 | When I first started keeping fish, I was concerned about "dead spots" in my aquarium. I then had this crazy idea: what if I hooked up a submersible pump (power head) to some PVC pipe that ran along the bottom of the aquarium? It's been several years now and I have been extremely pleased with the results. The water movement in the aquarium is superb; there are no dead spots. And by adding a sponge filter to the submersible pump(s) I have been able to keep the bottom of the aquarium spotless. The need for vacuuming the substrate has been completely eliminated. In fact, after 6 months of not vacuuming, I decided to test the effectiveness of my undergravel jets (ugj). Literally, nothing came up; it was perfectly clean. - [Details] |
