If you want your second stage to stay exactly the same throughout the bottle you need to swap the single stage regulator on the AP out for a two stage. The Harris two stage 15psi regulator is the one you want for that. It's another $250-300. I look at my reg once in a while and adjust the pressure if necessary, it is maybe an adjustment a month at most. If you are leaving the reg on and not using a controller to pulse it, the regulator will get to temp after a day and usually stay there. It creeps as the bottle pressure drops and will also fluctuate based on the temperature of its internal spring.
The gauges AP uses are less than perfect. The actual number does not matter but yes due to the mechanics of a single stage reg it is more accurate at higher pressures. Some regs are more susceptible to this. The one you have may be sensitive. They are reliable but he is pulling your leg if he says they don't run across issues from time to time. "Not using them correctly" = . Can you post some pics? How long is the run and what kind of tubing are you using? If you run the reg wide open, it is my observation that as the media dissolves the chamber ph decreases simply dissolving more media. You may find that it runs great how you have it setup but if you cannot get the ph lower maybe it is best if we address that as well? I've always run my AP reg between 7~15psi but my final goal is ~10psi x whatever the counter is doing.

Two Stage Regulator
The two stage regulator I like to use is the Harris 9200-15-320
Cheapest I've found it was $300 online at weldingsupply but I am sure someone can find a better deal. Post it if you do please It is big and if you aren't already strapping your bottle you will need to with this reg (you should be anyways). I plan on getting one when I find a good used one but until then I am using the AP single stage.

The bummer is that I don't believe the AP controller is removable unless you buy that version to begin with. So it's a two stage regulator AND another AP controller to swap out the setup. I was very close to buying them separately in the first place. It appears that after going to 7psi things are much more stable. I am seeing reactor pH in the 6.48 to 6.55 range with far fewer pH controller cycles happening. Going to the higher pressure appears to have been the magic juju. I do wish my reactor was more efficient at forcing the C02 into the effluent though. |

You can remove the black box from the regulator body. No problems there. Like I said it is a nice to have. For most of us it is insignificant as long as we look at that gauge once in a blue moon.

Sounds like you are cutting the gas off too soon. Try setting the cut off point .2 below what it is set at now. Mine is set to cut of at 6.1.

Bad regulator?
My ph chart the last 24 hours
The high spike is from when I calibrated the probe. Apparently last night at about 10 PM my reactor ph start diving. Apex shuts down the Aquarium Plants regulator at 6.3 so it never went lower than that. Low side pressure was 7, flow rate 10 ml/minute, bubble rate 8 seconds. Nothing changed, just the PH start going down. I now have the low PSI at 4 and the rate 9.5 seconds and at about 6.6. The only ting I can think of that would effect ph would be the size of the bubble. The rate didn't change as I timed the bubbles this AM and it match the setting. Possibly the tank is starting to run low? Regulator may be bad? It is the standard set of guages that came with the regulator.

This thread has been great and very helpful. I was a little skeptical at first about spending so much on a feed pump, but now that I have I love my MasterFlex Pumps as in plural lol. I ended up picking up two.
I was originally feeding my GEO 510 off my return with a needle valve and it was never really consistent. I have been running this 7523-90 and it has been rock solid, really set it and forget it. [IMG][/IMG] I ended up winning another one, and I was originally just going to sell it but these things are so cool I was trying think of another use for it, and I was thinking about eventually getting a Kalk stirrer and feeding the Kalk stirrer with it rather than using my ATO, I figured that would give me so much more safety and control. Its so cool Id think I would hate to sell it now. MY 7575-00. [IMG][/IMG]

Reefer comes over for a frag and sees it. "What kind of pump is that?" You respond "Don't worry about it man, you can't get one."

What did you get the stainless unit for those things are big bucks direct from Masterflex!

PS This thread should be sticky. I send a lot of members with CA reactor question here ans I am convinced it is the only way to run a CA reactor. Great thread

Help with easy load head
I have an Easy Load head, model 7518-00, on my pump that makes a clicking sound 3 times with each revolution. I know it is coming from the rollers, but does anyone have an idea what is wrong and how to fix it?

I assumed that cadence clicking sound was normal... once in a while I get an irregular squeak. since my masterflex is in a remote closet the sound is not so much of an issue, but if it were front and center I can see how the sound would be unnerving.
will be interested in response to this as well. |

+2 I am going to give this a try also, slight clicking at lower RPM has been bothering me for awhile, but these things are so much quieter than any other pump I have just wrote it off, but if there is a easy fix I am in! I used a silicone spray lubricant on the squeeky wheel thing and it fixed it right away. I had a can of garage door silicone lubricant and this is what I used. I sure diddn't take much...a very slight tap on the sprayer and that was it.

Seems to have fixed the problem. I used about 3 inches of teflon tape and folded it over a few times and put over the tab and all is quieter. Not perfectly quiet but much better. Maybe a little more tape next time.

The tape will squish down over time so if you hear it again, just remove the head and add some more tape. |

Awesome! Glad to hear that problem was resolved and it was just a probe.
If you have a head that clicks often its from extra slack in the bearings or in the shaft area where it meets the drive. The rollers themselves are very durable, especially the stainless ones. I use this stuff between my head and drive. It has a lot of uses (like pesky rear view mirrors that want to move around with your subwoofer). One package is enough for a lifetime. http://www.amazon.com/3M-08578-Black.../dp/B000PEZ1L4 This is definitely the only way I would run a reactor, I made this thread so you guys could enjoy the successes I have. Glad it has had such positive results!
