Ph is an ongoing
concern for reef keepers and aquarists. Typicaly it is a concern
more focused towards reef tanks because fish tanks can tollerate
a larger flux in Ph levels before causing irreversible damage.
In contrast a reef environment must maintane a constant Ph level
in order to sustain life. The best Ph level in a reef tank ranges
between 7.6 and 8.4 and best suited to the higher side of that
range. The normal behavior of Ph in a saltwater tank tends to
be on the acidic side (low) Here are some reasons for this.
2)Too much carbon dioxide
3)Natural acids created by metabolic waste
Sea water contains natural buffers like bicarbonate, borate,
hydroxide and others that restrict any drop in Ph levels. One
easy fix for a drop in Ph that is often used is baking soda which
contains bicarbonates. Another dreaded method is to do a water
change, this should replenish the natural buffers and minerals
in your tank. One big reason for a drop in Ph is left over food
and fish excrement so removing these things from time to time
could be of some benefit.
