General Hydroponics PRO pH Down - 55 Gal - 23 x 23 x 35-in

Lower Solution pH at Commercial Scale - 55 Gal

Nutrient solution that drifts out of range limits how well plants take up what you feed them. General Hydroponics PRO pH Down uses non-mineral acids to bring pH down without adding nutrient value the way phosphoric acid does. It is highly concentrated, so a little goes a long way.

This 55 Gal size is built for commercial growers who adjust large reservoirs or irrigation water every day. Smaller growers can look at the smaller sizes in the range.

Key Features & Benefits

• Non-mineral acids — adjusts pH without adding nutrient value to your recipe.
• Non-corrosive and non-caustic — handling is easier than with mineral-based adjusters.
• Zero HMIS ratings — the distributor lists a zero score in every safety category.
• Highly concentrated — adjusts large volumes with small additions.
• Commercial size — one 55 Gal unit supports high-volume hydroponic and liquid-feed programs.

Who Should Use General Hydroponics PRO pH Down

Commercial growers running large hydroponic systems, fertigation or liquid-feed programs will get the most from this size. It suits anyone who wants to lower pH without altering the nutrient balance.

Frequently Asked Questions

Q: How do I use pH Down?
A: Mix your nutrients into fresh water first. Then add pH Down a little at a time, stir, and test. Repeat until you reach your target pH.

Q: Why add nutrients before adjusting pH?
A: Nutrients change the solution pH when they dissolve. Adjusting afterward gives you a reading that reflects the final mix.

Q: Does it add nutrients to my solution?
A: No. It uses non-mineral acids, so it does not add nutrient value like phosphoric acid does.

Q: What does non-caustic mean?
A: It means the product is not strongly alkaline and does not burn like caustic substances. This product is listed as both non-caustic and non-corrosive.

Q: Where can I find safety information?
A: Safety data sheets for pH Down are available from the manufacturer. Review one before handling large volumes and follow local rules.

Q: Is this size right for a small garden?
A: Usually not. A 55 Gal unit is intended for commercial volumes, and a smaller size is more practical for a home garden.
