Bought a new love fish 27L tank yesterday, set it up washed all gravely with cold water thoroughly, boiled all the rocks and drift wood and it has 3 real plant in, I added de-clorinator which supposedly had bacteria in it for cycling last night and all was well woken up this morning and it wasn't as clear didn't think anything of it, and went to the shop to by proper a heater and some proper cycling bacteria, and a few hours later it's getting cloudier and cloudier is this due to a bacteria bloom or should I be concerned, it's for a betta which I'm due to get in 2/3 weeks!
