Hello, I was reading up on the guide for High tech planted aquaria and there was a comment on removing or adding to the Juwel internal filter. The situation I have is that this Aquarium forms a divide in my terraced house. The downs stairs used to have two rooms but were knocked through in to one big room. The area where the wall used to be would be quite stong as the floor joists meets here. So you can see the back of the tank from one side of the room and therefore wanted to keep the ugly pipes etc minimal to one side of the aquarium (wall side). So I was thinking that i would have to remove the internal filter to be able to get the pipes through for an external. I would also probably need to have only one external because of minimalising the pipework. Does that sound ok? Next question, which external is better? I have seen the recommended Eheim 2080 and the XP5. The first has lower turnover (1700lph vs 2300), but the eheim has 12litres of media volume and the Fluval FX5 is 5.9. So... flow over media volume or the other way round? Hmmm.... nothings simple.
