I have had a 20 gallon going for 8 years now. I had given up on plants but decided to try again a month ago. I decided to try the low tech, no c02 method discussed here,
My light is 2x14w t5 and I have an Ehiem Ecco filter. I have very soft water here in NYC. I am dosing 1/4 equilibrium weekly, 1/8 kno3 weekly, 1/32 KH2PO4 weekly and one cap full of Flourish trace weekly.
My java fern is dying, even though all my other plants seem to be doing ok. They are getting brown spots that spread and take over the whole leaf. I assume it is a nutrient deficiency of some sort. Could it be a low KH, as I haven't added any baking soda. Or could the light be too bright?
I also noticed the new growth of green temple is very yellow. The new growth of the crypts seems odd with very small yellow spots. I thought the low tech method was supposed to be easier!
