SpectraPure LiterMeter III experience?

[ReefLife1680]

elosusa ... good idea. I might just look for the masterflex on downtime and if i ever decide to run a reactor, i'll probably go with that one. The aqualifter did not work for me, that's why i'm going with the LMIII - not enough psi to push water through there ...

 

[jt_redmist]

Can the LMIII be used to feed a Ca reactor? The turning on 150 times a day got me a little confused, because if that's the case it wouldn't be a constant flow, right?

 

[ReefLife1680]

jt_redmist ... that is actually what everyone uses them for. From what I understand, you set the # liters you want the sytstem to get dosed and it will just take that # and divide by 150 and automatically turn itself on, dose the appropriate amount, turn off and repeat throughout the day ...

elosusa & Ereefic & javajaws ... chime in to confirm/correct my explanation? They currently run them on their tanks ...

I use mine for evap topoff only currently. I do know some people use dosing pumps for feeding a Ca reactor, but not sure how many use LiterMeters vs. something else though.

 

[ReefLife1680]

I know the LMIIIs put out 40+ psi ... as opposed to the mdeical dosing pumps (put out about 15 psi). If the medical dosing pump works for reactors ... i don't see why the LMIII wouldn't?

is that valid reasoning javajaws?

 

[jt_redmist]

Thanks for the quick reply guys. I'll be using it mainly for topoff, but would like to know that feature is there. I'm so close to putting in my order

 

[javajaws]

I don't think you'll have to worry about the LM pump not being able to handle the pressue of the reactor....shouldn't be an issue.

 

[ReefLife1680]

jt_redmist .. where are you buying it from? I'm looking to get one too ... just still on the fence about it (99% sure though)

 

[Ereefic]

You are correct, it doses 150 times per day.

I don't know how well they would work on a calcium reactor with the constant on/off. You want the pH inside the reactor to remain steady, and with nothing coming out of the reactor when the pump is off, yet co2 still going in, don't know how that would work.

I just 'T'd off of my return line, tapped in a JG fitting, and supply my CR that way, works great and easy enough to do.

I tried an aqualifter on a CR, but had less than stellar results.

I use my LM III for top off only. I wouldn't want to run it for a Ca reactor because I want water circulating through it constantly. Just checked the psi for outlet pressure and it says 20 psi on my medical pump. I can't imagine the LMIII is better at pressure than the medical pump. The reason why these types of pumps can handle so much pressure is because they are not "pumping" water like a standard water pump. They are simply using a wheel with rollers on it that pinches the tubing as it rolls. The advantage is they don't get clogged since they are not in contact with liquid and they prevent siphoning because the tubing is always being pinched. Hope that helps.

How much PSI DOES an aqualifter offer

I'm not concerned that it can't handle the pressure. My concern is that it needs to supply the reactor with a constant flow, so the Co2 does not build up

I haven't looked around that much, but right now Premiumaquatics has them in stock and seems to be the lowest so far.

 

[Ereefic]

I don't think the aqualifter has much PSI, since it isn't able to draw very far at all.

In regards to the pressure of the LMIII, this is from there website.

"The pump's planetary direct drive is at an 11:1 ratio, thus providing enough torque to generate over 40 pounds of pressure. This incredible lift enables the LiterMeter IIIâ„¢ to pump over 60 feet above itself at a flow rate of over 250 ml/min. It can also draw up from 25 feet below."

are you setting up a Ca reactor for the first time, jt?

No, my Ca reactor is already up and running. The reason I'm looking into feeding the reactor with the LMIII is due to some erratic effluent flow coming out. I don't think this is the reactors fault, but rather the way I'm feeding it. But that's a different topic. I'm hoping by using the LMIII to feed the reactor I would get a more consistent effluent flow.

 

[ReefLife1680]

I never really though about the CO1 problem ... i guess everything on the LMIII looks good except the CO2 buildup then ...

 

[elosusa]

I'm thinking it could be done but it would be a lot of "tweaking" to get it right. I think you would have to have your co2 on a solenoid and controller and it would be a pain. Did you see the stuff about the medical pump earlier in this thread? This is the best way.

 

[Ereefic]

Return line ---> 'T' ---> JG fitting ---> JG Valve ---> RO tubing line to the reactor

This works awesome and will cost you around $10. The only problem I had with this set-up was media clogging my output from the reactor to the sump. Otherwise, kept good drip rate.

 

[ReefLife1680]

elosusa ... i think medical dosing pumps are expensive and faily unreliable. IMHO that's why i'm going with the LMIII but for a calcium reactor what is the equivalent to a LMIII ... masterflex ?
