Flairform pH Down (250ml / 1L)

What is Flairform pH Down and how does it work?

Flairform pH Down is a citric acid-based solution used to lower the pH of water or nutrient mixes in hydroponics and gardening. It’s designed as a safer, non-corrosive alternative to strong acids, helping maintain optimal pH for nutrient availability.

When should I use pH Down instead of pH Up?

Use Flairform pH Down when your solution’s pH is too high (alkaline). If the pH is below your target range, you’ll need a pH Up product instead. Always adjust pH after mixing all nutrients and additives.

How do I use Flairform pH Down properly?

Mix your nutrients first, then slowly add a tiny pre-diluted dose of Flairform pH Down to the reservoir. Let it circulate, wait a few minutes, and re-test. Repeat as needed to hit your target pH without overshooting.

How much Flairform pH Down should I use?

Dosing depends on your starting pH, water hardness, and tank size. Start with a very small amount (e.g., 1 mL per 50 L), mix well, and test. Hard water needs more adjustment; soft/RO water needs very little.

What systems and media is Flairform pH Down safe to use with?

Flairform pH Down works well in hydroponic systems, coco/perlite, and soil. It’s also suitable for recirculating setups like RDWC and NFT, though frequent pH checks are recommended. For ponds or aquaponics, dose cautiously and monitor closely.

What pH range should I aim for with Flairform pH Down?

In hydroponics, 5.5–6.2 is typical. Coco prefers 5.8–6.2, while soil grows usually aim for mid-6s. Focus on consistency more than hitting an exact number.

Why does my pH keep drifting even after using Flairform pH Down?

Common causes include hard water, algae, light exposure, poor reservoir hygiene, and temperature swings. Fixing these issues can reduce daily pH corrections.

Do I need a pH meter to use Flairform pH Down?

Yes. A properly calibrated pH meter ensures accurate adjustments. Check calibration monthly or more often if readings seem off or you're adjusting frequently.

Is Flairform pH Down safe to handle?

It's less corrosive than many acids but still acidic. Wear gloves and eye protection during regular use. Rinse skin or eyes immediately with water if contact occurs.

How should I store Flairform pH Down?

Store it upright in a cool, dry place away from direct sunlight, children, and incompatible chemicals. Don’t pour unused diluted product back into the bottle to avoid contamination.

Does Flairform pH Down expire?

It’s stable when stored properly, but exposure to air or contamination can affect performance over time. Always keep the cap tightly sealed between uses.

What sizes are available, and which should I buy?

Flairform pH Down is sold in sizes like 250 mL, 1 L, and larger. Choose smaller bottles for occasional hand-watering and larger ones if you run multiple systems or large reservoirs.
