Tetra 77851 First Impressions

It's not heavy though.

I've been using these filters in my aquarium for years. Easy to use and a great price here at Amazon! The filters are expensive to replace and only so-so quality. Always needing to wash it out, with only 1 small catfish in the tank right now. I have used marine land bio-wheel pump and filters for the past 20 yrs. I've used it for years with great results. Okay, I don't own an aquarium- probably never will.

Tetra 77851 Final Thoughts

I'd give them 4.

The siphon works well and does what it should. I always deep clean my humidifier every week-week and half regardless. I've been using these filters in my aquarium for years. Don't claim to be an expert, but I've never heard of that. I've used it for years with great results. Yes I know, they aren't supposed to live that long and no I can't prove it. I used one gallon of reverse osmosis and the rest tap.
