Costs so far

Building these systems can be expensive but ours we have made out of generous donations from employers, the 1000 lt tanks were bulk caustic tanks which were very easy to clean out,as with the 200 litre drums which we cut in half with a jigsaw and then cleaned out the insides, the shade cloth was free from a previous job at a plastic recycling factory, and it is held up with poly pipe hoops which was also donated by a previous employer, mind you the star pickets which hold the poly pipe up now cost $9 each so there goes $90 for 10. We have spent approx $200 on plumbing pipe and fittings, after buying the wrong size pipe first up. Also $120 on pine poles and timber for the stand. As we have no power to this system we are going to use an inverter off a truck battery or maybe a deep cycle battery, with a solar panel to keep the battery full, we estimate a 80 watt panel should be able to run this system on and off 4 times per day. Price for solar panel is approx $600 so this will add a huge cost, but as the rest of the system didn't cost much its still not a bad price, we have estimated that it will come in around $1200. so it can actually be an expensive exercise. Anyhoo we will see what happens. I forgot about the price of an air pump which has 4 outlets 1 for each tank and airstones, it cost $80.
