Easiest way to keep the water quality up is with a baster. Just suck up feeding debris 2-3 times a day and it’ll never rot in there. Cloudy water is a shortcut to losing another batch of fry. Fry can be sensitive to big water changes too. Especially when they come with a dramatic chemistry or temperature change- which you’re going to have a big chemistry change going from cloudy to tap water (mostly it’ll just be going from toxic water to healthy water so do it)
More frequent water changes are going to be your friend. In 2 weeks the fry will have more than doubled the bio load- so your already behind the 8 ball
