Hi kazman,
The cloudiness could be a couple of things, but it is very normal yes
Have a read through this in terms of cycling:
The (almost) Complete Guide and FAQ to Fishless Cycling - Aquarium Advice
A couple of questions, what is your substrate (the material you've used for the bottom of the tank, most people use sand of gravel)? And did you rinse it before putting it in?
And also what is your tap water's pH? If you tap water's pH is between 6 and 8 naturally then there isn't really a great need to add pH 'changers' in. Most fish you choose stock will get used to your tap water's conditions, provided you use a suitable dechlorinator (most like use Seachem's "Prime", but there's many different types out there) and acclimate them properly when introducing them to your aquarium.
Do you have a test kit for ammonia, nitrite and nitrate?
What equipment are you using? (heater, filter, lights etc)?
Every tank is different in terms of how long it takes to cycle. Some go by quickly, others take months. If start zyme is the product you used, I think that's a 'bacteria in a bottle' product, and should help speed up your cycle if it does what it claims. People tend to have mixed success with such products.
10 gallons limits your stocking choices, but there are still so many choices that makes it hard to offer suggestions. A honey gourami or sparkling gourami are good choices as centrepiece fish, or
maybe a betta if you choose the right tankmates and the betta you choose has an easygoing nature. This could be with some of the smaller corydoras species (such as pygmy), or kuhli loaches for a catfish/bottom feeder type of fish. Then a small school, such as neon tetras. Just be sure the fish you choose stay small (within a few inches) and are not active (like zebra danios).
Other fish you could consider are killifish, smaller tetras and rasboras, nano fish, threadfin rainbowfish, smaller male livebearers (guppies or endlers)
There is a site called
AqAdvisor that is very handy in figuring out how many and what kind of fish you can have. It's not 100% accurate but it's better than others, you should just want to check back here with your stocking plans though.
I'd suggest to stay away from fish such as angelfish, goldfish, oscars, other 'cichlids' (even if they do look good) and plecos, even the smaller varieties. These are often put into tanks that are too small as people have misconceptions about what these fish can live in, or pet store employees misinform customers.
The best advice is to research every kind of fish that you plan to get thoroughly, and don't rely on 'guidelines' - for example the 1 inch per gallon guideline isn't overly accurate. Don't always trust what the salesperson at your local pet store tells you. Any questions can often be better answered by us here on the forum and that'll help you have success with keeping your aquarium
Good luck!
