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

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.

Wish I had this year's ago in my reef tanks lol Great for hydroponics

después de un mes, la sonda de ph falló.

Hallo...der Artikel ist mit halb offen und verbeulten Karton angekommen, die Teile sind soweit in Ordnung, nur ein bisschen unwohl ist mir wo ich die PH Sonde aus dem Karton geholt habe und gesehen hab das da nur ganz wenig Flüssigkeit in den kleinen PH Behälter ist. Der Karton lag auf der Seite im Packetshop.Ich habe es auf die Seite gedreht und die Sonde war NICHT mit Flüssigkeit bedeckt. Ich weiß jetzt nicht ob die Sonde funktioniert, werde am Wochenende alles in Betrieb nehmen und kalibrieren. Ich weiß jetzt nicht ob ich die Sonde umtauschen soll oder nicht.

Thank you
