"I LOVE PRISTINE!"

Fish possess an antioxidant defense system to reduce the negative effects of ROS. This is my absolute favorite conditioner I have used for all my aquatic creatures. My water is crystal clear like the first day i filled it and i could be happier. However, be aware that the dosage starts at 20 gallons. 4-5 squirts in a sink of water, soak my suit 10 min, wring out and hang to dry. We use it when we clean& change out water. I didn't purchase this for an aquarium.

"This product is amazing."

Fish possess an antioxidant defense system to reduce the negative effects of ROS. Easy to dispense the product without mess and easy to use per instructions. I decant this to a small 5 oz squeeze bottle and leave the rest in the fridge. This only applies to the 1st application. DON'T just wait everything will be fine. I have been using API on his suits for 3 weeks now and so far so good. Crystal clear after changing water and adding this to my 2.

MarineLand First Impressions

"A MUST BUY!"

But the septic tank bacteria did nothing. The reviews on people fish dying really spooked me. If you have a freshwater fish tank, I highly recommend this product. Pictures included to see the difference. It's water change day so I did this step first then started cleaning the tank. Dunkin, my Betta doesn't seem to stress out over my adding this. The afternoon I received this product I added half a dose to each aquarium.

"He was fine in no time."

Makes me want to get more aquarium's, lol. Yes I know, they aren't supposed to live that long and no I can't prove it. I know you are going to want to add more chemicals, etc. Boy, I thought I was having trouble with my filter. I have been battling cloudy water in our small aquarium for two months. By the following morning, the water was clear of algae. DON'T just wait everything will be fine.

"Thank you!"

Easy to dispense the product without mess and easy to use per instructions. She seems ok with it she is behaving like herself. I'll continue to use this product, especially after a good tank cleaning. Use a water conditioner that does not remove ammonia. My fish didn't appear negatively effected by it either. 1st day, I put product in tank with Fluval Biological Cleaner for Aquariums also. I wanted to see if it would take the chlorine out of my swimsuit.

"Pet Smart knows nothing."

You need to buy an eye dropper for this. She seems ok with it she is behaving like herself. I have two 36 gallon tanks right now. I decided to pick it up once again and struggled mightily my first few months. I know you are going to want to add more chemicals, etc. No exaggeration-- literally cleared overnight. The equation is already done for you if you buy Dr.

Do not gravel vac or disturb the substrate. It has been 4 days and our beta is loving the clearer water. I'm interested to see how long it works. The aquasafe water conditioner is a fantastic de-chlorinator. I'm sold on this, I've tried SO MANY and wow. I have two 36 gallon tanks right now. Ever since I made this purchase, my fish are not dying at all.

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.

It just hasn't helped with the tint. I've using this for my betta for several years with every water change. He started making bubble nests again which ne never did when it was super cloudy. If you have new tank syndrome then this is the stuff. Crystal clear after changing water and adding this to my 2. This will give you how many drops is required per gallon.

"A MUST BUY!"

I have used this consistently since cycling my small sized fresh-water tank. This came just in time for my water change day! But the septic tank bacteria did nothing. Ever since I made this purchase, my fish are not dying at all. I've always had a love for fish and had a few tanks when I was younger. It is much safer to simply to add 3 drops per gallon. Beats the heck out of those expensive suit cleaners.

"No argument from me."

You need a source of ammonia to feed the bacteria which Dr. This product is exactly what it says it is. This is definitely worth trying if you have cloudy water. Crystal clear after changing water and adding this to my 2. I've used API water conditioner before and it works well. It just hasn't helped with the tint.

I love it when a product does what its supposed to.

I have a Fluval tank and only use their chemicals. I had a parasite problem, and had to heal my fishes scales and fins. This is my go to water conditioner and stressed fish treatment. I read the reviews, and decided to give this a try. The bottle will last me years as it is huge! I swim 5x week and usually my suits last about 2 months. This is definitely worth trying if you have cloudy water.

I use mine for my beta fish in a 2 gallon tank and need less than a half a cap full. It didn't kill the fish or cause any problems with the water so I stuck with it. The live plants even looked like I just bought them. I have had aquariums for 40 years and have always used their product Cycle. If either or both ammonia and Nitrite are above 1ppm do not add ammonia. It's a must for anyone who loves Goldfish. I'm sold on this, I've tried SO MANY and wow.
