As I wrote in one of the earlier topics, I am planning to setup an 600Ltr. (160gal.) tank for Centrals. But Which one of them will go there, it's a big question. It all depends what I'll can get thanks to my friends. So, I'm going to filter the tank using a "background" filter, similar to Lee use, slightly modified. You can see my idea here:
Inner dimensions of the filter will be about 70cm long, and 12cm width (height of the background, of course).
My main question is, how strong pump I should use. On Polish market there's not much to choose from, there are only quite weak, about 1000Ltr./hour, or much stronger, about 2000L/hour, and I have no idea, which would be the best.
I found this one:http://new.aquaszut.pl/index.php?option ... &Itemid=85
It is from reliable polish producer, with quite reasonable price (that is about $60), but I'm affraid it's too strong. In comparison Willem uses 3600L/hour pumps in 4 times bigger tank! I have read an old article of George Reclos and others about filtering in cichlid tank, (smaller tanks=more efficient pumps) so this is why I have doubts.
Thanks in advance.
