@@Manus_0813 i say the best and cheapest is anything that says “reverse osmosis”. For the longest time (when i had my 20gallon), i do 10% water change 1-2x a month, i just buy two-1gallon water from the store cost me like $2-3 bux each time.
@@Manus_0813 now that i have a 75gallon, i just use tap water. Been running it for 2yrs now just softies and hardy fishes. Inspired by the youtuber “BTUFF”
@@Francis.Riverscan you give some advice how to start start water aquarium with tap water , I cycles my tank for 6 weeks with grocery water and failed . Now I’m very frustrated and everyone i ask help telling me to buy RODi systems . 😢
@@TheBrelson how did it fail.? Grocery water is fine(as long as its RO to be safe). Check the tap water in your area and experiment if its safe to use. Use dechlorinator is you need to (i dont) Also don’t put corals or fish that are not hardy. I only put soft corals and just one LPS(duncan). I have a video if you wanna see my setup. I have a 75 just running on HOB. (I like to keep it lazy & cheap)
