Cloudy water / pregnant platy?

[wertyu5555]

I have an aquarium of 135 litres capacity. I first filled it with water 3 weeks ago
and i did a fishless cycle for two weeks. the filter is biological. A week ago i put 12 cardinal tetras two angelfish, 4 platies, and an algea eater. The problem is that since day 1 the water of the aquarium has been very cloudy and has remained that way ever since. Of course i put inside STRESS COAT and STRESS ZYME but due to an error made by the LFS i put smaller doses that necessary. and another problem is that a day after i first filled it i had to empty it because the aquarium had to be moved. then i filled it again putting again the two liquids mentioned above. what can i do about the cloudy water? i also observe that a lot of the fish excrement is flowing in the water.
Another question: one of my platies started hiding inside a ship wreckage and is only coming out to feed. I m not sure if its a female, but does that mean its pregnant and is going to give birth soon?

When you did the fishless cycle was it finished in 2 weeks? My water was cloudy also. It may have been a bacteria bloom or something. Can you turn up your filter at all? If you can try a couple 20% water changes, ever so often. If not working just try and wait it out same thing happend to me. Did a little water chance and waited a few days and now its just about perfect.
