Thanks everyone for your advices.

I’m trying to get a betta. I did some research and found that they need the exact opposite numbers I have. I don’t know how many guppies can fit in 6.6 gal.

The water I get from my tap has gh, kh and ph over 8. I want to drop it below 8 to medium. I ordered some catappa leaves to drop the number but I am worried due to the high kh. I don't have enough budget to get rodi water or distilled water. Can anyone give me tips on that? And also can you recommend me a good nano tank(6.6 gal) fish that can survive in these parameters?

Thanks for the advice @Theplatymaster
