Hi, I would like to change from an internal filter to an external filter. The tank currently has 240 liters, but will be replaced by a 450 liter tank around the middle of next year. Which filter do you recommend?
I've read a bit about Eheim and Oase, maybe you can see some differences etc.?

Loading...Hi Several of my male guppies have died because they could no longer swim upright. I'm a little confused because at first I thought it was fin clamping, but it has nothing to do with the fins. In the end, they lie on the ground, just breathing. Otherwise, they don't move. What could that be?
What are these brown spots on my aquarium plant?
Good day, I discovered this jellyfish on the beach just outside Malaga. I accidentally stepped on its tentacles and now I don't know if it's poisonous. Can anyone help me? Greetings:)
I used regular salt for my brine shrimp, even though everyone said it doesn't work. One day later, they hatched. Can anyone tell me why they still hatch?
Hello I have an aquarium in my bedroom and have been unsure for some time whether I can turn off the light at night… – I mean, it's dark in nature at night too, so that should work, right?😅
I have two goldfish and would like to give them some crumbs from my cake because I turned 22 yesterday. I've already given them some cookie crumbs and wanted to give them a little treat, but they were still fine afterward. Is that okay, or should I just leave it?
Does it have to be external filters? Also have 450 liters and stayed at internalfilter.I build my filter but also myself. Eheim is a good manufacturer. External filter has the part that it pumps empty in case of error.
