Works great! I run a continuous recirculating hydroponic garden with a 30 gallon water reservoir. One of the nutrient mixes I use drops the pH to around 3.8 so I use this to raise it back up.I originally just added a "splash" to the reservoir but noticed the nutrients would percipitate out of the water immediately hit by the splash (which is a strong base). I then started pre-mixing the "splash" in a 3 gallon bucket of water and then pour that into my reservoir. This seems to keep the nutrient in solution as the pH difference isn't as extreme when it mixes in.

Matching product for ph Down. Very effective. Just a small splash moved the PH for my 700 gallon aquaponics tank about 0.4.In my 700 gallon aquaponics tank the quart size was used up in about one month. Apparently, the plants, at the early stages anyway,and the expensive tilapia food I'm using are pushing the PH down just a bit. I have purchased the gallon sized bottle of this along with5 pounds each calcium hydroxide and calcium carbonate. the potassium and calcium are both good for the plants and don't hurt the fish.

The ones complaining about this being weak want a pH of 14 lol. If you read the ingredients before you buy, potassium carbonate has a pH of around 11.5. This product is testing around 11.2. If you aren't happy with that then go buy some raw potassium carbonate. You don't need a pH of 14 for this product's use case, in fact you'll probably shock your plants into a quick death. This stuff stores for a while too so I can't imagine anyone getting a bad bottle.

I love the fact that it came a day earlier than expected during (covid19) I appreciate the fact that when using properly it allows me to control the desired range for plant nutrient uptake, it's safe to say bv that I'm team General organics/hydroponics, I've noticed that more PH⬆️ is used during the flowering stage than ever, well with the humidifier nutrients that I use.

This stuff uses potassium carbonate of which I'm not a big fan as I don't want any of those carbonates in my reservoir. I have since replaced this product with 2 molar strength potassium hydroxide that I mix up myself (11.2g KOH flakes into 100ml of distilled water) to get roughly the same neutralizing effect per teaspoon.

This product is excellent, but the shipping was inappropriate (caustic liquids, unlabeled, dripping, via USPS??!!). Disposed of almost immediatelyBUTThe seller's customer service team made it rite with a commendable responsiveness, so that was at at least a small win for my experience.

Very small amount to UP the pH of my RO water and Botncr food. Also would recommend the GH pH test kit which comes with up and down as well as the reliable test and piper. Piper is needed for the very small amounts for one Gal. of water. Don't Try Baking Soda! LOL...

Easy PH adjustment. Takes a little more to move PH up than bringing it down. Much more precise dosage than baking soda. This is easy to use with a bulb dropper and you get the the PH you need for your precious plants. I recommend.

Great stuff for raising your PH but if you are doing canabis just buy General Hydroponics Armor Si. Not only will it benefit your plant by adding silicon but it raises the PH. I no longer need the PH up since adding the Armor Si.

Takes very little to increase the pH (talking ml of pH UP) and does what it's supposed to do. If my pH is 5.0 in a 30 gal tank and need to get to 5.7, I'll prob use like 5-7 ml of this to get it right.
