Unfortunately few days after removing the cyano came back.
After trying many different products and technics, I think I finally found the perfect working product: UltraLife Blue-Green Slime.
Within a week 100% of the cyano was gone and never came back so far. [emoji4][emoji106]
One month has passed, quite happy with the overall growth. No major issue to be reported. Back to standard WC plan with 50% weekly.
Little bit of cyano to fight with but I guess it's normal until the parameters get fully stable.
The new ADA Amazonia v2 soil was great to set and didn't make the water messy which is great but wow this thing releases A HUGE amount of ammonia in the water!
I have done daily WC the first week otherwise ammonia and nitrite were sky high!
Now everything seems fine, no fish loss [emoji7]
Thanks for your messages guys.
I really like my Thermo600 pump however I agree that the heater isn't the best quality. I could see after only few months of use that the inside was getting kind of burnt with oxydation already.
