ok so i went up to NY to visit family for a week, and i have two filters that filter at about 750 gph, i had my uncle in charge of my fish, i told him feed only a couple of pellets a day, (75 gallon tank), well he gave them the remaining food, used up 50% of the container. So when i came back i was furious my crystal clear water was smelly and cloudy. So i went to petsmart today and bought the aquarium vacuum, i got all the gunk off the bottom, but the water turned brown, so i did a 75% water change, (of course i used the conditioner+bioclear), the filters are working and the water has cleared up quite a bit, I bought 2 small pleco's (i have a pond outside and i live in florida for when they grow up), How can i get the water to clear up(will it ever be as crystal clear as it was?) and how can i keep it from stinking?
