Okay so here it is click on the photo to make it bigger
It is in the left bottom corner of the photo
A view from the top shows all the fittings
The connectors are to send water in and out of the unit
The snap on garden fittings mean no leaks and the pipe does not fall out the Bucket
The temp gauge of the water in the unit
Switch for the light so you can see the highlighted white marks 10lt per from mark to mark
Switch for the water pump that pumps 10lt per min to a height of 25 meters if needed
The access to add meds holds a syringe in the fitting and water clarifier
The perspex window to see into the container
A view inside the water drum is the inlet pipe and outlet pipe
The heater to warm the water
The air stone
The sensor for the temp gauge
The water pump that uses 12volt attached to a adaptor and does 10lt per min up to 25 meters high
The blue LEDS attached to the under side of the lid make white glow bright blue and the white marks are every 10lt the square is polystyrene and floats attached to a guide that is attached to the bottom and the lid to keep it from floating away from the markers but allows it to go up and down.
I have used snap on garden fittings on all connections so removing and joining pipes is easy
I fill the unit and add the water clarifier to get rid of unwanted chlorine ect and leave it for a week the heater heats it the air bubbles stir it.
and the temp gauge lets me know the water is the right temp to add when ready I clip on the hose put the one end in the tank and flick the switch.
To drain the fish tanks I siphon the water using the same pipe I use to fill the water storage unit straight into the toilet before adding the new fresh water back into the drum for the next week
I have now finished the unit and the perspex window in in the lid
The temp guide said 38 as I put in hot water the first time and pumped it out to clean the pump and container of anything that should not be in it
