EcoBio-Block EBS-M Final Thoughts

"Never works."

I have a 5 gallon tank, so that number was waaaay too high for me. I have two 36 gallon tanks right now. It's water change day so I did this step first then started cleaning the tank. I'm interested to see how long it works. It has been 4 days and our beta is loving the clearer water. This worked really well for my tank. Use a water conditioner that does not remove ammonia.

"It was a viscous cycle."

I used to use AmQuel years ago and then spent years out of the aquarium hobby. Dunkin, my Betta doesn't seem to stress out over my adding this. I tried it without the water change and really didn't make a difference. Beats the heck out of those expensive suit cleaners. It is just as good when compared to other brands of conditioner. Thanks to the Amazon reviewer who mentioned this! It just hasn't helped with the tint.

"It was a viscous cycle."

You need to buy an eye dropper for this. You have to understand when to use this product, and what is is used for. Now our fish have grown and we've added live plants. From their own colon or a hole in the ground. However, be aware that the dosage starts at 20 gallons. I like that it's a large bottle with multiple uses, so that's nice. If you're serious about fish keeping, always quarantine and always use Stress Coat!

EcoBio-Block EMS-M2 Final Thoughts

"It will last a long time!"

However if you want a stress coat, this is perfect. My fish didn't appear negatively effected by it either. When they disinfect a repair site, they are normally only using chlorine. I do not use this as a product to treat my tap water. One planted that has algae problem so bad. It only requires 3 drops per gallon you add to your tank. By the following morning, the water was clear of algae.

No exaggeration-- literally cleared overnight. Use a water conditioner that does not remove ammonia. Beats the heck out of those expensive suit cleaners. I've always had a love for fish and had a few tanks when I was younger. When they disinfect a repair site, they are normally only using chlorine. I do not use this as a product to treat my tap water.
