Before purchasing this brand of pH Down I did some research as to figure out what type would be most worth the money, and I learned some what I feel to be very important things. Another brand name of pH Down is 5-TIMES WEAKER than he General Hydroponics brand, and while they do not state what the percentage of dilution is, I have learned that it is "Food Grade". I also stumbled across some "Pharmaceutical Grade" and wasn't sure which one was more worth the money... But if you look at all your hydroponic equipment everything is made to "Food Grade" standards, so why shouldn't your pH Down also be? When I did more research I also learned that this is the number #1 most talked about brand everywhere I looked and most recommended by other gardeners all over the internet, so that helped influence my choice towards this brand.

As far as the size of the bottle and the amount you need... This bottle should last me a couple of years, but I just bought some much smaller bottles and will ration it out into smaller bottles to avoid contaminating the 1-gallon bottle, and from the smaller bottle I can use a pipette to add the drips of pH Down to my water to bring the pH Down. Overall I am very happy with the 1-gallon size bottle and will either continue to buy it in this size or in the dry powder form when it becomes available again at the end of 2015, as I am told they had a manufacturing issue with it and won't have it back up being sold again until then.

It works you need a ph meter, it depends on the nutrients you use. And yes every couple days you will have to adjust it... why because your plants are eating food drinking water and as your nutrients level goes down your pH level will start to raise. Rule of thumb when you need to use pH Up. It means it's time to change your tank rule of thumb no more than two weeks and you should be changing your nutrients for healthy plants. It works as designed the few people that say they wish it lasted longer while your plants eating food that's why your pH level changed slept a good thing. With what I'm using I have a 50 gallon tank. After I mix my nutrients roughly 4 tablespoons is all I need in about every 2 or 3 Days 1 tbsp to keep my pH level on balance. Very important to keep your pH if it's too low you've going to deprive your plants and if it's too high you're going to deprive your plants of much-needed nutrients your lock out there food. Can you buy a cheaper yes of course she can like anyting

I purchase 1 gal of pH Down and 1 gal pH Up. The two arrived together in a plastic bag in the same box. Half the box was completed saturated. Turns out almost half the UP had leaked out. Some was still in the bag but enough had escaped to saturate the box to the point of crumbing. The bottle had been mashed in but the seal on the lid appeared fine, so I assume there must have been a tiny puncture either in the lid or the bottle itself. I have used the product before and it works great. However, I was really disappointed in the shipping damage.

Bulk size of PH adjuster to reduce the acidic content of your plant growing soil in order to opitmize conditions and provide the best outcome for your plants. It can be used on a host of different plants, flowers, shrub and trees. It is mixed in a large amount water and then use your PH meter to test before watering. This size will last a long time and is easy to store. Use this sparingly to make gradual adjustments so you avoid shocking your plants. Easy to store and handle. I keep it on hand to us over and over again.

I use this in my indoor hydroponics set up and the large size is great as my water always needs adjusted down. This gallon has lasted me about 6 months, but i noticed after about 2 months, i was putting in more product to adjust the pH the same amount. Nothing has changed in terms of the amount of water or size of container im using, so i cant imagine what would be causing this other than the deterioration of the product over time

As usual PH Down does not disappoint. We've used this brand for years but if I can remember right this is the first time we have bought it by the gallon. It arrived safe and secure and it's doing it's job so you can't really ask for better. Perfect for all of your hydro projects!

This is Phosphoric Acid NOT Citric acid! ...I was not able to find that until it arrived and I turned it around and read the label ingredients! ...I recommend they make it better known in big bold text in the description! ...so you can know right away before you buy! ...I was so worried I was gonna end up with more citric acid which I already had! ...price is a little high!

Had my dirt test for PH. Grass did not look that healthy. My pH was over 8. 8.5. 7 should be the ideal pH reading. I use this product maybe four days ago. Tested my dirt today. It's reading is 7pH. Luckily the dirt got plenty of water after I sprayed the product on my grass. It seems to fast. But I don't have a clue how it's supposed to work. But it seems like it worked.

Used General Hydroponics PH down as well as Botanicares PH down. GH will lower PH considerably faster while adding very minimal ppms. Botanicare's PH down took up to 5 times as much and added tons of ppms to the reservoir. I also recommend General Hydroponics Flora nutrient series, very simple feeding program that is extremely budget friendly with minimal upkeep.
