I need them.
I have been trying everything to get it started. I have gone to my LFS
3 times and got some scrapings from their tank and still nothing (once a week for the past three weeks). When I put the scrapings in, I shut off the skimmer and just let the PH's blow it around til it dissolves. I turn the skimmer back on the following morning.
I know tank params affect the growth but all mine are in the goldilocks zone now:
My T5HO lights are on 10 hours a day, 8 hours w/ acitinic and whites, 2 hours with just acitinic (dusk/dawn). Anything else I can do to encourage the growth? I've heard of people using 2 parts and/or Purple up to get it to grow but I'm always a little weary of adding supplements.
