MarineLand PA0373 First Impressions

"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.

"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.

API Final Thoughts

"00 product."

I have been using API on his suits for 3 weeks now and so far so good. I'm interested to see how long it works. Use a water conditioner that does not remove ammonia. I read the instructions, measured out the product, and added it to the tank. The chloramines contain a small amount of ammonia. I didn't purchase this for an aquarium. I hope it makes the swimsuit last longer.

API Final Thoughts

"This product is AMAZING!"

It is just as good when compared to other brands of conditioner. Just an idea incase someone doesn't have a spare dropper. During cycling you will be using often. Do not gravel vac or disturb the substrate. Pictures included to see the difference. It didn't kill the fish or cause any problems with the water so I stuck with it. I could see it working immediately which was pretty wild.

"Very little was eaten."

By the following morning, the water was clear of algae. I'm amazed, I'm really amazed that this product worked so well. I used to use AmQuel years ago and then spent years out of the aquarium hobby. If either or both ammonia and Nitrite are above 1ppm do not add ammonia. The aquasafe water conditioner is a fantastic de-chlorinator. In the last two months I have seen this product work its gold. The afternoon I received this product I added half a dose to each aquarium.

The equation is already done for you if you buy Dr. I love all of the API products, especially their easy to use test kits. The water we get here in SoCal is hard with chlorine in it. No observable signs of stress in the fish. When they disinfect a repair site, they are normally only using chlorine. The water we get here in SoCal is hard with chlorine in it.

"This a great deal."

The aquasafe water conditioner is a fantastic de-chlorinator. The top is a measuring tool as well which I was not expecting. You have to understand when to use this product, and what is is used for. 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. From their own colon or a hole in the ground. I was sort of nervous buy this product and trying it out.
