![]() Īs my country is not as easy to look for 2nd hand CP pump yet I am still working on my latest offer from the only local 2nd hand dealer of which I posted the photos earlier. I would like to thanks Slief for his very supportive assistance in my find for the right pump. is there a big difference with bubble size? so when i adjust the bubble rate to less frequent, do i need to change the size of the bubbles with the AP Carbon Doser? or do i just adjust the bubbles and the flow? right now i think the PSI for the bubble making (i dont know what to call it. ![]() It takes a bit of futzing but once you find the sweet spot, the reactor pH should be extremely stable to the point that your Apex won't have to intervene. I'd try to target 6.7 inside your reactor by balancing your Co2 bubble rate. Also, 6.5 reactor pH is kind of on the low side even for Reborn media. You just need to adjust your water flow up or down and your Co2 bubble rate up or down until you find the sweet spot. I've found that you get a balance in pH that is precise enough that the Apex doesn't even have to shut the Co2 solenoid off. I would try to balance it out with the Co2 bubble rate and the cole parmer flow. You can decrease the gap between on and off but I think your program is OK. The thing i notice is that my pHR will drop till it hits 6.5 and then shut off until it goes back up to 6.7 then on then off then on then off. ![]() here is my apex CO2 coding (I renamed my pH2 to pHR because it wasnt saving with pH2 for some reason): i will test again tonight but i am please so far. ![]() i tested alk last night and it was 8.3 and this morning it was 8.3. the CO2 is running at about 1 bubble every 3 seconds and my effluent flow is at 30 ml. I hooked it all up and i am very surprised that there is no more air bubbling. i know it is a cluster f so i am going to home depot and installing another shelf to put all this stuff on tonight. GREAT NEWS!!! I am very please to say that it is plumbed into my tank! and i am very very pleased that I am yet to deal with the air getting trapped in the top of the system like i anticipated, since apparently GEO reactors have this issue.įirst off. If however that was the case, your reactor pH would be very very low. Another potential source or air is if you are adding to much Co2 for the amount of water flow through the reactor. That should expose the source of the leak in a hurry. If you have a valve on the effluent line, you could close it to pressurize the reactor. To find the leak, you could swap the lines around so the Masterflex is pushing the water through. This assuming you have the Masterflex pump pulling through the reactor instead of pushing. If you get the air out and it continues to come back, you likely have a leak somewhere in your reactor system. Typically you should run the reactor for at least 24 hours without the Co2 on to purge the air. Is there supposed to be any air at all in a running calcium reactor? Mine seems to be working but there is air/gas being recirculated through it. Let me know when you get it back together. Glad to help Janet! It was a pleasure speaking with you as well. will grease it up and put it back together. Whats Included: 120/230 VAC power adapter with communications cable 32929-89 and NIST-traceable calibration report supplied by the manufacturer.Ok. For portable flow metering applications, order the battery pack listed under accessories. Order set point control modules separately from the table. Flow set point is established with keypad, the optional set point control module, a 0 to 5 V signal, or an RS-232 input signal. Flow controllers feature an integrated PID to direct the unit’s response to process changes. The 0 to 5 VDC output allows transmission of the flow value to a remote display, recorder, or controller regulating a valve or pump. An integrated keypad around the display is all that is required to program the unit for service. As compared to thermal mass technologies, the LFE design provides an ultrafast response within 10 milliseconds and offers “instant on” with no warm-up time. Because the flow element makes the flow stream laminar, placement in the process does not require straight pipe runs upstream or downstream of the meter, greatly simplifying installation. These meters measure flow via pressure drop across a laminar flow element (LFE). Models with 4 to 20 mA output or totalizer are available.100 to 1 turndown with ranges of 1 SCCM full-scale up to 1000 SLPM.Measure 30 standard gases-user selectable from display.Accuracy of ☐.8% of reading ☐.2% full-scale repeatability of ☐.2%.Versatility and high accuracy from a laminar-based mass flow controller.
