API 33G First Impressions
Great price.
It doesn't just quickly slip on, and there's a reason for that. I decant this to a small 5 oz squeeze bottle and leave the rest in the fridge. I like to sit eye level with the tank substrate to see exactly what I am cleaning. You just give it some squeezes, and the outpouring begins and doesn't take forever. From their own colon or a hole in the ground. I bought this airline tubing to work with my air pump. I had a parasite problem, and had to heal my fishes scales and fins.

API 33G Final Thoughts
Contains 2 bottles.
Lastly, the hand pump primes very quickly and the water flow is wonderful. I am able to use each cartridge for about 5 weeks, before it needs to be replaced. 5 years now and I truly believe they help keep the humidifier and water cleaner. If you have a freshwater fish tank, I highly recommend this product. 5 gallon Top Fin Enchant Aquarium that I got from PetSmart. I have several similar products this one is my favorite. Works great to keep the purification process going in the humidifier.
