Don't change your Triton fluorescent tubes -- they are effective until
they shut off! This is another big advantage of them and their patent.
If anything, replace the one that is not a Triton as it goes "down

Be sure that you are not putting any of the leaves from the stems of
the "bunch" plants that you mentioned under the gravel. You must strip
the leaves from the stem that is being planted. Leaves under the gravel
cause the stems to rot. Also, if your water is very soft (lacking
calcium), put in a clean clam shell or some oyster shell. These plants
Your "Fervorit" is not causing the "thread algae". Use it according to
directions. You have "thread algae" because your rotting stem problem
is causing the other plants to not grow as well and the energy produced
by your light has to be utilized -- or "Mother Nature" forms her own
plants (your thread algae) to utilize the energy.
