billpa Posted June 28, 2004 Share Posted June 28, 2004 one more question The kangaroo pump...how much can it pump volume-wise before you have to reset it? I have heard around 2 gallons. And what is required to reset it? just push a button? or do you have to reset the flow rate also? thanks F2B billpa Link to comment
fade2black Posted June 28, 2004 Author Share Posted June 28, 2004 I can pump indefinitely. I have never had to reset mine. I set it to match my evaporation rate and it just goes. I believe if you set the amount to be dosed to either 0000 or 9999 it will just keep going. The Kangaroo is an awesome pump. I turned off the drip alarm (which was very easy) and the thing just keeps going. Link to comment

Sounds like a good pump. bill Link to comment
fade2black Posted June 28, 2004 Author Share Posted June 28, 2004 Yeah, it has two settings. One for how much to dose in ml/hr and the other is for total amount dosed. For example, you can set it to 150ml/hr and then the total amount to 450ml and it will dose for 3 hours and stop. If you set the total amount to dose to either 0000 or 9999 it will run continuously. When I get home I will check for you, but I beleive it is 9999. I run mine 24/7 and have never had to reset it. Link to comment
billpa Posted June 28, 2004 Share Posted June 28, 2004 oh okay...I get it now...thanks F2B! billpa Link to comment
fade2black Posted June 28, 2004 Author Share Posted June 28, 2004 No problem. I'm happy to answer any questions Link to comment
billpa Posted June 28, 2004 Share Posted June 28, 2004 what kind of timer do you use that will allow you to do such frequent intervals? I need something like that for another project. billpa Link to comment
billpa Posted June 28, 2004 Share Posted June 28, 2004 was also curious how thick are the walls of your chamber (the tube)? thanks. billpa Link to comment
fade2black Posted June 28, 2004 Author Share Posted June 28, 2004 I use a digital timer you can get at any HD or Lowe's. They are about $20. I use 1/8" wall tubing. These aren't high pressure so going with 1/4" is overkill and adds too much to the price IMO. Link to comment
MrKrispy Posted June 29, 2004 Share Posted June 29, 2004 okay, one last question: what type of tubing? I wasn't sure if my silicone tubing would stand up to the high pH of kalk for any length of time. Link to comment
fade2black Posted June 29, 2004 Author Share Posted June 29, 2004 I use the type of tubing that comes with RO/DI systems. It's a thick semi-ridgid tubing. CO2 tubing would probably work too I guess. Not too sure on that though. Link to comment
fade2black Posted July 2, 2004 Author Share Posted July 2, 2004 Originally posted by billpa do you think the kangaroo could handle pumping RODI into the reaction chamber and then from the reaction chamber straight up around 3-4 feet? biillpa Sorry it took a while to answer this for you, but mine had no problem doing this.

billpa Posted July 3, 2004 Share Posted July 3, 2004 cool...thanks for the info F2B...I actually picked up a flexiflo pump off of ebay...same stats as the kangaroo 324...was going to get the kangaroo but the cheapest I found was a hundred bux...I got the flexiflo for 60 shipped...will let you know how it works out...btw...great thread you started! billpa Link to comment
fade2black Posted July 6, 2004 Author Share Posted July 6, 2004 Yeah, $100 is about the going rate these days for a Kangaroo. I think I paid $90 for mine about 9 months ago. Link to comment
blindreef Posted June 5, 2005 Share Posted June 5, 2005 This is a really cool project! I really think Im gonna try it. Everything else I've seen requires much more maintenance to keep running than this thing would. What kind of stirrer is that? I looked at a few on ebay and they seem to run between $30-500. What do I need to run this reactor? Link to comment
fidojoe Posted June 5, 2005 Share Posted June 5, 2005 I run my kalk reactor (a stoney reef) off a basic dosing pump with a float switch. If you look around, you can find one for about $90. I have tested my pump, and it will pump water up over 15 ft high. I just use regular 1/4" OD vinyl tubing to feed in and out of the reactor. What I like about the float setup is that I don't have to do any math to figure out what to top off, its totally automatic, escpecially since the evap rate in my tank fluctuates. I've used this setup over a year now, and I love it. BTW, check www.ah-supply.com , I think they still have the dosing pump I'm talking about. Link to comment
fade2black Posted June 7, 2005 Author Share Posted June 7, 2005 blindreef - The stirrer is made by Hanna Instruments. I use a kangaroo medical dosing pump. You can get them off eBay for about $90. I then just closely match my evaporation rate and that's all there is to it. I cleanout the reactor about every 6 months or so and it has been running for close to 2 years now. Link to comment
