automatic water change

Ok interested in feedback so we need to get it up and running cause thats on my to do list with my new build and i am getting very close to that point.
 
For those of you running a Stenner, what number of tubes are you running in it?

I bought a "new" 170DM5 from ebay a couple months ago and have had a heck of a time getting it close. I get anywhere from a 6-10% difference in the intake and output.

I don't think it was actually new when I received it. As it didn't quite have that new shine to it. I suspected the tubes may have been streched unevenly, so I tried to remove them last night to compare and ended up tearing one. So it's new tube for me anyways.

I'm thinking about going with the #4 instead of the #5 as I'm betting that it will have a smaller tolerance for differences.

Thanks!

EDIT: Looking through the thread AquamanE and DRThompson are using #4's. Anyone else?

Why wait ......ask away I have had one up and running for years and have posted many times on this subject
 
I was also under the impression the dual head spectrapure unit was new. People have use two pumps for AWC previously but the one referred to here I believe is two heads on one motor right?

Received the LM3 a few days ago. I dont know if its a new "model". Its the LiterMeter III G6 with an additional pump, and an overflow safety system. .

I spoke to Jeremy on Thursday. I had a few questions he was very helpful, and i now know what to do.

I should have it set up by end of weekend. I will run it for a few months, and keep you guys updated along the way. I will document with pictures as I set it up.
 
As many of you know Spectrapure was kind enough to send FMAS a LiterMeter III- G6 for evaluation as part of sharing with all on this thread the different options available.

I will test this item for a few months and share with you my opinions on the product. I am currently running a Stenner pump for my AWC's. I have been using the pump for 8 months now.

Below are pictures of the LM3 with a Remote Pump, and Top Off Control Module as it arrived in my home.

This is a pic next to the Stenner:

And now just the LM3 and remote pump:

After setting it up I "calibrated" it as per the instructions:

More tomorrow as im being summoned for dinner right now :wildone:
 
Calibration and Set Up of LM3

First off the Calibration:

This was a topic discussed early in this thread as a disadvantage of the LM3. The following was my experience yesterday with it.

The calibration is very simple. It took me less than 8 minutes to perform it. I did however require an extra set of eyes since some of my lines are a good 10 feet away from the pump, so my fiancé helped. Basically you run the pump in calibration mode for each pump individually to reach 500 ml. What the pump does with this is figure out the flow rate and time it needs to reach the 500ml. I think this is an excellent feature. :thumbsup: what it does is take into consideration the length of tubing, and i guess head pressure into consideration. For me it made sense that one side needed to be pumped at 30ml faster rate since my new saltwater side tubing is ~25 feet since my SW is in the garage. For the old water dump i have ~ 8 feet of line. I will eventually try a side by side test but for now am taking the machines word for it. Since Stenner does not take this into consideration: Could this be why I have a difference between in and out??:mad:

The Set up it is also quite simple. You let the device know how much water you want to change out per day. In my case 2.5G/day, thats 9.46 L/day. What the device now does is divide that 9.46 liters into 150 times per day and does the work for you (mind you taking into consideration the RATE that came out of the calibration, so both pumps work at a different RATE).

I will closely monitor my SG for the next few days on a daily basis to make sure all is right.

More to come.........

Did you prime the lines (get all the air out) prior to doing the 500ml calibration? Even at that run the same head should be pushing nearly the same rate as a short run 30ml seems like a big difference. (that would be about 6%, though so not out of reason, the Masterflex L/S are only specified to be within 3% with some of the less common more expensive heads down to 0.5%) Possibly just the difference in the two motors/ pump heads, thus the need to calibrate each of them from time to time since they are not as accurate as say Masterflex? I think that is the issue with Stenner also, they have a pretty wide tolerance for flow rate from head to head as I recall, but there is really no way to calibrate short of restricting flow slightly.

Keep us Posted.
 
Since you can't control it with an APEX, dose it have its own system for making sure you don't run out of water on the supply side?

Yes the system is making sure that you have enough water for a given period of time. If you change 3 gallons a day, and you can only make water one time a week, then you want to make sure that you have 21+ gallons available.
