David W Posted November 18, 2020 Share Posted November 18, 2020 Thank you in advance for any advice. This is a 10 gallon tank, with a betta and nine neon tetras. There are a number of small ramshorn snails. The substrate is Seachem flourite. It has been set up for 4 months, so more time needed for a good balance. 30% water change weekly. 2 pumps of easy green after the water change. Lights are on 8.5 hours. Currently no signs of algae. Current water parameters Ammonia - 0 ppm (API Liquid Test) Nitrite - 0 ppm (API Liquid Test) Nitrate - 30 ppm (API Liquid Test) PH - 7.8 (API Liquid Test) KH - 60 ppm ( API test strip) GH - 80-100 ppm (API Test Strip) I have a liquid kh/gh test kit on the way. I'm not feeling the test strips. I have three weeks ago added Pothos and let some stow away duckweed do it's thing. I had some staghorn algae which went away about a week later. Recently the Pogostemon Stellatus Octopus started developing pin holes in some of the leaves. From the deficiency charts I'm inclined to think it is a Potassium deficiency. Does that seem correct? I surmise that the pothos and duckweed are sucking up too many nutrients. Right now I am trying to up the easy green to three pumps a week. I started on Saturday, and will keep an eye on over the next few weeks before making another change. Any thoughts on this diagnosis and approach? Would root tabs be more appropriate?
