Looking for some advice on LCA dinos (do not want to dose silicates). I do not have a confirm microscope diagnosis. It has not responded to multiple chemiclean treatments or bacteria dosing so far. Nutrients have been 20ppm .2 phos, but trending down as I dose bacteria. I have a 55W UV but from my understanding that won’t help much. Predominately on the sand and disappears at night. Thoughts on how to beat this without silicates?
