An under-gravel filter is pretty much
what the name implies, a filter beneath your aquarium gravel or
substrate. It is made up of a perforated or slotted sheet of plastic, slightly
raised above the base glass to allow water flow downward, through the gravel
and up again through “uplift tubes”.
With the increasing popularity of planted tanks and aquascaping, a few people are asking questions about High Tech or Low Tech setups. In this post I will try to answer a few questions on the subject, without getting too technical (no pun intended)…
What is the difference?High Tech setups uses CO2 injection, an intensive fertilizing schedule and specialized high intensity lighting. Low(er) Tech setups run on standard lighting, the occasional addition of fertilizers and mostly no additional CO2
hear people ask what the difference is between a Planted Tank and Aquascape.
Although it may sound like a straightforward question and an easy one to
answer, there is quite a bit more to it than that.
