Oct01Miguel Rodrigues I plan on having snhmteiog like that but not so advanced and not so expensive also, just to control: 1. water temperature, 2. pH and ammonia and 3. having an electric backup as well as having every device running 24/7 on solar panels.1. Water TemperatureKnowing that i need the water at 20baC i will have a simple aquarium heater ($10 to $20) that will turn on at 19baC and stop at 20baC, wen the water goes to more that 20baC i plan on having a simple setup with an arduino ($1 to $20), a temperature probe ($?) and 2 fans ($10) that i will configure to turn on the fans at 21baC and stop at 20baC.2. pH and AmmoniaI want to know (constantly) the pH and ammonia on the water at a low cost, for that i found a device that give me constant information about this both stats on the water. Just search ebay with the words pH alert ($10). 3. Electric BackupI want to use solar panels to power my pumps 24/7 and use the grid only for backup. For that i will use some car batteries, some solar panels, a solar controller, an inverter and to switch automatically from batteries to the grid ill use a relay. Prices for those will depend on what energy you need and if you can make or not your own solar panels, if you can you know it will be much cheaper.The fish feeder and the time switch for the pump are also cheap, about $10 each.All of these will need some testing but i think will solve most of those problems at a LOW COST and with SIMPLE KNOWLEDGE. The prices are always for ebay items (excluding shipping) just because its the place were i can find the best prices in my case.Best Regards and be Creative
