Thanks for the response! This is only my second tank and still learning. I just assumed with a name as “Easy Carbon” that it would be a form of liquid carbon so I am not injecting any form of CO2 to assist with plant growth. Stupid mistake on my end. In terms of the hygro, it has shown new growth in where I had trimmed and replanted throughout the tank. It has been like that for about 2 weeks until the yellow spot appeared and up to now that area has gone clear. I have placed 1 tab next to that specific hygro since every other hygro has been shown to be healthy. If I didn’t mention, my might timer is set from 8AM-5PM.
I forgot to add. I can’t use my tap water. Even with a conditioner nothing survives…I purchase RODI water and use Seachem Alkaline / Acid buffers together in 5 gal buckets. Since I made this in excel. I’ll change total gal as needed, etc.
Please ignore some of the notes since that’s the printout for my 20 gal at home with higher ph, GH, and KH for mollies.
the tank in this thread has a printout with it at my office.
