Aquarium Filter Salt Water

Actually, though, the lemon tetra is quite colorful on close inspection. Body coloring is a delicate pale yellow, flanks are silver, and the leading edge of the anal fin is shiny-bright-yellow and sharply divided from the other rays, which are black. In the male, the rest of the anal fin is broad and fring

These low maintenance units are great not only for driving down the accumulation of the "end products" of aerobic nitrification, but also as harbors and cultures of interstitial fauna that can add a great deal of reef fish nutrition. To top it all off, the reductive nature of the denitrator dissolves the calcareous sand, making minera

They look similar to a large T fitting. Water is pumped up through the bottom and the water exits in an alternating pattern from each side.

Just like the Hydor Flo, these units reduce the water flow because they use that pressure to create the alternating pattern. Again, I dont feel like that is a major shortcoming. It is simply a tradeoff that one must make for the wave-like action. That said, I do think these units have one major weakness. They only come with barb fittings, and they are not very good barb fittings at that. I would much prefer if they came wi

Apparently they have never heard the saying that there is no such thing as a free lunch. Of course they reduce the flow rate some. They use that flow to create the spin. If Hydor could create a similar device that didnt reduce the flow at all, then they should reconsider their business plan and go into the perpetual motion machine business. J

I bought my first (and only) Rio Motion about two and a half years ago for my then new 1

Their reasons? They worked. Not much was commonly known as to why. Now we "know" that the aforementioned beneficial bacteria thrive in such settings with their chemical food (ammonia, nitrite, oxygen, and CO2 as a source of carbon) flowing oh-so conveniently by the nooks and crannies living space provided by the "holey" substrate.

Even today, with the advent of macro-algae, reef, "Berlin" and other "live-rock" systems in use providing the same habitat, circulation and buffering advantages, undergravel filtration remains the predominant method of
