Hello, This is the second time that I have had problems with this tank. About 2 months ago I lost an 18" 7 y.o Marble Sailfin Pleco, a 7" 7 y.o spotted "pim" pictus cat, a record size 7" 7y.o Rare Jet Black Red tail Shark, and a 7 y.o Tiger barb that was as round as a 14 oz jar top due to an aggressive bacteria called costia that was introduced into my tank when I 6 Black Skirts, 5 Giant Danios, and 2 new Tiger Barbs into my tank. It was so agressive that it set a cycle that I couldn't stop. I asked The "Aquatic Specialist" at Petco what to do. She asked what I had for fish I told her. She advised me to use Aquarium Salt and API Ich treatment in my tank. Knowing I had Scaleless fish. I was not aware that I could not use either of these substances at the time either. I guess you could say I was ignorant of the contents of the substances. Slowely exactly 2 weeks to the day of adding the new fish My shark was covered with the white spots you could barely tell he was Black. I 1st found my pim dead I thought it was stress then that night the Shark had white spots. The next day I was observing the new fish as they showed no signs of sickness and I watched 3 swiming and all of a sudden they just dropped to the bottom of my tank dead. I brought the 3 fish back to Petco along with a water samole and my numbers were zero across the board. Once again Knowing what I had in my tank for fish they told me to Coppersafe (a big nono for Plecos of any kind and Sharks) and then the next day my Extremly large Barb died. Then that day I went back to Petco and Informed them if my Pleco died there would be a law suit. The next Morning My Shark was dead and then that night my Pleco died. To make this long story short over $5000.00 worth of damage done between fish, tank orniments and filter media. Not including the cost of tank and Canister filter system. My tank has been set up once again for 5 weeks with fish and it has been running a total of 9 weeks. Now once again I have now lost 4 Albino Rainbow Sharks 1 female gold gourami, 2 rainbow Sharks and one black red tail shark. My new Marble sailfin started showing signs of white spots and so did my 2 remaining sharks so I put them in a hospital tank. I have 6 Tiger barbs, and 2 gouramis still in the large tank and they seem ok except 1 barb is swimming funny kind of like he has a swim bladder issue but that is it. What should I do? I have called marine specialists and they don't know what is going on. I cannot do salt bats to the Pleco. Any amount of salt no matter how small of a dose it is, is toxic to them and there is no safe ich treatment if this is what is going on. Nor is there any bacteria treatment safe for plecos either. What can I use and please don't tell my liquid Garlic or salt.
