API 720D First Impressions

In one day crystal clear.

The bacteria eats the nitrates in the water to help keep it clean. I DONT KNOW WHY MANY THINK THIS IS A NOISY FILTER. This filter has is a very simple and efficient design. Overall I would recommend this item. Basically, make sure everything that is suppose to spin, does so smoothly. You CAN rinse the old ones in an emergency. I was worried that it might be too much for my aquarium or that it would be loud.

API 720D Final Thoughts

Like brand new.

The filter stopped working all of a sudden. I plan to cycle this new AC 50 on a separate tank and then xfer it to the 20 gallon. I attempted to clean and lube the impeller, but to no avail. Overall, I like the 350's slim back design, and be able to add up to 4 cartridges. It wasn't producing much surface agitation. It wasn't producing much surface agitation. So, easy is good, both for us and our fish.
