As a side question, can I ask what water source for your tap? Maybe located near the center of the state and surface water like Missouri River? Not saying it is bad, just that lower PH like that is less common in the South end of the state and thinking how different water might be confusing the issue.
Yes, the water source is Meramac River, confirmed with the water company. Ca and Mg vary widely according to the report, so that's why I went and got GH and Ca test kits.
Here are a couple full tank shots - one just happened to be during a water change a couple weeks ago, and then a shot from tonight. I sold quite a few stems the other day so things look a little sparse.
Most plants are growing OK - Ludwigia Palustris, Bacopa, Acmella Repens, Crypts and Vals are the best. Persicaria SP - mostly good, but a few stems don't grow much. Might need more spacing, but they get great CO2 flow, as does Lymnophila Rugosa. Anubias aren't growing as fast nor are they sending out flowers. L Rugosa is growing extremely slow - no trimming for weeks.
A Reineckii has some ratty bottoms, but new growth is OK. That java fern came loose - I need to fix it back on the driftwood...
Lymnophila Belem - another one with no growth to speak of, no stunting, and not much color:
Ammania Senegalensis - just a hint of better growth lately. I know it likes lower nutrient levels, so we'll see if it comes around. May need a substitute for it at some point. Months ago I grew it well enough to sell stems regularly.
Lastly, here is hygro after a trim - not filling in that well. It gets pinholes below the top 2-3 nodes.
Lighting is a BML dutch XB at about 80% strength, a T8 single bulb and twin T5HO on the bowfront, with Floramax and Colormax bulbs. Estimate par at maybe 70-90. Lymnophila Belem is toward the front, and doesn't get as much light as other plants. But, it's enough to grow algae on older Anubias leaves at that spot...
