Spring!

The weather is warming up at last. The water temperature in the pool is now just above 18 degrees C. The frogs are calling again and we have seen a few water dragons. Dragon flies are starting to dart about.

However the pool does not look it's best! The water lilies and lotus have been dormant for winter and this leaves the filter exposed to view. A number of the plants are looking ragged. And the hair algae continues, although I don't think it is growing much now.

Just to get the algae into perspective though - I have spent a total of about 3 hours pulling the algae out of the pool with a rake. This is not too onerous. And the water remains crystal clear. We could certainly swim happily in it if it was warm enough. The photo shows the algae at it's worst, before I got to work with the rake.

It is interesting that the tadpoles that were there at the beginning of winter have not grown nor left the pool. They seem to be waiting for the warmer weather. This is a new phenomenon to me- tadpoles surviving through winter and delaying their development until
more favorable conditions occur.

The fish (red eyes) have bred and we have lots of juveniles. I am now looking into getting small red shrimp for the pool. These are native Australian shrimps and they are algae eaters. I think they will add to the biodiversity in the pool.

My underwater plants, mostly aquarium plants have had various success over the winter. I can see at least 5 species that have survived and a few of them have flourished and spread. I don't think that is too bad for plants that usually live in good lighting and shallow water. I will see how well I can propagate them in the warmer weather that is coming. I still plan on underwater gardening my pool.
