/ styles.

Also, what is your experience witht he "pinwheel" type versus others? I can buy strictly a pinwheel impeller for a Rio on e-bay, but wanted to get feedback first.

Thanks in advance,

TAAMs actually called me back. they don't distribute the conversion kit in the US anymore.

I am using an Eheim 1103 compact+ marine needle wheel pump. It has a variable output from 211 to 713 gph. I have it plumped inline with my Eheim 2028 canister filter, UV sterilizer and Hydor inline heater using Eheim's 16/22mm (5/8" ID) tubing. I have plenty of flow in my 40 breeder with this setup. The CO[sub]2[/sub] gets dispersed very well too.

Some people use the Danner Model Supreme Pumps w/ Fractionating Impeller with very good success. There are several different models to chose from.

Rio has the 600 and 800 RVT powerheads that work well too. These have to be submerged. http://www.marinedepot.com/powerheads_pumps_taam_rio-ap.html

I tried the 600 RVT one time, but I didn't like the extra piece of equipment in my aquarium. If I had a sump, it would be OK. But, it did break up the bubbles very nicely.
