Frequently Asked Questions
Filter Start Gel should be used to kick-start brand new filters, or existing filters which have changed to brand new biological media. Pour the gel directly over the media. Pure Pond is a maintenance product which can be used regularly on new and established ponds to help keep water clear, reduce sludge, and keep populations or beneficial bacteria high, and intact. Pure Pond Bomb is a concentrated single dose of bacteria and enzymes. It can be used regularly, or if increasing fish load, washing filter media or replacing bacteria after the use of medications.
Yes, Gel to start your filter, Bomb for rapid bacteria replacement, and Pure Pond for regular addition and maintenance.
Yes, but a Bomb is better to drop straight into the pond as it is a large, gel ball. Pure Pond is small, so if you have water movement and fish it will travel around the pond, when it is best in a filter bag, in your filter, where it is contained. Gel should always be poured over filter media.
Ravenous Koi carp may eat Pure Pond if you offer it to them as if you were feeding them. Pure is only made up of beneficial bacteria and gel, but fish eating it should be discouraged.
Yes, Pure Pond shrinks as bacteria is released, and a small bead about 5mm in diameter will remain. It is safe, and can be removed, or left in the filter with other biological media. Pure Pond may crack, split and shrink as all the bacteria leaves the ball, but any remaining residue from the gel ball is also safe to leave in the pond system, or remove for aesthetic reasons.
Yes, Pure is 100% safe for fish, amphibians, invertebrates, bathing birds, and mammals visiting the pond to drink. But wash hands after use, keep out of reach of children and don’t ingest it.
Every Evolution Aqua stockist will either have them in stock, or can order them in.
Yes, Pure can be added to a wildlife pond or static water feature with no problems.
No, but the bacteria inside Pure is aerobic (oxygen demanding,) so adding far too much Pure may deplete a pond’s oxygen levels, unless sufficient water movement and aeration is in place.
If water temperature is below 10°C, Pure is less effective. As Pure contains natural bacteria and enzymes it will be more effective as temperatures rise.
Yes, the gel is fine to apply to the filter. You can add the Pure Pond bomb as part of the start up process of your pond.
PURE Pond has a shelf life of 2 years. There is a label on the bottom of the tub which clearly displays the expiry date and batch number. Please store all PURE products out of reach of children, in a safe place, with the lid tightly closed and in a cool dark place. Once opened, keep the lid tightly closed, and do not expose to frost or freezing temperatures.
No, you don't need to turn your UV off when dosing your pond with Pure Pond products (Pure Pond Balls and Pure Pond Bomb). You will need to turn it off when using the Pure Filter Start Gel and follow the directions as stated on the bottle.
Please follow question 3 for directions of use.
To maintain a biological equilibrium in the pond, we recommend dosing with Pure Pond balls once a month. This will also help to maintain clear water. For best results use when the water temperature is above 10°C.
A Pure Pond Bomb should be used as and when required to rapidly address biological and clarity issues. You cannot overdose the pond with Pure Pond Bomb, and you could continue to use Pure Pond Bombs repeatedly if you prefer. However we recommend, for ongoing monthly maintenance, using Pure Pond balls to keep ammonia and nitrite at bay, and maintain clear water.
Yes, you should be find to do so.
Unless your pond is heated, the pond bombs will be less effective in cold water temperatures. The nitrogen cycle will also be slower as the bacteria levels in the pond are very low at this time of year, therefore it will take longer for ammonia to convert to nitrite.
You will need to perform water changes to help manage the levels in your pond.
