Portable mixing station for under 100

[BionicReef73]

Hello everyone,
I would like to share my DIY portable mixing station for those who are handy and have limited space.
Breakdown of Costs in CAD.
* 15 gallon barrel = 20
* cheap pump = 15
* fittings, hose , shut-off valves = 42
* 100 watt heater from amazon = 20
* small temp prob that came with something I had bought think they're about 10 bucks on amazon. (optional)
* sediment filter = 35 on amazon. (Optional)
* colapsable dolly = 40 from Home Depot ( Optional) could always use a small cart of some type.
I like to consider myself kinda hand and am always looking to find a way to do things cheaper and hey maybe even better than whats available. This total build cost me 175 after taxes and fun stuff......lol. But could be built for just under 100 or even less if you can get the supplies cheaper. I have included pics of my tank and te portable mixing station.

Strap on a 3 stage RODI unit above the tank onto the dolly and it's good to go . Neat design.

I have a 30 gallon res in my spare room, that I use for quarentine and water make-up. I have the RO system piped in there. the portable mixing station so I could make water changes in my main system easier than just a few brute trash cans. I will open up the unit and take some pictures of the internal working of the system. But thanks.
