Healthy
fish tanks contain crystal clear
water. No piece of aquarium equipment comes close to
the water clarifying value you get in an under gravel filter.
UG filters never really wear out. If
you break a part, you can usually glue it together or buy a replacement
piece. In recent years we’ve
seen a great increase in new brands and styles.
They all work great! And they work several times better than
the ones we used last millennium. Actually, we probably still use at
least 100 of them over 20 years old.
Regulates Temperature. Because
the UG filter pulls water from the bottom and pushes it to the top, it
circulates your water. It
turns it over 24 hours each and every day.
Every part of your tank maintains the same temperature level.
The closer you keep your heater to one of the lift tubes, the
better it works.
Aerates Your Water. When
your lift tubes bring water to the surface, this causes that new water to
come in contact with atmospheric oxygen.
This turnover (not the bubbles in the tube) adds oxygen to your
aquarium. Your UG filter
serves as an excellent aerator.
Clarifies Your Water. We
usually stress the biological advantages of the UG filter, but it also
performs mechanical and chemical filtration.
By pulling water down through the gravel, it pulls debris into the
gravel where it undergoes many changes.
Sticky bacteria live on the surface of each piece of gravel.
Their presence keeps loose particles and unwanted miscellaneous
bacteria from clouding your tank and causing problems.
It takes six to eight weeks to build up these sticky helpers unless
you add a handful of aged gravel or bag of dirty water strained from a
functioning UG filter -- out of one of our African cichlid tanks.
Removes Wastes. Other
helpful bacteria grow on your gravel at the same time.
These “eat” the most harmful part of the fishes wastes –
urine – and convert it into relatively harmless substances.
The final byproduct of their meals is a substance called nitrate.
Even in high concentrations, it rarely bothers fishes.
Nitrates are also the form in which plants – including the algaes
that fishes love – eat fish wastes.
Filters Chemically. Most
people ignore this factor, but UG filters can also be used to change the
chemical composition of your water. You
do it with those cartridges that fit on the ends of your lift tubes.
If you use refillable cartridges, you can alter the chemical
composition of your water at will.
Carbon removes heavy metals, complex organic proteins, colors,
smells, and medications. In
other words, carbon takes out nearly all impurities.
In saltwater carbon can remove trace elements. Mariners
usually skip the carbons.
Water Softeners, otherwise known as zeolite, take out the
carbonates (lime, basically) and replace them with sodium.
Softeners won’t work in saltwater.
Ammonia Removers of the zeolite type also won’t work in saltwater.
Use AmQuel instead to remove ammonia – the most harmful
part of the fish wastes. It’s
especially helpful in new tanks. AmQuel
keeps the ammonia from harming your fish, but still lets the helpful
bacteria eat it. Established under gravel
filters really don’t need ammo removers, because the
bacteria do the same job for free.
Provides Huge Filter Capacity.
Compared to any other filter, the UG holds the most trash before it
need to be cleaned. The entire
floor of your tank filters the water, not some little box or pad.
UG filters collect tremendous amounts of wastes within their system
before you need to clean them.
Easy to Maintain. UG
filters eat up the liquid portion of the fish wastes.
This is the harmful part. However,
fish feces – the solid part – keep building up in the gravel.
This constant build up clogs and eventually slows the filtration
process. The water then seeps
through the gravel at a very slow rate.
The solution? Clean
your gravel.
Clean Your Gravel. In
the old days (many decades ago), we used to drain the tank.
Carry it to the sink. Rinse
the gravel. Refill it with
water and start over. In
addition to being a great deal of unnecessary labor, this method also
created as many problems as it solved.
We cracked lots of tanks. Sterile gravel keeps your filter from working the way it should.
Then we hit on the idea of using large diameter siphon hoses to remove the
gravel with a portion of the water. We’d
rinse the gravel in a large bucket and return it to the tank.
This cut the work in half, but still made a real mess.

When you use your gravel vacuum cleaner, don't ram it thru your filter
plate.
Use a GVC Gently. Now we use a
much more efficient system. We
use a handy tool called a gravel vacuum cleaner.
We clean the gravel, change the water, keep the plants undisturbed,
don’t upset the fish, and don’t even stir up the water.
Best of all it keep us from carrying tanks.
If you’ve ever cracked a tank in your sink (or even cracked
a sink), you know why we like gravel vacuum cleaners so much.
This glorified siphon picks up the gravel, swirls it around, rinses the
gravel, removes the fish feces, and totally rejuvenates your UG filter.
We clean 20 or more 20-gallon tanks in an hour.
We can’t recommend GVCs too highly.
They take the work out of cleaning your tank.
