1. Kordon Methylene Blue-General Disease Prevention Treatment for Aquarium

User Ratings: 76 3

Kordon MODEL-37344 First Impressions

"Of course."

The chloramines contain a small amount of ammonia. This water conditioner is a life saver! I have two goldfish and a Corydoras catfish. You have to understand when to use this product, and what is is used for. 4-5 squirts in a sink of water, soak my suit 10 min, wring out and hang to dry. This allows the conditioner time for its anti-heavy metal ingredients to work fully. Now our fish have grown and we've added live plants.

Kordon MODEL-37344 Final Thoughts

"This product is AMAZING!"

You have to understand when to use this product, and what is is used for. If either or both ammonia and Nitrite are above 1ppm do not add ammonia. He started making bubble nests again which ne never did when it was super cloudy. Boy, I thought I was having trouble with my filter. Don't know if that made a difference but it didn't hurt. The difference is that he was going twice his normal speed. It just hasn't helped with the tint.

"This a great deal."

However if you want a stress coat, this is perfect. The reviews on people fish dying really spooked me. I know you are going to want to add more chemicals, etc. I've used every product on the market and this is the most AMAZING MUST HAVE PRODUCT! I love all of the API products, especially their easy to use test kits. During cycling you will be using often. I have a 5 gallon tank, so that number was waaaay too high for me.

"Very little was eaten."

You need a source of ammonia to feed the bacteria which Dr. More doesn't hurt anything, but it's just wasted. I read the instructions, measured out the product, and added it to the tank.

The live plants even looked like I just bought them. I like that it's a large bottle with multiple uses, so that's nice. She seems ok with it she is behaving like herself. This is my absolute favorite conditioner I have used for all my aquatic creatures. My tap water is very heavy and this water conditioner does it's magic. I did water changes, but it didn't help.

"I am SO HAPPY!"

Fish are aerobic organisms that are susceptible to ROS. My water is crystal clear like the first day i filled it and i could be happier. Sure enough they are back to their healthy coloration and didn't end up dying on me. This is my go to water conditioner and stressed fish treatment. Use a heater and crank it to 82 degrees again without fish in the tank. It's water change day so I did this step first then started cleaning the tank. I have two 36 gallon tanks right now.

It gets rid of the chlorine in tap water. I was sort of nervous buy this product and trying it out. It took a couple of days to clear but it works.

My water is crystal clear like the first day i filled it and i could be happier. 1st day, I put product in tank with Fluval Biological Cleaner for Aquariums also.

I have used this consistently since cycling my small sized fresh-water tank. I read another review for this product saying they were using API for this purpose.

"It was a viscous cycle."

I have been using API on his suits for 3 weeks now and so far so good. It's a must for anyone who loves Goldfish. Use a water conditioner that does not remove ammonia. This product is exactly what it says it is. Pictures included to see the difference. I decided to pick it up once again and struggled mightily my first few months. Fish seem healthy and active during use.
