Heaters come in sealed submersible or not formats. Get and use the former only. If you need one of two-hundred or more watts, get two of two thirds or so of that wattage each and place them in separate ends of the system, not in a sump. Place the heaters low in the tank (but not undergravel) to facilitate heat diffusion, and prevent you from breaking them. Most heaters are accidentally broken by removing or replacing them when theyre too darn hot! The should be set in the tank water for fifteen minutes plus before plugging in, and unplu More |
Some anaerobic denitrification does occur in every system; but not enough to offset the forward accumulation of nitrate. There are filter module products that portend to promote these microbes and their beneficial activities. Like dating, I urge you to be careful in their selection and use. Many (dates and denitrators) are "high-maintenance" units requiring daily fooling-with. All have the potential defect of other anaerobic production toxifying your system. Finally, in my opinion, theyre just not worth the hassle, cMore |
However, in contrast to a standard multi-strip, only three of the plugs have power 24/7. The other three plugs are connected to a controller knob and turn on and off in an alternating pattern. Plug #1 runs for a set period of time and then shuts off. When #1 turns off, #2 turns on and runs for the same set period of time. So, #1 and #2 are always opposite of one another. The #3 plug is a little different. It will turn on and remain on all the while #1 and #2 operates for one cyclMore |
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 More |
And since Oscars are large and very smart cichlids, you can actually teach them tricks, they might want something to do like digging up plant. Be careful, they are enthusiastic eaters and they love to eat smaller fish. Thus, only keep them with other fish that are of the same size. Temperature is important, and should be kept stable somewhere in 79-86F range. Feeding Oscars is not a problem since th More |
