Hank yes we made a lot of mistakes but that is the best way to learn. With the internet we have thousands of people with opinions and when you have so many opinions we get into trouble. As I said, someone will add a seahare to their tank, the hair algae disappears and they think the seahare ate all the algae or they feel a cleaner shrimp will cure ich. I rarely reply to those posts anymore because as I and anyone with experience will know, it is nonsence. I am tired of trying to explain it to all of the hordes of people who take this stuff as fact. We (you and I and all the other old timers) had to read books or learn by trial and error and we had no one to tell us right from wrong. Now we know better. We have had to deal with hair algae for years many times and we know how to control it. We also know exactly what cures and prevents ich. I can write pages on it and someone will post something like "get a cleaner wrasse and your problems will go away". That sounds so easy so people follow it. No it does not work.
Ich and hair algae disappear on it's own most of the time but you can say that a thousand times on the internet and I can bet that in ten minutes someone will post, get a cleaner shrimp and seahare to fix everything.
I think I will just go and shoot myself.
