If it because then running times

When it's up and running, then it's reasonably ...
But until you bring it with some sharp up and down movements for sucking, half the fish died of shock or has itself as green and blue annoyed that you would ultimately still throw in the corner.
Especially since I in half a cross member have in it in my aquarium (100 * 50 * 40) and one between times must change sides. If you then every time this has stress until the water is finally tightened times - no thanks. Vllt small simple basin. suitable. For large under any circumstances. Property me the JBL in-out order and hope, so better to drive now!
Unfortunately, I have the receipt no longer and it's been a while since I bought the product - otherwise I would give it back !!!!
