KittenFishMom Posted March 21 Share Posted March 21 (edited) The sponge filters and HOB sponges are filling with muddy mulm much faster than before. I'm trying not to clean more than half in a tank in 24 hours, but it is amazing how cloudy the water is getting and how much gunk is in each filter I clean. I'm starting to think it is the cory fry and youth digging in the sand, stirring everything up looking for food. I have ACO sponge filters, and HOB filters with pre-filters and the media replaced with more sponges plus nitrogen sponges. Those tanks are Walstad tanks, meaning there is potting soil under a sand cap. You can not gravel vacuum the bottom. I did a 20 gallon change on the 55 yesterday and it looks so murky today. I have cleaned all the mechanical filter spaced an hour or so apart and have Stability, Prime, and Turbo Start 700 on hand, in case I lose the cycle. Hopefully the breeder will come this weekend and take more fry and adults. I have to catch them before she gets here. I think I have moved almost all the fry out of the shrimp tank and into the 15 gallon tank. The 55 gallon tank is very heavily planted and full of fry and adults. I'm afraid I will need to set up another tank to hold those fry so I can start catching them a few days ahead of time. I am thinking I may try setting up a temporary 15 gallon bare bottom tank with fake plants to put the adults and fry in over several days before the breeder comes for them. Then I can remove everything when the time comes to catch the fish. I have never gotten a bare bottom tank to cycle. I really worry about cory toxins in the water when I am netting them. I have had some luck trapping fry in a water bottle trap, but I don't take my eyes off it once I put it in the tank. I bait it with frozen hatched brine shrimp. and pull the trap as soon as one fish panics. All thoughts and advice on any of this is very welcome. Would love to hear from @Streetwise or @lefty o or @CorydorasEthan or @nabokovfan87 or @TeeJay or @Guppysnail or @Cinnebuns or @Chick-In-Of-TheSea or anyone with experience with Walstad tanks, bare bottom tank or Corys.
