dhoch August 28, 2006 Share August 28, 2006 The kangaroos are good pumps the only drawback is that they are NOT controllable... it has to be always on... That's why I don't use em. The pumps from innovative aquatics are basically the same thing, but modded (if I knew how I would do it myself) so they can be "controlled" Dave Link to comment Share on other sites More sharing options...
tygger August 28, 2006 Author Share August 28, 2006 Dave, if I don't get the Controller Interface (a/c adapter), how does the Nautilis pump normally get it's power? It sounds like if I get the CI, I'll have 2 power cords for the 1 pump. Is that right? Link to comment Share on other sites More sharing options...
dhoch August 28, 2006 Share August 28, 2006 The nautilis will come with it's own plug. The CI adds a 2nd plug that would be required to "control" it. Here is a pic of the back of mine: Dave Link to comment Share on other sites More sharing options...
tygger August 28, 2006 Author Share August 28, 2006 Dave, you explained it better than the Innovative! lol. I haven't heard back from Innovative yet on this, but do you know if this pump come with all the tubing I need? It doesn't say how much length is provided. And is the regular 300mL size good or should I request the smaller 85mL/hr size? Link to comment Share on other sites More sharing options...
dhoch August 28, 2006 Share August 28, 2006 I'm pretty sure I have the bigger (300ml) size... You might need some additional tubing depending on how far your run is, but I doubt it... it should come with all you need. Dave Link to comment Share on other sites More sharing options...
Eve August 28, 2006 Share August 28, 2006 I have the nautlis 2... 2 component is like 2 part additions (C-blance, and other make stuff like this) one part adds alkalinity the other part calcium and you want to add them balanced in small amounts. Dave - what type of containers are you keeping your Alk & CA solutions in (Aquadosers/home made plastic container, etc.) that you are using with the Nautilis II?

dhoch August 28, 2006 Share August 28, 2006 I'm not doing 2 part dosing anymore... At the time I was I was mixing RO/DI water with homemade alk component (baking soda & RO/DI) and homemade calcium component (turbo calcium & RO/DI)... I was just using a couple of small buckets Dave Link to comment Share on other sites More sharing options...
Eve August 28, 2006 Share August 28, 2006 I'm not doing 2 part dosing anymore... Dave Moved to the dark, scary side - the calcium reactor :-) Link to comment Share on other sites More sharing options...
dhoch August 28, 2006 Share August 28, 2006 Yup... I think it's so much easier Dave Link to comment Share on other sites More sharing options...
tygger August 28, 2006 Author Share August 28, 2006 Dave, so what are you using the nautilis pump for? Your calcium reactor? Link to comment Share on other sites More sharing options...
dhoch August 28, 2006 Share August 28, 2006 No currently is for my kalk reactor... I do want a 2nd one for my calcium reactor though... Dave Link to comment Share on other sites More sharing options...
tygger August 29, 2006 Author Share August 29, 2006 Going a bit off topic.... So should I dose at night only or 24/7??? I got the 300mL hosing. If I dose 24/7, would I still dose at approx. 158mL/hr? Thanks for the info!!!!!!!!!! THe pump should be arriving tomorrow. Link to comment Share on other sites More sharing options...
dhoch August 30, 2006 Share August 30, 2006 I dose only at night.... If I did it during the day it would drive the pH in the tank too high is my guess... Hard to say exactly how much you will be dosing because there are many factors... The best thing to do is to perform a little test when you get the pump.

tygger August 30, 2006 Author Share August 30, 2006 Ok, my pump just came in... the tubing is longer on one side. Does it matter if the longer side is the input or output??? Link to comment Share on other sites More sharing options...
dhoch August 30, 2006 Share August 30, 2006 No...just use it however is better for you (for me a shorter draw and longer out worked better. Dave Link to comment Share on other sites More sharing options...
tygger August 30, 2006 Author Share August 30, 2006 Yup, that'll work best for me also. Thanks again! Link to comment Share on other sites More sharing options...
jason the filter freak August 30, 2006 Share August 30, 2006 couldn't you just cut it:? Link to comment Share on other sites More sharing options...
tygger August 31, 2006 Author Share August 31, 2006 I could cut it, but I'll prob. leave it in case I need to move the pump to different locations. Link to comment Share on other sites More sharing options...
tygger August 31, 2006 Author Share August 31, 2006 The tubing that came with my High Volume set is 85ml/hr. If I set the pump to 100ml/hr, does the diameter of the tubing really matter? I would think that the only thing that matters is the tubing wrapped around the rollers. What should I do to keep the tubing a couple inches from the bottom in the kalk reservoir? Its very flimsy and if I just dropped it in the reserv., it curls up. Link to comment Share on other sites More sharing options...
Guest fishwish August 31, 2006 Share August 31, 2006 When this one dies, I'll probably buy a kangaroo 324. I've seen reconditioned units pretty cheap several times. tim Check eBay for reconditioned ones...$50 -$150. (Guess you can tell I shop on eBay a lot! ) Link to comment Share on other sites More sharing options...
dhoch August 31, 2006 Share August 31, 2006 Yes the diameter of the tubing does matter, a bigger diameter tubing will be able to pull more water... trust me... As for how to keep it out of the slurry on the bottom...I took a small piece of pvc pipe and lightly rubberbanded the intake tube to it...

tygger August 31, 2006 Author Share August 31, 2006 Thx fishwish. But I just bought the Nautilis one for $170. Dave, It's still not making sense to me... The way I understand it is that the size of the input and output tubing is independent of the amount of volume dosed. The only thing that should matter is the flex tubing that is wrapped around the rollers which provides a constant volume regardless of the input/output tubing.

dhoch August 31, 2006 Share August 31, 2006 There is a limit to what I sadi (i.e. an 1" tubing is not going to work), but the fact that the tubing is fexible will mean that it can expand to hold greater volumes if it is sent it's way.

tygger September 5, 2006 Author Share September 5, 2006 Dave, I've been using this for a few days now and have been meaning to ask... when set a specific dosing rate, is it normal for peristaltic pumps to dose at the same "speed" (number of drops/sec) no matter what the dosage rate is set at? It looks like these pumps dose at one rate and is controlled by pausing the rotor for a specific amount of time depending on the set dosage rate. Secondly, I don't remember hearing your make ANY noise. I can hear mine whine as the rotor turns... Link to comment Share on other sites More sharing options...
dhoch September 5, 2006 Share September 5, 2006 Chak, Yes the rotor turns at a fixed rate, and the dosing rate is controlled by "pausing" it... thats the way they work... much more efficient for determing dosing rates (which is why they are used in the medical community) as compared to a variable speed rotor. Mine makes a slight noise, and if you know what you are listening for you can hear it, but typically people hear the fans not the dosing pump.
