Changing Substrate

[karin]

A note on the gravel you selected. Be Aware. I have something similar in my 29 gallon and the gravel has sharp edges. I suspect it of killing 4 bristlenose plecos. I will not be getting any soft belly fish (plecos or corys) until I change it to sand or smooth round gravel. That said, mine might have sharper edges than the one in the picture. Personally, I would look for something different so you don't run into problems or limitations in the future.

Might go for this to replace the undergravel filter:

What you think?

On the right track, but I'd find a Fluval 4+, much bigger with more filter media and a higher water turnover.

But how big? My tank is 65l.

You can never over filter, and you can always turn the flow of the bigger filter down, you can't get any more out of a smaller filter once it's running at max. You'll also go longer between needing to clean the filter out as there's more filter media for the water to go through.

Here's a link to the Hagen site with specs of the 4+, and you should be able to find the 2+ easily enough. I'm currently using a 4+ in my 60l tank with about 10 galaxy rasboras and a couple of cory's and the water is absolutely spotless. Like I say you can never over filter your tank.
