Frequently Asked Questions About Hydra Crystal

Is Hydra Crystal safe to use with fish and wildlife?
Hydra Crystal is harmless to fish and wildlife it rapidly flocculates and clears green and cloudy water and is safe for your pets to drink from the water.

How long does it take to work?
Within 30 minutes the Hydra Crystal will start clearing your water - a large water body will take about 24 hours to clear. The mineral structure of Hydra Crystal will sink to the bottom where your filtration system will remove it. If no filter is present then the particles will slowly disintegrate over time at the bottom.

Can I use this water for irrigation?
It is safe to use this water on plants and grass, there is no waiting time before using the water.

How long to leave before retreating (if it does not clear on the first application)?
Hydra Crystal will usually clear the green algae cells on its first application, but in cases of heavy investation a second treatment may be necessary. In 2nd treatment use at the initial dosage rate and you can retreat water after 24 hours.

When I added Crystal my water went brown!
When you add Hydra Crystal to water, the water goes brown initially this is due to the minerals in the product absorbing the algae, this is quite harmless and will clear once all the algae has been absorbed.

How much time between Treatments?
This will depend on your individual pond's balance:

  1. Number of fish to size of water body
  2. Amount of food being given to fish
  3. Whether fertilizer run off is coming from surrounding ground / grass areas
  4. Amount of plant life in water body to absorb nutrients i.e. phosphates, nitrates etc.
  5. Each water body is a unique eco system - once it is in balance it should not be necessary to add additional add additional Hydra Crystal

Overdosing
While Hydra Crystal is a very safe product we would not recommend overdosing as you would be wasting your money, however we have tested it at 1:4,000 and found that it was still safe to aquatic life. Once the water is clear there is no need to re-dose unless you are using the maintenance program.
