The Current Bush Fires and the Impact they have on your Ponds

Due to the current bush fires affecting so many people across Australia (and in particular NSW) we wanted to first and foremost say that our hearts are with all those whom have suffered loss through these tragic fires. Also, we wanted to discuss the impact that these fires have on your beloved pond.

The constant ash and smoke that has been raining down for the past few weeks will affect your ponds water chemistry – and not in a good way.

The ash is full of phosphate which contributes to poor water quality and excessive algae – in particular, string algae.  Too much phosphate can also be linked to fish health issues so keeping it under control is beneficial to all involved.

There are a few simple solutions here and the first is a partial water change “dilution is the solution to pollution”. (Please note that if you are on tank water you must be aware that your tanks are now contaminated and full of phosphate (This will be fine for the garden, just not for the pond), So a water change if you are on tank water might do more harm than good until you can clean the tanks out).

 If water changes aren’t possible we have a few other methods. For those of you that currently use our “maintain” liquid – in either the pump pack or auto doser, you should double your dose until further notice. This product has a phosphate binder in it.

There are also commercial liquid and powdered phosphate binders derived from a clay particle. These would be your best bet if you have a very large pond.

Each situation and every pond is different, so I would encourage you to reach out to us and we can make the best recommendation for your situation. Contact us today.

Unfortunately too much smoke can have a similar effect on fish respiration as it can for us, while this is unlikely to affect most people in the levels we are seeing, it is worth noting that increasing the surface agitation to release some of the additional C02 would definitely be beneficial. One of the best ways to do this is with one of our aerators. See below our aerator options.

If you have any further questions concerning your pond and its inhabitants, need to discuss what to to do during this bush fire season, or questions regarding air diffusers and/or aerators, please don’t hesitate to get in contact and we would be happy to answer any questions.
