Rogue Scales Posted June 27, 2021 Share Posted June 27, 2021 I have one 20 gallon tank in my living room that is consistently unsuccessful. It has a heater set to 78 degrees, a sponge filter and hang on back with sponge instead of carbon filter. This tank has been set up for a year with consistent normal parameters. My other tanks in my bedroom have not had the same problems. Here’s what I mean by unsuccessful. I have had white clouds, cpds, bettas, platys, snails, plants including moss, octopus and crypts in the tank and rotated as I noticed them not thriving. The fish spent most of the time hiding and while they ate, I noticed they were getting skinny. I had groups of 8 (except the betta). This was particularly obvious with the cpds. The snails would die off within a few weeks of putting them in. The plants would be growing and green for about 2 months then suddenly die back completely or to less than half the leaves they had. I haven’t had an algae problem at all in this tank. I have done up to 50% weekly water changes when I noticed a problem. The fish were quarantined prior to going into the tank and again before moving to a new tank when I noticed they were struggling. Plants have gotten easy green and root tabs with no improvement. At this point I feel like I should completely tear down the tank, clean everything and restart. Does anyone have any ideas what could be the cause? Better recommendations on what to do other than tear down? Link to comment Share on other sites More sharing options...
