General Hydroponics PRO pH Down - 6 Gal

Bring High Reservoir pH Back Into Range - 6 Gal Container

Nutrient solution that drifts too high can limit how well plants take up nutrients. General Hydroponics PRO pH Down is an acidic liquid that lowers solution pH, so you can correct a reservoir and keep conditions consistent. Its safety data lists phosphoric acid and citric acid as components.

The 6 Gal container suits growers who adjust many reservoirs or run larger hydroponic systems, where a small bottle empties quickly. Home growers with a single small system may prefer a smaller size, since this container is sold as one unit.

Key Features & Benefits

• Lowers solution pH — corrects water or nutrient mixes that test too high.
• Liquid form — soluble in water, so it mixes into a reservoir readily.
• Phosphoric and citric acid blend — the safety data sheet lists both as components.
• 6 Gal container — fewer reorders for frequent adjustment.

Who Should Use General Hydroponics PRO pH Down

Growers running hydroponic systems, reservoirs or fertigation setups who need to lower pH during vegetative growth or flowering. The large container fits commercial and high-volume users.

Frequently Asked Questions

Q: What does pH Down do?
A: It is an acidic liquid that lowers the pH of water or nutrient solution. Use it when a reading comes in above your target range.

Q: How much should I add?
A: Start with a small amount, mix thoroughly and retest. Water and nutrient mixes differ in buffering, so add in small steps until you reach your target.

Q: Is it safe to handle?
A: It is a corrosive product. The safety data sheet warns that it causes severe skin burns and eye damage, so wear gloves and eye protection and read the sheet before use.

Q: What is pH?
A: pH measures how acidic or alkaline a solution is. Hydroponic growers monitor it because it affects nutrient availability to roots.

Q: Does it dissolve in water?
A: Yes, the safety data sheet lists it as soluble in water. Stir the reservoir after adding it so the solution is even before you test.
