We have a brand new 30 gallon tank, had perfect water readings as of yesterday. Two Mollies and an ADF from our old 10 gallon, and a new Molly and a new Solar Flare that we added yesterday. The tank has our old filter feeding BB into the new one. We have an underground filter system set on low, and a Aqueon 50 filter hanging on the back. One moss ball and one floating fern (for fry). Temp is 80. Okay, so this morning my four year old dropped several handfuls of FD worms into the tank. I'm not sure how long before I came out and saw. I immediately stopped all the filters and scooped out every bit I could. Then tapped it all off the filter cartridges and started everything back up. Water is now cloudy and tons of is on the substrate. I have a vacuum...my question is if I should vacuum and replace the water or just wait for the tank to filter itself? The frog and solar flare seem to enjoy the snacks they are finding...but the water is so cloudy.
