Years ago, when I kept fish, I used under gravel filters, because that's what came in the aquarium kits that I bought. I remember them being easy to use, and mostly maintenance free.
Now, I have got back into fish keeping, and I use either internal filters or HOB
, again because that is what came with the tanks.
What's the deal? Why the big switch in the industry.
Who here still uses under gravel, and how do you feel about them.
I ask because I already had a filter break, and had to replace it. I was thinking that if it happens again I might go back to under gravel.
I'd like to hears pros and cons.
Thanks in advance for your opinions!
