Your tower isn't broken.
It's asking for help.

Empty ports. Yellowing leaves. A reservoir that smells like a fish bowl. The Tower Rescue Guide takes every common tower symptom and walks it back to the real cause — then gives you the fix, most of them in under ten minutes.

• Symptom → cause → fix — follow the flowcharts instead of guessing at solutions
• The reservoir rescue — smells, algae, pH swings, and nutrient creep, each with its exact remedy
• The empty-port revival — the weekend plan that takes a half-dead tower back to full production
