sufficient light, harder water (in condition that plants can live with it), 10 hours lighting period will do the job. colder water temperature will help a lot but it is not vital.
This is a common rural technique to farm floating plants to feed fish for quicker growth at lower cost in China, with a lot of academic research projects on optimum conditions to farm floating plants and research reports published.
I checked it again and It should be Pistia stratiotes with English names as water cabbage,water lettuce. It can develop into giant shape if the water is fertile and sunlight is strong. However, I read a study on some floating plants that they can absorb nitrate and store it in their body when...
Try Spirideka Polyrhuiza if you can locate it in your region. This plant is using its long roots to absorb nitrate. However, it can only grow well in a very nitrate-rich still water body. So it will soon turn into smaller shape and even rot if nitrate is not sufficient to support its fast...
turn off the filter to make water surface still. using fine net first (wave the net in one direction to drive the tank water moving into a circle). this will take most of the trimmed leaves out. then siphon (keep the flow small so it can last longer) out the last remaining leaves. it will take...
If the water is very hard, you need to use another type water softening resin revitalized by HCL, not by salt. So the resin will not replace much sodium into the water.However, you need some know how to handle this. At least you need to have a PH probe.
Or you may use Potassium Chloride to...
bulb manufacturers have been demonstrating the "ideal" wavelength of their "growth type" bulbs all the time. So the peaks in blue and red spectrum sensible to plants mean something or nothing?
A shutt off Co2 cylinder with a normal valve usually won't explode into fragment. It will fly up like a missile if there is a leak at the bottom (usually rusted through, or a leak hole patched by welding). It is still in one piece, but with a big torn opening at the bottom.
Caution should be...
Thanks a lot for your advise, Drouthie. I will try to stay at the upper wind position.
Actually 25% of liquid itself does not have much smell. 2% of diluted has a light smell like green apples.
We buy glutaraldehyde from local chemicals stores (not UK). Usually two types, 25% and 50%, AR purity, packed in a 500ml brown colored glass bottle (with 250ml content only).
We use RO water to dilute with a graded dropper (2-3ml). No need to wear any protective things if you open the bottle...
A lazy way is to find some small pieces of stainless wire mesh, put HC cuba on it (well spread), and cover them with a nylon mesh, and then bury (does not matter) the stainless wire mesh into the gravel again.
My wild guess is that : Have you ever turned it off completely for a night? It may be caused by the check valve (against water flowing up) has been soaked with water sucked in. When you turn the system completely off, the regulator will suck the water up, and if your check valve is not strong...
