Is there a way to shut off the display on the 7523-80 digital?

Why would you want to?

scuzy · 12/16/2016, 11:21 AM

There is no point to have it on at all times.

Yeah, I would like to to know a way to turn off the display also.
I put a piece of black tape over it for the time being.

tkeracer619 · 12/16/2016, 01:35 PM

Afaik there isn't a display blackout.

Anybody with a large mixed reef tank run under 100rpm? I'm setting up a 300g and and looking at a unit that can do .1-100rpm.

Your might find this link helpful. I really depends on the amount of Alk the tank uses. I have a 180 SPS tank and use aabout 1.2 dKH/ day and pump at around 40 ml

Thanks for the reply. Can you repost the link? I don't see I. What tubing are you using on your rig and how many ml are you getting per rpm?

Oops forgot to paste it. It is there now.

vhuang168 · 12/16/2016, 02:50 PM

Flow rates for all the tubing. We normally use LS/17

https://www.coleparmer.com/tech-arti...tubing-options

So hkgar's 40 ml would require about 14 rpms.

Keep in mind that a 0.1-100 pump will be louder than a 6-600 pump at the same rpms

I don't know anyone running 100rpm. The motor is the same in both versions but the gearing is different. At equal rpms a 1to100 rpm drive is spinning the motor 6x faster than a 6 to 600

eddiem · 12/21/2016, 07:31 PM

Where does the Masterflex go? ...On the feed line to the reactor or on the effluent line leaving the reactor? If on the feed, as I suspect, does the effluent flow wide open or are people using needle valves? I read through over 50 pages of this thread and I can't find an answer.

Thanks

souk · 12/21/2016, 08:10 PM

Either will do and I have mine set to feed. The beauty of using a pump like the cole is to eliminate the needle valve so it's wide open to avoid any clogs.

Mine feeds the reactor. The masterflex replaces the needle valve and provides superior accuracy.

You might searc the thread for pull to see discussions about leaving the pump side. The methods are generally referred to in this thread as push and pull and it has been brought up a number of times.

someone is selling a 7520-35 used without a pump head, are these worth it? $250 bucks. Needs new bearings.

I'd pass. Especially if it needs bearings and a head.

Thanks. What do you think of this one?

http://www.ebay.ca/itm/COLE-PARMER-M...kAAOSwHoFXqg~r

Do i need anything else to run it?

I'd pass on that one too. Too low of of max flow rate and not an ideal pump.

eddiem · 12/30/2016, 04:40 PM

After months of searching and the help of this thread, I finally scored a Masterflex 07575-30 with a 7518-60 head. Thank you!

Question
Re Continuous water change
How about a smaller fixed low rpm masterflex pump with 2 adjustable easy load heads ? Continuous
I was thinking 2 RPM with LS17= 5.6 ml per min... about 2 gallons per day and 60 gallons per month
