Hi all
I got a two questions for you. I have discovered near the family house in the countryside a small building that collects rainwater. I use tapwater for my largest tank but I am trying a mix of RO+(hard)tapwater in a small one. The 50% weekly WC is 7 liters, so I use just 3.5 liters of RO which I have to buy (0.1€/liter).
This new finding opens the possibility of collecting once a month all the amount of water I need (at least during some months or after rainfall). Luckily we have a GH test kit (forgotten by the washing machine technician) and what surprises me is that it gives a result of 4dGH. Do you think it is rainwater with this value? I am not sure if it has been harden somehow in the concrete water tank (maybe limestone sand/rocks used). The tapwater (from the limestone aquifer) gives 14 dGH. I have my KH test at home. The RO water I buy at the LFS gives obviously 0dKH. Would this result be more important than GH?
The other question. The only thing I have for bringing the water home are plastic cans that were used for doing DIY ferts (comfrey+water) and mixing a mild organic fert (based on beetroot and manure with a nitrogen richness of 3%)... It has been dry for months. I can buy new ones these days but I have a few of them and I would prefer to recycle them. My guess is that a light wash with water and it will be ready to use, what do you think?
