ph controller and doser

So I'm running D.T.W hydroponics with canna series nutrients in a 100L tank.. my problem is ph I ph the tank at 5.8 and it will stay for about 12 hours then it starts to slowly rise so this isn't really a huge deAL just keep ph it right ...well ya until I go out on vacation for a week and Noone is there to ph my tank lol ok so question any body have experience with these 2 products I have a milwaukee ph pen and it wors awsome but the price difference between the two controllers has me thinking about quality and reliability unless of course no one's ever had problems with it then it wud be nice to save a buck lol well done with my rant now to post these links so u know wth I'm talking about lol

Okay you are checking the pH. How about the EC/PPM? Before you go ordering all that bullshit.

By the way you need to grow in soil if you want to go away for a week and not come back to a frigging mess.

Yah I'm checking the e.c I'm not a noob and I'm in coco not soil I already left for a week and had my brother come and pH my res everything is automated except for that .. not looking for growing advice looking for someone who's knows a think or two about these controler thanks

The blue lab one is legit. Only controls up or down not both just an FYI. Works great though I use in my dwc

Dope thanks man peace and respect

I have one, works like a charm. Matter of fact I have 2 of em.

Directions on how to put together are not the greatest and the tube size is a pain to get onto the weight/ filter that resides in your PH solution.
I'm using battery acid, 1 cup per gal of water. Works much better than any other PH down I have used.
When I mix a new nutrient solution I end up using roughly 260 gallons of water so I need a little more concentrated solution. I could 1 gal of PHdown from GH and barely move it.

If I was just in a couple of 5 gal buckets I would just delute the mix even more.
