I HAVE A PROBLEM WITH MY ROSY REDS DYING. I'M TRYING TO KEEP THEM FOR BAIT. THIS IS MY SECOND BATCH. THIS TIME I BOUGHT THE LARGER MINNOWS 2"-3". I'M USING A CHEST FREEZER WHICH HOLDS ABOUT 35 GALLONS. I HAVE AN EXTERIOR 3 STAGE FILTER. I ALSO HAVE AN 18" BUBBLE BAR. I USED R/O WATER THIS TIME BECAUSE OUR WATER HERE IS VERY HARD. I TREATED THIS BATCH FOR PARASITES AS SOON AS THEY STARTED DYING. I STARTED WITH 250 FISH IN THE FREEZER/HOLDING TANK. I KEEP THE WATER TEMPERATURE BETWEEN 70 F/ 75F. I FEED THEM SPIRULINA FLAKES TWICE A DAY. I FEED THEM WHAT THEY CAN EAT IN 3-5 MINUTES. MY TANK HAS NO GRAVEL. IT IS A BARE ALUMINUM BOX. ANY IDEAS WHAT I CAN DO TO STOP THESE FISH FROM DYING?

Welcome to the forum. Sorry about your rosy reds. Most rosy reds that you buy are already very ill. That's the first problem. Then, you are putting way too many together, about ten times what I'd recommend if you had a mature filter. Have you tested the ammonia and nitrite levels? I would make a guess that they were very high. You need a seeded filter with good bacteria. Frequent water changes can help with the waste as well.

I'm assuming you are keeping them as bait since you have so many?

You can start with RO water if you need to do so but you must add some minerals and salts back. Fish cannot survive in straight RO water. You can add small amounts of a good marine saltwater mix, not to make the water very salty but to return some minerals. It won't take much, maybe a tablespoon per five gallons or so.

Another problem is the aluminum. If the pH is acidic, the aluminum is also toxic. Here's someone's paper on that: http://www.academia.edu/2851808/Effects ... dic_waters

Also, please don't post in all capital letters. Thanks and good luck!
