Hello everyone! I just ordered a Hydor Koralia Nano 425 from Amazon (only $11, new condition!). I should have it in about a week. I've read some articles and had discussions about the importance of having flow in the aquarium for plants. One of the things that it apparently helps with is keeping gunk from settling on the leaves of plants. That's definitely something I've had an issue with. My filter, an AquaClear 70, definitely pulls a lot of water for my 29 gallon - but even with that, a good portion of the aquarium doesn't seem to have much moving water at all. That being said, what's the best way to aim/position the Hydor pump to try to get maximum flow around the tank? Are there any tricks or tips anyone can offer? Such as - should I keep it 'high' in the aquarium and pointing downward? Or keep it low and pointing up? Should I put it right next to the intake of the AquaClear filter and aim it away from the intake? Or put it on the opposite side of the intake and point it towards the intake? Any tips would be appreciated. Thanks!!
