Our aquaponics system has become more and more acidic over time, and we need to add a small amount of potassium bicarbonate most days to maintain the pH close to 7. We know our bore water (which is all we have, not being on the mains water system) has a pH of 6.4, but also feel the amount of gum leaves that land in the system contribute.

The piles of gum leaves that build up on the ground over the course of the week (between blowing, raking and removing), also provided snake hiding spots (see January), something we were keen to reduce. So, we decided to cover the whole system and aquaculture system in the swimming  pool with a patio roof, built by Great Aussie Patios, who were great from start to finish. Although the area was basically just a very large rectangle, there were many different heights and roof lines to link to and they did a great job.

Neat and tidy aquaponics area

It has been the best thing! We designed the roof to allow plenty of light to the grow beds and pots, but also to provide tin ‘walkways’ for blowing the leaves off. The roof has so successfully reduced the amount of leaves! The pool, grow beds and fish tank have remained clean, as has the ground- reducing our work load enormously.
