Avalon you are my personal God of Latin plant names. Thank you a million. I have a hard time identifying plants and it would come in real handy on sites like the Krib if I knew what I actually had. An interesting comment on plants. For months now I have been adding Flourish liquid fertilizer, but things grow so fast that it was costing me about $7/week on this tank alone, and I'm living on a student's salary, so I switched to adding Ferrous Sulfate daily instead. For about a week or so, the plants looked pretty bad, especially my nitrate hog anacharis. But after this period of "shock", things really turned around. My whole reasoning for having so many plants is to cut down on the work I have to do to maintain cleanliness. But anacharis was growing an inch ar so a day with the Flourish. Now, with just iron, it grows much thicker, with longer fuller leaves, but not so spindly. I have not trimmed anything in 2 weeks now, and it doesn't really need it because everything is growing denser and fuller, NOT taller,which is how it was with Flourish. Everything is nicer except for an amazon sword which seems to really miss something that was in the flourish that it's obviously not getting now. Any plant nutrient wisdom? Potassium maybe? I tried adding potassium gluconate, but it didn't seem to dissolve well. Maybe I should try potassium chloride instead...
