Does boiling affect the hardness of water?

I've been using RO water for my tetra tank and it's worked out great. It's a better option than distilled water, in my experience. You can pick some up and use it for your water changes – it's a good way to go.

Just read the description and it's indeed just the cartridge. Guess I'm a bit clumsy for not checking that first.

I buy mine from a local soft water dealer - I'm not really familiar with the equipment, just the end result. There are some folks on this forum who have their own RO systems, but I looked into getting one and it's just not in the budget - over $1,300, and the wife isn't exactly thrilled about dropping that kind of cash on my fish.

No, I just have to slip in through a side entrance at their place of business to fill up my jugs with the good stuff – RO water.

I source my RO water from a local soft water dealer, but I've never had to purchase a system like the one you're looking at. There are some members here who have their own RO setups, and I've considered it too - however, the cost was a bit steep for me, at over $1,300. My wife wasn't too keen on spending that kind of money on my fish, understandably.

I was initially looking at the whole house setup, but this option seems more suitable for my needs, thanks for the suggestion. They also recommended a water softener, but I'm not sure if that's necessary.

Found this, is it alright? My betta's tank is about 30L, so I'm thinking it'll be like 70-5% of water to be removed from his tank. Anywho, I'll get some Indian almond leaves to be on the safe side and just live with the tannins.

I'd suggest checking out local fish shops for RO water, it might be a more cost-effective option than ordering online. A thing to keep in mind, once you start using RO or deionised water, you can't just do a water change with tap water anymore. In case of an emergency, you'll want to have some on hand.
