check Ro/DI filters
Procedure:
1. When the reading on the right-hand TDS meter (set to “IN”) displays 50% of the reading on the left-hand TDS meter (set to “OUT”),
it is time to replace the MAXCAP® DI cartridge.
2. Follow the directions on page 5 to rinse up the MAXCAP® DI cartridge.
Procedure:
1. When the reading on the right-hand TDS meter (set to “OUT”) displays “001”, it is time to replace the SilicaBuster ™ DI cartridge.
2. Follow the directions on page 5 to rinse up the SilicaBuster ™ DI cartridge.

check Ro Membranes
Procedure:
Rejection of the RO Membrane Calculation Example
1. Tap water TDS = 150 ppm (X)
2. RO water TDS = 15 ppm (Y)
3. X - Y = 135 ppm
4. (X - Y) ÷ X = 135 ÷ 150 = 0.90
5. Rejection = [ ( X - Y) ÷ X ] ×100 = 0.90 ×100 = 90%
Rejection rates less than 95% may indicate that the membrane should be replaced.

- SANITIZING SYSTEM - ( It is recommended that you sanitize the system once a year.)
1. Turn tap water source off and remove all filters from the system, including the RO membrane
2. Mix together hot water, soap and a little bleach.
3. Scrub filter housings and rinse with clean tap water to remove soap and bleach.
4. Place filters back into housings and reconnect lines.


Every 2 years.... Starting Oct 2011

Now, the "too mature" system is the old tank syndrome. Happens in nature, too. That whole forest fire reinvigorating the system is true.
Equally true on coral reefs where the intermediate disturbance hypothesis is the running thought on why coral reefs maintain very high
diversity...they are stable, but not too stable, and require storms, but not catastrophic ones....predation, but not a giant blanket of
crown of thorns, mass bleaching, or loss of key herbivores.

This goes to show what good approximations these tanks are of mini-ecosystems. Things happen much faster in tanks, but what do you expect
given the bioload per unit area. So, our climax community happens in a couple years rather than a couple of centuries. Thing is, I am fully
convinced that intermediate tank disturbance would prevent old tank syndrome.

An unwary aquarist is most likely to be rudely awakened to Old Tank Syndrome when he attempts to add new fish to his existing collection.
Many fish "shock out" upon introduction to this very different, harsh environment and simply perish within a few hours. Others may survive
the initial shock, but the acute stress of this radical change in environment weakens them, making them more susceptible to infection.
Ironically, disease-causing parasites may well be so successful at attacking these weakened fish that they quickly multiply to epidemic
proportions, and wreak havoc on the original residents as well.

The aquarist might be inclined to blame the dealer for "selling sick fish"; after all, he hadn't lost any fish or seen a sign of disease
in several months - or maybe years - before making this purchase. "Obviously," he argues, "there's nothing wrong with my aquarium, or all
my fish would have died long ago". But that isn't necessarily the case. The original inhabitants had the opportunity to become slowly
accustomed to waste buildup. The hardier specimens adapted to the chronic stress and survived. Weaker individuals were overcome one at a
time, perhaps over a period of months, and their deaths attributed to natural causes.
