Honestly, it does not look like cyano
to me. However, the quality is not great so I could be wrong. You might have some diatoms, normal die off, and a touch of cyano
. Test your water and only use distilled or RO
water. There are too many problems with tap water. You can buy a filter that will attach to your sink and will help with any bad stuff in the water, thus you could use it for the tank. However, it is not the ideal way to go. I am currently just using a duel stage filter on tap water, it is not RO
. I have no more cyano
, after dealing with a major bloom and fighting it for a year.
Do I spy a decorative rock/coral that is not real? I see something that looks like it might be made out of plastic. If it is, I strongly urge you to remove it asap
. It will only cause you problems down the road.
