I recently joined the club by getting a good condition 7523-80 Digital Peristaltic Pump off ebay several months ago. I ran it with LS17 pharmed tubing for maybe a couple of months then the unit began throwing error 12 and error 14 which indicates the pump is stalled. I contacted cole parmer support and they suggested I replace the gear kit which I paid $90 shipped and that didn't fix the issue. Now in order to repair it I have to spend $800 to ship it to them which I'm very on the fence with doing so.
As an alternative I got a second 7550-60 pump off ebay again and that unit runs for maybe an hour before I get a "fault" error on the LCD screen. I have to repeatedly hit the start button again to get the pump going. So now I'm shopping for third pump to see if I have better luck. I hear from most parmer owners that the units are rock solid but that has not been my experience. Maybe it's just user error on my part? I wonder if anyone else has had as much trouble as I with these pumps.

Shipping can be rough on them if the controller isn't packaged well.
If you pull out the gear set on the one that is throwing the stall error can you spin the motor freely? Does it work with the gear set removed? Sometimes the bearings go bad and need replacing. Can you return the second one? This is one reason I always want people to get a complete unit, run it from day one even if they don't use it on the tank right away. If you make it through the return period without any faults you are usually good to go for a long time. Most of the people selling these don't really know how to fully test them and don't know their history.

Anybody take the box off of their AP regulator and connect it to a true dual stage? I have a dual stage airgas reg. Is there a benefit to this? Is it literally as simple as unscrew from the AP ref and screw into the airgas reg?

Can we sticky or make a new thread on how to actually set up and fine tune.
How to increase/decrease alk in tank depending on the situation. What increasing/decreasing the effluent will do. What increasing/decreasing ph will do. All in relation to the tank. Best place to start for a new reactor and how to adjust from there. I know the answers are here but hard to find in a 2800 post thread. Thanks guys! |

The first few posts in this thread tell you what you need to know. Every tank will be the same, tank has x demand, you adjust gas and effluent until demand is met. The reactor setups can vary brand to brand but the actual tuning is the same. That is what is brilliant about the setup, very easy to dial in, and very precise/predictable.

Maybe start at xbubbles and y ml effluent. Or stsrt at z ph and y ml. Then to increase alk of the system decrease ph or increase ml. To decrease alk in tank increase ph or decrease ml. (or both) Something like that. I guess what I'm really asking is that I don't fully understand how to completely fine tune a system and what to do when demand increases or decrease in the tank.

I've been struggling with steady effluent for a while and after a ton of reading on using Dos, Kangaroo, Masterflex, etc I decided to pull the trigger and join the club. Grabbed a 7523-70 with an easy load. Hopefully this was the right decision. Already have a AP reg set and a lifereef calcium reactor. wooh!

Question: Since I purchased a 1.6-100 RPM brushless motor, am I better off going with bigger size tubing to cut back on how fast I have to run the motor and how noisy it gets or should I be ok with the 1/4" tubing?

Im having the hardest time keeping bubbles from collecting in my reactor.
I can completely purge the reactor for what I can tell but after a few hours i have a big bubble at the top and my recirc pump is pumping a big mixtue of air and water. Initially I was doing effluent at 40ml ive uped it to 80. But of course with the increase in rate i have to increase the bpm or size. Im using the carbon doser and a geo 612x2 reactor |

A) You have a vacuum leak on the circulation pump or it’s intake connection to the reactor or intake side of the Masterflex pump. B) You are picking up microbubbles from inside your sump via the intake tubing for the Masterflex pump C) You are putting in more Co2 than the output rate of your Masterflex. It might help to recalibrate your pH probe to be certain that’s not part of the issue. I run at 65ml/min on my Masterflex and 1 bubble every 3.5 seconds at 3PSI to maintain about 6.75 pH in my reactor. If you have too much Co2 going in compared the flow rate of the Masterflex then you will build upon excess gas in the reactor and if your pH probe isn’t calibrated properly then you will get erroneous pH readings leading you to add too much gas. Then you have a double edge sword because the excess gas in the reactor will create bubbles in the probe tip that impact the pH readings inside the reactor. Shaking the reactor when purging the air/gas will help remedy that but you should double check your probe calibration with some pH 7 solution to see what the probe reads.

Looking to hop on the peristaltic train... do either of these look like a good deal?

Questions on L/S7551-00
I’m wondering if anyone can help me on a few questions. I’ve got an L/S 7551 that I have been using to feed my deltec calcium reactor (pf501) with an aquarium plants carbon doser. I had a power surge which affected the pump and now it blows a fuse every time I power it on. Questions:
1. Does anyone have a secondhand circuit board I could buy to replace the one I have? 2. I’ve been using a dosing pump in the interim. One thing I have liked is that my pH is no longer depressed (even with co2 scrubber it was constantly low). Has anyone used one of these pumps as a dosing pump instead of with a calcium reactor? 3. What would I need to do to convert my l/s pump to a multichannel pump? I have an easy load head would I need different heads or can I stack multiple easy load heads. Do the heads run independently? |

For 2, are you running the pump like a traditional dosing pump as an on/off schedule, or constantly? Curious what you’re seeing related to pH as I have a scrubber on my skimmer and still get .3 ph swings from 7.9-8.2ish max. As far as using it as a dosing pump, guess it depends on what and how much you need to dose as it’d be continuous, unless you’re switching power on and off to it from an apex.
For 3, if there’s only one motor, not sure how the heads could run independently. |

for 3 you can stack upto 4 heads (maybe more but I've seen 4 stacked) the issue is that they are all driven from the same moter and are all driven at the same time and the same amount so you couldn't use that setup as a multi-channel doser like the ones with multiple heads.

Ah ok, that is what I thought the problem might be, so that rules that option out. |

Planing to setup my new geos 6x18 calcium reactor with a secondary chamber. Its a little too big for my tank which is 90 gallons acro only system but I have plans to upgrade later this year .
Got aquarium plants regulator and waiting to get my masterflex pump. I know people often recommend to pull water from the reactor than to push it with masterflex. Stupid question but please help me understand how do you pull water ? Do you pull the water with masterflex pump by connecting to the input of the masterflex pump to the effluent line and then have a maxijet to push water into the reactor ? I believe i should match the masterflex rate to the feed pump ? Sorry for such basic question ! Regards, Abhishek |
