Rachel, I live in Portland also and have no problem growing Crypts in my 29
gallon tank. Now I don't have many in there but they pretty much grow like
weeds. And I only have 36 watts on the tank. I'm wondering if you are
lacking either a micro or Macro nutrient?? What are your Nitrate and
Phosphate values? Do you add trace elements? Do you add Iron?
