I know several companies are working on some continuous duty peristaltic pumps. I do hope they have taken into account that we need ball bearings in the motors and not brass bushings like most stepper motors come with. Also, hopefully they were able to keep the noise down, steppers are notoriously noisy.
Edit, looks like they did. Seems relatively quiet!
After watching a bunch of vids, they are always running fast, I wonder what the lowest speed is. I assume it's low but there is a slight language barrier. Hopefully this is a workable solution! Maybe I can convince BigBlueTang to order one for his reactor so I can get some hands on with it
I sent BRS an e mail asking about it as well. They vary one product from the same company already. Maybe they'll buy one to test out and decide to carry them or not based on the findings. I'm tired of my loud masterflex but love the consistency. I don't want to drop 750 on a used pump to get brushless.

Nope, it's all the same. What effects the PH of your tank is the total amount of gas added to the tank. Either way, it's the same.
You can increase effectiveness and reduced ph output by adding a second media chamber.

Several companies have contacted me regarding this stuff. I know a few out there are working to solve the issue of a reliable continuous duty peristaltic that doesn't break the bank. To make the product with a decent profit margin it either is going to cost a fair amount or suffer in various places.
Hopefully we can get a reliable option soon. There are a LOT of people out there who I have helped source pumps and many on this thread deserve a lot of credit for helping others out! The setup is awesome, I'm proud of the effort the community has put forward to keep it going and help out their fellow reefers!

Your head should be designed for LS17 tubing. Not all are. There are some tabs on each side of the head where the tubing goes in and out that you adjust to pinch the tubing in place by sliding them down. They are referred to as occlusion.

If it is an easyload head use the tabs. If it is a standard load then I typically zip the two tubing sides together.
As slief pointed out the head must be designed for the right type of tubing.

I used to work 10 days out of state, 4 home, 10 away, 4 home for about 2 years. It was critical that I had stable and reliable equipment. Part of that drove this whole setup.
Exactly. I thought I could do the stream method but after about a week the stream would lessen. I travel at least a week a month, sometimes more, so this was necessary. It's not cheap, but considering how much we dump in to this hobby, what's another $400 to $1000.

How much did you pay for that pump? if you don't mind. Thanks

Was asked by the OP to re-post this from a separate thread:
I'm beyond sick of the constant fiddling around I have to do to keep my calcium reactor running stable, so I am hoping that changing to a peristaltic pump for the feed will be the magic bullet it seems to be for those who have tried them.
I'm looking for one that is relatively quiet... it doesn't need to be silent, as my fish room is already kind of noisy, but I don't want something that can be heard three rooms away.
I know new ones can be expensive, so used is OK if it is reliable.
Any suggestions in the $500 to $1,000 range?

Go on eBay and look for these brushless pumps...
7550-30
7523-60
7523-80
As far as heads go, zoom in and look at the photos of the pumphead to see if L/S 17 tubing can be used. If you’re not sure if a head uses L/S 17 tubing, look at ip model number of the head on the Cole Parmer website. In the specs, it will show what kind of tubing is compatible.

What are the best pump heads to find on ebay that are reasonably priced but are reliable?
Im still in the process of building my calcium reactor setup and have the masterflex 7523-70 pump with no pump head yet.
thanks
