"I was very surprised."

If you're treating injured fins or introducing new fish, this is for you. When they disinfect a repair site, they are normally only using chlorine. I've using this for my betta for several years with every water change. However if you want a stress coat, this is perfect. I hope I made the right decision, Betty is our family pet and is really loved! I was sort of nervous buy this product and trying it out. Don't know if that made a difference but it didn't hurt.

Penn-Plax PBC3M Final Thoughts

"It will last a long time!"

Fish seem healthy and active during use. My tap water is very heavy and this water conditioner does it's magic. However if you want a stress coat, this is perfect. Sure enough they are back to their healthy coloration and didn't end up dying on me. I use in a freshwater aquarium and works well. Crystal clear after changing water and adding this to my 2. By the following morning, the water was clear of algae.

"I LOVE this product."

By the following morning, the water was clear of algae. Very good product for an unbelievable price. It took a couple of days to clear but it works. The top is a measuring tool as well which I was not expecting. If you have a freshwater fish tank, I highly recommend this product. In the morning I awoke with my fish at the bottom barely able to move. I love all of the API products, especially their easy to use test kits.

  • Seachem Flourish Excel Bioavailable Carbon
  • CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon.
  • IRON PRODUCTION: Flourish Excel also possesses iron reducing properties, thus promoting the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).
  • PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds, and introduce the already finished, structurally similar compounds.
  • TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (5 mL) for every 40 L (10 US gallons). Thereafter, use 1 capful for every 200 L (50 US gallons) daily or every other day. For smaller dosing please note that each cap thread is approximately 1 mL.
  • SAFETY: Flourish Excel is completely safe for fish, however if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.

"Very little was eaten."

Beats the heck out of those expensive suit cleaners. My water is crystal clear again, and it smells like a healthy fish tank again. Fish would die occassionally every few weeks or so. It is just as good when compared to other brands of conditioner. I did water changes, but it didn't help. Now our fish have grown and we've added live plants. This is only temporary till I get a spare dropper.

More doesn't hurt anything, but it's just wasted. This is definitely worth trying if you have cloudy water. If you're serious about fish keeping, always quarantine and always use Stress Coat! UV light works on it but not much else.

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.

"This product is AMAZING!"

This is the 5th since I put in the product and my tank is crystal clear. I'll continue to use this product, especially after a good tank cleaning. I even poured in extra to help with the healing. Do not clean the filters, do not change the filters. I've had my fishy for 5 years now and I would say it's ALL because of Fluval. More doesn't hurt anything, but it's just wasted. If you have new tank syndrome then this is the stuff.

"It's CLEAR!"

1st day, I put product in tank with Fluval Biological Cleaner for Aquariums also. It's water change day so I did this step first then started cleaning the tank. This will give you how many drops is required per gallon. The water we get here in SoCal is hard with chlorine in it. Fish would die occassionally every few weeks or so. Use a heater and crank it to 82 degrees again without fish in the tank. I've always had a love for fish and had a few tanks when I was younger.
