I just messed around with Dino's for the last year. Tried Dino X and they were toast within the 21 day treatment. Highly recommend it. I tried everything from no water changes or feeding to black out periods, only to find that they would grow back soon after.

Now that I did the Dino X, they haven't been back.

However, word of caution on the Dino X, inverts will suffer. I have virtually zero pod population now, and my hermit crabs were quite lethargic for quite a while. It also melted down my pulsing xenia. My acans and zoas were fine though.

Chemi clean worked for me with Cyano on my other tank and haven't ever had to do it again...

What is your phosphate reading?

Tested with my Salifert kit and it says it's between 0.03 & 0.1 ppm. :redface: I must admit I was not using it for the last 2-3 months, guess I shouldn't have stopped as now I'm paying the price.

I would dose 5 drops a day of the Foz Down into the tank for the next 4 days and then see where the tanks at.

Ok I'll try that and see how it goes.

Did the 5 drops do the job?
