I've about had it with running my Calcium Reactor feed through my manifold. I tried a mj1200 and I still dont get the constant flow I'm looking for. I really could use some advice on picking up a Peristalic pump off ebay. Please keep in mind I'm not looking to spend a fortune on one. I do have an Iv pump but its discontinued and Im missing a free flow protector clip which is really hard to find since they aren't making replacement parts any longer. Any suggestions?
Peristaltic pump question
- Thread starter bcavalli

The problem you will run into is that you need to be able to adjust the flow rate of the parasitical pump you get since valving it down does nothing on this kind of pump. That alone will push you into the high price range, or DIY with a stepper motor.
For which exact pump to get there is a thread on this on RC somewhere that goes into what model pumps work. They seem to really life masterflex pumps. Id expect to spend no less than $200 on this.
This is the exact reason I took my calc reactor down a few years ago and opted to just keep doing 2 part dosing. If I ever put it back up, Ill be getting a parasitical pump to run it. Same goes for my sulphur denitrator.

Thank you sir. I ran into that thread. It's just mind boggling the number of options. Lol
I ran across this a while back when I was looking up the instructions for the iv pump you have.

Kind of an old blog post but it may be of some help. I'd be willing to look at it for you to see if it can be stripped down to work for your application.

Hey Brett... I have a couple of MasterFlex pumps I don't intend to use. I used one to feed a calcium reactor and it does have an adjustable flow rate. I'll dig it out and find the model number later tonight. Do your research and let me know if this is the direction you want to go. Price will be reasonable.
Crazy idea, but I had the MasterFlex in the garage pulling water from, and pushing water to, the calcium reactor in my office. About 60' each way. Worked well but I am changing direction and have the reactor off line.

That would be awesome Larry. I would very much appreciate it.
Hell, I'm interested in the other one! Been looking for something to do a auto water change.

Yup, but its not all important. Most of it is just so people can snag one on ebay and know what the flow rates will be with whatever tubing they have. You never know whats for sale and when so its letting you know there are lots of them that will work they are just slightly different.
Basically search on ebay and cross reference the model numbers with the thread, or vise versa, to see if its one that will work. Then do the same for the head and tubing and get the flow rates to tune it for your setup.
could be usable for a DIY stepper motor pump.
here is another thread you may be interested in.

Reef keeping, the only hobby that turns you into an engineer the longer your in it.
Thank you Sir, I really appreciate the info. Great DYI thread.

Following along on this thread.. I am going to be setting up a calcium reactor as well soon and looking for options..
Brett keep us posted on what works for you.

Absolutely!
My pumps are no longer available. But as a PSA, here are the ones I used. With all Masterflex pumps (and I believe most peristaltic pumps) the flow rate is determined by the RPMs of the pump motor and the diameter of the tubing used. Also, keep in mind the pumps are not quiet and produce a good amount of pressure. If used to feed a calcium reactor it's recommended to pull the water from the reactor. Pushing into the reactor could cause pressure to build and push water around the lid seal.
1) Masterflex 7543-20 with dual Easy Load 7518-10 heads. Single speed. I used this for auto water changes.

2) Masterflex 7520-?? With 7035-20 head. Adjustable 6-600 rpm. Reversible. I used this one to feed a calcium reactor.
Couldn't find a manual on this pump head.
Flow depends on RPM and tubing size. These pumps have either L/S 13 or L/14 tubing (I think L/S 13). I wanted to keep low flow to minimize risk.

Great information on their use Larry. I really appreciate it.
Thank you so much Larry! It was great seeing you again! I picked up a peristaltic pump and as soon as I get it up and running I'll post the progress of using one versus running off a manifold.
