So Byron if you would throw some suggestions out there on T8 bulbs and fixtures that would be awesome.
About my plant issue, I have been using Madison tap water from deep ground aquifers for the aquarium, that about says it all. It's just not plausible for me to get to a store to buy RO water as I do not have a car. So my GH is around 400-500 ppm while the KH is just a little bit lower at 250 ppm or so. Initially I thought to try a softening pillow but have since given up on that, not looking to fluctuate the hardness for the fish. Unfortunately I do not know the pH. And I do not add any ferts.
I'm really not sure what is out of order obviously but I have read that Water Sprite
is easy to grow and it is sure is dying well in my tank so something must be wrong. With that said, the other plants like the red Ludwigia
and moneywort are doing decent. Growing slowly but not thriving by any means. How much of a difference will kicking up the light to a T8 make and with this limited information what do you think could be the matter?
What is your present light fixture? I earlier assumed fluorescent tube, maybe that is incorrect. Do you have this (which would be T8, the "normal" tube fixture), or do you have incandescent (screw-in bulbs)? You can have very good plant light either way, I will suggest tubes/bulbs when I know the type. [You type 2g, presumably you meant 20g at 24 inches length.]
Your water is very hard, 22-28 dGH. This might be part of the issue with Water Sprite
, it is a soft water plant and while it should adapt to harder water I'm not sure how far this will go. But before we worry about that, a liquid fertilizer is probably needed, as there may not be sufficient nutrients from just fish foods breaking down. I recommend 2 that are complete, Seachem's Flourish Comprehensive Supplement
or Brightwell Aquatics' FlorinMulti
. With either, make sure you get these exact products, as both manufacturers make several different products under these names. It takes very little, for a 20g no more than half a teaspoon once or at most twice a week.
Another point is that plants take time to adjust to different water and environment. No idea how long you've had the Water Sprite
, but mine will fall back just moving it to another tank with near-identical water and light. If you have had it more than 6 weeks or so, it should be adjusted from this.
You should get an API pH test kit. The pH and nitrates are worth checking periodically, as sudden changes can alert you to trouble. You might find out the pH of the water from the Madison water supply people, which presumably is where you got the GH.
