![]() I vouch for the Hydor Koralias, too. I've had lots of problems with the Tunze Nanostreams, and none with the Koralia that I picked up a few months ago.
The Vortechs are so expensive, and it's fairly limited. I don't think heat would be much of an issue with the Koralias, because they operate on such a low wattage, respectively. The flow you could achieve with three or four Koralia 4's would be much better, IMO. |
