18000K is not an appropriate freshwater bulb. Most of the light the bulb puts out is unusable by freshwater plants. You should buy one that is about 6500K. I think this is your main problem. Also, 15w over a 14g tank is low light, perhaps too low to grow anything no matter what fertilizers you put in it. Can you add another 15w bulb so you have 2 on your tank? Even for low light it is on the ultra low side, moss and ferns might work.The tank is a 54l/14gallon with an old 15w t8 18000K POwer-glo from when I quit the hobby a couple years ago.
An unusual substrate, it might work, but it is not something many people use. It will likely make the water quite soft.Soil is two fists of boiled peat covered by 8 litres of some burned clay substrate that I don't know the name of.
I'm not familiar with Micro+, or is it the same thing as intermag mikro plus?mixture of 25ml of micro+ in 500ml of water
micro+ is Fe 20g/l, Mn 10g/l, Cu 0.52g/l, Zn 2.9g/l, B 4g/l, Mo 0.75g/l
From this I have dosed 5ml of KNO3, Kh2Po4 and K2SO4 on day 1,5 and 7
Also dosed 5ml of Micro+ on day 5 and 7
This is certainly a problem. Water circulation is necessary for proper plant growth and it helps tremendously. I don't think it is the cause of your current problem (you need more light), but it will probably cause issues down the road if your don't get a small powerhead or device to move the water around. You don't want to have something splashing in the tank like a bubbler, but you do want water to circulate and prevent deadspots from appearing.No technology has been used in the tank, no filter or heater. Could this maybe be the issue? Lack of water circulation?
Bacteria will create a small amount of circulation but I'd argue not enough to solve the problem. You really do need a small pump or something in the tank to move the water around and prevent it from going stagnant.The guy in the store said that the soil would create circulation through bacterial activity that would create warm water in the soil which would rise. It is also meant to work as the filter at that point, but it is maybe not very active now without fish and daily feeding?
Why the break?Lights are on 9-13 and 15-20
I'll wait to see the photos before giving a more concrete answer but this description coupled with the [lack of] lights is most likely the reason the plants are dying.Green color fades on some plants on the ends of the leafs or whole leaf.
Brown/red spots on some plants and in general the plants don't look as sturdy.
