Hello guys

Tank size: 55 gal

I have a rena xp1 filer and the original one that came with my tank. The original looks like the penguin 330, but it doesnt have those bio-wheels and the intake is bigger

which one would be better to use???

Use them both, either one by itself is too small for a 55G IMO
On a 75G, people tend to run something like 2x AC 110 filters or similar. Aim for double the tank size compared to what the manufacturer states for a good general rule.
