Home Aquarium Tanks

I went to remove and clean it again, when it broke coming off. It then went into the trash, and that was the last time I used anything with the Rio name on it, having had several bad experiences with their powerheads as well. For more information:

It is a good idea on paper, and is very similar in operation to those old-style rotating spray bars that came with the first wet/dry filters. These would routinely clog as well and

They do a great job in freshwater tanks. In saltwater aquaria, which has much lower levels of dissolved oxygen, undergravel filters should not be used, as the submerged aerobic bacteria in the gravel are competing directly with the fish for oxygen. It was this fact, that led to the invention of the wet-dry filter in the 1980s. The use of aerating power heads helps eliminate this problem t

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

Rio Motion

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

Valves are not emphasized here as they add considerably to expense, are generally not needed, and complicate a delightfully simple application to excess (creating a "juggling act" with one adjustment affecting all). Another concern is that if the manifold does not have enough outlets, there will be undue pressure placed on the pump (generally harmless for magnetic drives, but perhaps harmful to direct drives). On the opposite end of the spec

In general: the primary excretory product of fishes and invertebrates is ammonia (whether theyre fed or not). Were it not to dilution by water change, chemical filtrants and/or biological filtration ammonia would accumulate to toxic concentrations.

As the story goes ammonia is converted to nitrites by way of microbes, notably by Nitrosomonas bacteria. Nitrites are in turn changed into nitrates by other microbes, especially Nitrobacters. This assortment of populations takes a while to establish itself

Daphnia For The Aquarium

Daphnia are a great food source for both young and adult aquarium fish, you could catch them with a net in a pond, but their's a risk of bringing in parasites. I just found an article about growing daphnia yourself, nice read for the real tinkers out there :-)
