Damsel in distress....

Look at the sticky threads on cycling so you understand what is going on in your tank. The cloudiness is probably not a problem, pH is pretty much irrelevant right now, and the cycle is little more than snake oil--quit pouring it in. It is likely why the tank is cloudy and it is not helping in the development of the beneficial bacteria your tank needs. Pick up test kits for ammonia and nitrites--these are much more important right now that pH.

As long as there is no ammonia or nitrites, you don't need to do a water change. With 33 gallons, and 3 small bodied fish and one medium, you won't see a strong cycle--the fish don't produce a lot of waste for that volume of water. Ammonia should be detected in low titers within 4-5 days. This doesn't mean that you should add a bunch more fish though--you still want to give the bacteria time to develop.

Welcome aboard, by the way!

Cloudiness is usually one of two things--an algae bloom, or a bacterial cloom. The algae bloom will appear green against a white background, while a bacterial bloom will look whitish, or milky against a dark background. Both are caused by an abundance of some factor--foods in the water column, that we can't see, but provide a huge food source for little things-algae, bacteria, and a variety of micro fauna (little critters, like small bugs, worms, amoeba, etc).

Bacterial blooms are very common in new setups. The bacteria in question is probably not the beneficial bacteria that consume ammonia or nitrites, but a normal part of the aquarium system that is out of control right now. Not a big deal--the food source, whatever it is, will soon be consumed, and the bacteria will die back to a normal level. I would stop using the cycle--it is likely the food source for the bacteria.

Ammonia levels should be kept below 1.5 or less. You can establish a regular water change schedule now, even if ammonia/nitrites are not out of control--it's good to get into the habit of changing the water regularly. Then, as you monitor, if the levels jump, additional changes will help prevent serious problems for the fish. Once the tank is in balance, you won't see ammonia or nitrites, nor nitrates if you add plants. So, a regular schedule will ensure good maintenance for your tank in the long run.
