I am going to use it for my water changes on my 75g. Are all filter media standard for all water filters? or are there different sizes for different gal per day units. What sorts of upgrades can be made? would that just entail changing out the types of filters?
Yep, different brands of cartridges, media and membranes can be found for the different brands of units. The main reason I chose to go with a BRS unit is because they have a lot of options to pick and chose from. Anything from gauges measuring water pressure, to inline TDS meters, automatic shut off valves, flush kits, pumps to help boost efficiency etc. BRS gives you the option to pretty much build a unit specific to what ever you want. So you can start small and add on later if you ever feel like it's necessary.
Different situations might call for different methods of filtering. If your city happens to use chloramines (carbon does not remove) in the water then you may opt to run a chloramine removing cartridge. If you have well water with a lot of sediment you may opt to run multiple sediment cartridges, etc. Well water used to be considered good water to have. But now a days in a lot of places well water is becoming toxic from all of the oil drilling/fracking for natural gas that is about to spread like the plague all over this country for the next 100 years. Folks really should know what's in their water these days.
Personally, our city has pretty hard water and can be a touch high in phosphates. I'm going to run dual carbon and DI cartridges along with the sediment filter and membrane.
