I want to build my first aquarium. I plan for it to be 200*60*60. But, as usual, money is tight, and I can't buy everything at once. So I decided to assemble it myself and start purchasing equipment as I can. While reading the forum, I realized that it's not worth starting without an osmosis system, so I ask for your advice on which reverse osmosis system is the most optimal in terms of price and quality.
