Hi,
I am starting to see some holes developing on some of my crypts - see attached picture. I am curious to what kind of deficiency (if any?) that might cause this.
My two 40 US Gallon tanks are low-energy but heavily planted: No CO2 injection, relatively low light, but on 11 hours/day and low fertilization (24 ml Tropica Premium after weekly 40-50% WC and 20 ml Tropica Specialized mid-week). I used to use dose Nitrogen and add root tabs but haven't done so for a long time.
Cheers,
Michael
