STOPBLOC

Advanced Anti-Blockage Solution

A high-performance hydroponic system is only as good as its narrowest point. When salt build-up, algae, and mineral scale choke your drippers, your plants are the first to suffer. Stop Bloc is engineered to keep your system flowing at peak efficiency, ensuring every drop of nutrition reaches the root zone.

▶ Dissolves Mineral Scale: Prevents calcium sulfate "fallout" and keeps nutrients fully soluble.
▶ Combats Bio-Films: Stops algae and slimes from coating the inside of your feed lines.
▶ Protects Your Hardware: Reduces wear on pumps and filters by eliminating insoluble debris.

While maintaining a pH below 6.5 and using quality filters are vital, StopBloc provides the chemical insurance you need to automate with confidence.

Whether you’re running a complex recirculating system or a standard run-to-waste setup, StopBloc ensures that water "hardness" never turns into a harvest-killing blockage.

Directions for Use

Stop Bloc is compatible with all types of hydroponic nutrients and systems. For best results, incorporate it into your standard reservoir maintenance:

Standard Dosage: Add 0.2ml per Litre of nutrient solution.
Application: Add directly to the nutrient reservoir after all other fertilisers and additives have been mixed.
Frequency: Use with every reservoir change or top-up to maintain constant protection.
