As for heads for the water change, I would suggest 7518-10. It has stainless rotors and adjustable occlusions. You could go non stainless with a head such as the 7518-60 which also has a stainless head but is made of different plastic. There is also the 7518-00 but I'd go with the 7518-10 if it were me. All those models support a wide range of tubing including LS17. LS17 is the most common and most practical since you can get it from US Plastics via the links in the first page of this thread.

I've posted a design somewhere along the way that could remedy this. Instead of shutting down the AWC by stopping flow on the pump you could put Tees in a high point in both suction lines prior to the pump head that are attached to solenoid valves. When closed they would allow the pump to create a vacuum and operate normally. When open they would inject air into the system and a vacuum wouldn't occur. This does add a failure point but as long as you have a conductivity probe I think the risk is minimal. In the end, I would like to think of this solution as a temporary one while you are waiting on another good deal for another continuous drive. The 3rd head would be transferable to the new pump. Something else to consider. If you don't want continuous you could always go with a more simple economy drive to do the AWC and just plug it straight into your apex and run it 6 hours a day or there about. They aren't as quiet or adjustable flow. You purchase them with a set RPM. I use them for my ATO pumps, they last a very long time but really shouldn't be used in continuous duty. They are often available on the secondary market at a low cost. https://www.coleparmer.com/p/masterf...ed-drives/4509

Also, why would I not want to just do a continuous water change (that ran 24/7)? Quote:
Thank you again for your reply and recommendations! My new setup is going to be bullet proof, and this pump(s) will have a huge impact.

The flow rate varies with pump tube diameter. Adjustable occlusion just means you can match the heads pinch on the tube. If one head pinches less than the other back pressure may cause it not to flow the exact same amount. In the end, I don't think it's absolutely necessary. You'll want to balance the head pressure by tube lengths. Since I had an uneven run I had 25ft of tube coiled up on one side to make the runs even length. Worked great. The pumps push water better than pull so if your pump isn't exactly in the middle you will need to toy with tubing length a bit. Using larger diameter (3/8 vs 1/4) poly tubing to the pump makes a big difference here. Hope that makes sense.

Personally I would keep all 3 functions separate. At least that is what I do. I use one Masterfflex for ATO and one for Calcium reactor. (90 ml/min) I use the Apex Dos pumps for the AWC

Official: Masterflex Calcium Reactor Setup Thread
Thank god for Apex and there Advanced Leak Detectors. Just had a regretful email notification to tell me I had a leak in the Calcium Station (where the CA reactor and CP reside), everything did what it was supposed to and turned off, checked and was expecting a leak on the CA reactor only to find the silicon tubing (the bit that’s being rolled) had split, ran this setup for a few years now and never had tubing split like this, and it was only 2 months old.
Anyway: 1. Did I just get unlucky or is there an issue with the pump head? 2. When the pump heads get old do they damage the tubing more? Time for a replacement head? 3 Am I supposed to lubricator the rollers? Sent from my iPhone using Tapatalk |

Using the Tygon LS17 pharmed tubing, what is recommended in the first post.
I left the unit off, so will check them this weekend more closely. May just spend some money and buy a new pump head Sent from my iPhone using Tapatalk |

Check the reactor for clogs, it can split like that if the system is building too much pressure.
You can use penetrating grease (not wd40 but an actual penetrating grease) to lube the rollers. Cole-Parmer doesn't actually recommend lube though. Check for bearing wear. It was likely a fluke.

I’m currently using a 7518-00 pump head, the newer model is 7516-00, if the 7518 works with my pump, will the 7516 work also?

It is not a question of working with the pump, it is a question of working with the LS-17 tubing. Both pumps will work wit the tubing.

Is there any way to identify a pump head with a stainless rotor head?

I recently switched from a Reef Octopus reactor to an Aquamax3. I use a Cole Parmer 7523-80 with a 7518-00 head and an Aquarium Plants regulator. My flow rate is 90ml/min. What is the drawback to colled rolled steel rollers?
With the Reef Octopus the reactor ph held very steady but with the Aquamax the ph continuous swings. Not much but a variance of .03-.04 (see attached graph). The other change was from using ARM media to now a combination of Arm and Newborn. I know the variance is small but I think it is making more difficult to maintain my tank dKH.

Just built a little better and survives in our environment better. I wouldn't go out and buy a SS version if I already had a CRS version. Just if you're shopping for a new head...

I’ve got a GEO 8x18 that has the JG fittings and it’s currently just circulating saltwater through it without CO2. For the extremely unhandy folks, can you point me to a diagram of how to hook up the masterflex pump? Any recommendations for the masterflex pump these days? Thanks

*Also, in the user manual, it says I can control it with RS232 / Serial, so easily could be controlled with an Arduino for home users. Full control could then be granted, giving you access to see the motor speed/direction, change speed/direction, start/stop, prime. But for most of our usage needs, I think adding the 0-10V from the apex to throttle up/down will be enough. APEX could only send 0-10V for speed. You can set in device to make 0V = 0ml/minute and 10V to = X ml/min, so you can choose max flow to be 100ml/min for instance, if you wanted to limit max speed via remote control.

The manual says STOP/START , DIRECTONCW/CCW, PRIM via contact closure... so I THINK that means if you short the +/- terminal for START/STOP, then the motor will START in shorted, and STOP if opened... same for prime, same for direction... that can be done with a paperclip or solder on the back of your connector... Someone let me know, this is easy to test. Put 10V on the 10V pins, then short the start/stop pins and it should go. You need to download the manual and read how to get into remote control mode.

Setting the max ml/min in the controller is smart.
