Learned that I do not have cyano ( thanks, Brad!) instead have red turf algae.
I went nuts on water changes, chemi clean and Zeozym and more water changes the last 4-6 weeks...
So, went the the LFS and picked up five mexican turbo snails and eyeing on a rabbit fish to work on the red turf.
After another 20% water change today I checked the PO4 level with the Hanna...
.23... Almost fainted... Did another test again and the same result...
Then it hit me... I forgot to divide by 1000. Need to convert from ppb to ppm.
