Question: Holes and Potassium?
Hi All, Neil Frank, David W., Karen Randall, and George Booth all come to
the conclusion that my new, emerging Echinodorus leaves get holes in them
when I remove the older, outer leaves because I am taking away a nutrient...
potassium. What aquarium brand fertilizer can I use to supply more
potassium? I can't think of a product for sale with potassium listed on the
label. If there is one please let me know what it is so I can buy it.
Could I put a banana in the substrate? ;) Should this be supplied in
liquid form or be put in the substrate around my Echinodorus? I am under
the assumption that Echinordorus are root feeders and won't take much in the
way of nutrients through the leaves? I am under the assumption that
stem/bunch plants take most of their nutrients through the leaves and less
through the roots? BTW, I got my water report and it checks out with my
test kit readings of 1dh of KH and 6dh of GH. The alkalinity also checked
out the same 10 mg/l. The test kits were right in step with the water
company. I was surprised to see this. I add nothing that I know of in the
way of acids. I use API Stress Coat and API Tap Water Conditioner to
dechlorinate the water. The low alkalinity must be the reason my pH falls
to 6.0. I think I will try the baking soda that was suggested to bring the
KH and pH up, and then go with CO2. I want to thank all of you for your
help. I need it. <G>
