Ok, so, I went away for 5 days, came home and found about 1/4 inch of fish food laying on the substrate of my tanks, food growing mold everywhere and filters clogged. I guess the instructions left for my fish sitter were not followed. (too mad to even get into it). So, after driving 10 hours, I did about a 50% water change on all 3 tanks. I vacuumed the substrate as best I could. Fish are huge (bloated), but no deaths yet. Plants uprooted due to the deep cleaning, but will fix that tomorrow. Filters rinsed and now working. Plan to do another water change tomorrow. Any advice on anything else preventative I can do would really help. I will test the water in the morning. Should I continue with 50% change daily until I get the water clear and parameters normal? Any further advice would be appreciated.
