Yes please, I'll look as well. The L/S tubing with a precision head just seems the way to go.
The performance L/S tubing is $160/25' for non-ideal tubing... Madness!

Yup, that will work as L/S 17 tubing. We were discussing whether it's worth it to drop big bucks on L/S 24 if you already have a performance pump head, or to just buy a precision pump head. Verdict is, it's better to just buy a used precision head and use the tubing found in that original link

Update: Just bought a precision Easy-Load II head on Ebay for $100.
Now ill order that tubing and be in business shortly.
Here's a good question. What is the risk level of leaks on these? Are we talking people are cracking tubing and leaking left and right, or are we talking "if you replace your pharmed tubing 2-4x per year, your tubing should never fail and flood the place"?
I need to consider this since it will determine where (and how painful it is) to mount my masterflex.

I'm not saying it never happens but in 8 years the only two tubes (out of a bunch of these running) that I have ever had fail one of them I took a razor blade to simply to see what would happen and the other I didn't clean the head before putting it into operation. It had a bunch of gunk built up on the rollers. The 2nd one wasn't ls16 but was one size up and I have not had a failure since. I have 3 CaRx setups running masterflex pumps and 3 standard loads running my top offs.
I would not be concerned about a break but always recommend putting the pumps in some kind of shallow pan (not deep enough to flood the pump) with a leak detector to let you know if there was a leak.
The one I took a razor blade to didn't actually leak, it sucked in air

LS Precision tubing has a 1/16th inch wall thickness.
Theoretically you can safely run any tubing you want with that thickness. I believe you are right though. I had this all sorted out on my computer but lost the HD.

What are the best pump head model numbers to look for?

So I have a Cole Palmer 7524-00 Pump hooked up to my Ca Rx and am running 70ml p/min to feed my Heavily populated spa tank.. I am having to dose alk and mg daily to keep up with it and and i can't seem to fine tune my CP Masterflex pump in smaller ml steeps than 10.. I was at 50ml then went to 60 ml now at 70 but if I goto 80 its too much I think if I coulg go 75 it would be perfect, however My unit only allows me to adjust flow in 10ml increments ? I know they can function in 1ml increments as Ive seen it on youtube but for whatever reason mine is set on 10ml? It there a button combination or something to change the programming on this thing? I can't figure it out and I really need to fine tune my effluent. Can someone weigh in on this? I have tried to get the manual online but can't seem to get it for my exact model. Current pH is 6.55-6.58

Can you set it to rpm mode instead of tubing size? I've never used that specific pump.
Are you using a ph controller to control your reg?
You should keep the flow the same, just drop your ph a bit until it keeps up with the tank. If you hit 6.3 then bump the effluent flow.

Stainless easyloads are great. 7518-10 is readily available.

I don't know If I can set it to RPM ? I will have to check to see if theres a setting for "RPM" but it does have a tube size option, will post back on that one.. I do have a Apex controlling the PH in the system, Ive been told running it below 6.5 can turn everything to mud and potentially wipe my tank? for the 2 years its been running 6.5 has always been the off point but its almost always constant 6.57 - 6.58 pH.. I will drop my carbon dose by 1/2 second ? and set my controller to allow 6.3, I have had some insane coral growth lately as well as added quite a few new pieces and it just aint keeping up at the 70ml p/min but every so slightly I'm only adding about 25-30 ml of 2 part all p/day to offset and keep my doh at 8.25 .. however calcium is increasing out of sync ? I run zero mag in the reactor as well and having to dose 20-25ml p/day of esv mg supplement , so all and mg are slipping and ca is gaining. Ill let you know by morning what the results look like. Thanks for helping. :fish1:

There are multiple setting ive discovered on tube size like 20? Do you know which setting im looking for? Im running tube size 17 right now? Thats how it was set when i got it all i had to do was play with the effluent and ph. I dialed the co2 from 6 on my carbon doser to 5.25 and i also tuned back my effluent from 70 to 60 just to be safe as the lower ph may act quicker than me lol.. i will test again in the am to see what if any changes arise. Ive included some pics as it easier than trying to describe each 1, there are lots of options but heres a few that i grabbed.Thanks again

I'm so bummed!
I'd been keeping a casual eye out for one of these for quite a while and I finally found one!!! I managed to scoop up a 7521-40 with the easy load II head that has a really cool precision speed dial for almost nothing.
BUT! It is really, really loud. The drive makes this rumble/hum the whole time it's running, you can clearly hear it over the tank, over the TV, even over a big box window fan.
I was curious, is there any way to quiet it down? (I'm assuming not) but you never know.
Are there any of these units that are dead silent? I mean so quiet you could not hear it over a Tunze 6100 at 50% power?
Thank you,
Whiskey

My impression is for silent running you want a brushless unit, which is going to set you back bigger bucks (closer to 1k)

You will need to get an brushless motor like the 7523-60 to get it to be silent, but even that you will still hear a very faint hum while the drive is spinning.

I don't think there would be an issue doing that. Hopefully you don't have rats or mice in your attic that may take a liking to the tubing. Those pumps produce a lot of pressure and it should work fine though. As others have mentioned, a dampening box will help too if you wanted to keep it closer to the tank. The brushed models are typically pretty loud when the motor is rotating. Brushless are nearly silent though.
