I live in a soft water area and eventually I am planning on setting up a 5g fluval spec v hopefully. As previously adviced on another thread a Betta is the only fish suitable for this tank so I am wondering if the water would be ok. I do have salt minerals to hand to make the water harder if needed as I have a 10g guppy tank too. The tank would be a fish in cycle. I have attached water peramters from my local water supplier. Any advice is appreciated, thank you.
