I won the battle but lost the war

[Dearth]

So I've been fighting Cyanobacteria for better part of 6 months now I finally am winning the battle did chemical treatments times 3 (lasted a week before coming back enmasse) manual removal and finally went to lights out for a week now slowly going back to normal light cycle and discovered I have had causualties

Lost most of my pods again
Dragonet is not happy
Lost 5 coral to cyano creep
Lost 3 of 4 tiger tail sea cucumbers

I won the fight but it cost me dearly and as far as I'm concerned I won the fight but lost the war
