## Description

Bluelab CONTPHCON pH Controller Connect with Monitoring, Dosing and Data Logging of Solution pH Levels (Connect Stick not Included)

Review: I wouldn't recommend this to someone just starting out. I would at least get an idea of how your system behaves first (maybe half a grow) and then grab one of these. With that being said this thing is amazing! I have two for two DWC setups and it saves me so much time. My PH always tends to drop. This thing keeps at a solid 5.9 without a blip. I was ph'ing my system 2x a day. Such a hassle. I haven't ph'd since I bought this. I wish I would have bought it years ago. Just set it where you want your ph, how many seconds of solution you want it to dose, and how long to wait before dosing again. I have mine set for 2sec on and 5 min off. Works great. It never overshoots. I can put it online but haven't found the need to. I generally don't adjust my ph to different points often. Nice feature though. My only complaint is Bluelab didn't make an option that offered up and down. I never have to ph down now, but it would be nice to have total control. I've run nutrients that sway up at first and then hard down later. If you know how your system behaves and you want more time for other things this is a great option. Plus plants enjoy a stable ph. Worth the money.
Review: Wish I had this year's ago in my reef tanks lol Great for hydroponics

## Questions & Answers

**Q: What’s the length of the tubing provided?**
A: about 8 inches or so. How long are you needing it to be?

**Q: Correct that probes can't be completely submerged? Just the tip can be?**
A: On the Connect version I received, you can fully submerge the probes.  However, they come with a suction cup that attaches to the cable to place wherever you want to stick them.

**Q: Does this controller work without the connect stick?**
A: Lets clarify a few things.. 1) YES, it will operate perfectly fine without the connect stick, it just wont log any data from the controller nor will you be able to login to the cloud to view the controllers data log.  For that to happen, you need a connect USB stick. 2) It does automatically adjust the ph just fine, if a alarm condition is present it will stop dosing, and there are other conditions that will prohibit it from dosing automatically. From the manual: Use ‘mode’ to select the pH controller connect function. ‘Monitor’ mode shows the current solution pH reading. It is the factory default setting. ‘Control’ mode allows the controller to dose pH stock solution to the set values. Dosing will NOT occur when:•   The pH controller connect is in ‘monitor’ mode•   The pH controller connect is in an alarm state•   If the pH controller connect senses dosing is not having an effect on the system (after 15 dose cycles)•   The solution temperature is above 50 °C / 122 °F, or below 0 °C / 32 °FAlso, you set your dosing amount, ie, 1 second on dosing, wait a hour, then re-dose if PH level is still not correct. Im not sure what the previous comment is talking about the unit not auto dosing but he may want to read the manual.

**Q: Can this be connected to both PH up and Down simultaneously?**
A: No, just one.  It cannot handle both up and down at the same time but it can be set to use either one of them.  These things rock!
