hI everybody
I introduced plants to the tank about 10 days ago but they appear to be dying,they are going a rusty colour some more so than others two of them look ok and haven't changed much since the introduction.The lfs person couldnt tell me the names of the plants so these are from pictures I have found on the net and imo they are as follows

1.LILAEOPSIS MACLOVIANA(1)
2.VALLISNERIA SPIRALIS(1)
3.ANUBIAS(NOT SURE OF THE EXACT TYPE)(1)
4.JAPANESE FAN/DWARF GREEN ACORUS(1)
5.SPATTERDOCK(1)
According to my lfs these are easy plants to begin with, I have been feeding them once a week and they are rooted in approx 2inches of substrate(sand/gravel mix)any suggestions as to what I'm doing wrong or what I should be doing would be appreciated

#4 is not an aquatic plant. check out and see it the lighting you have is good for the other plants.

HI nips

Could the rust colored spots be brown algae (diatoms)? It's common in new tanks. Ottos will eat it.

Here's an article about brown algae:

Here's one more:

Sometimes when too much micronutrients (trace elements) can make the leaves appear a rust color.

I don't know any of the specifics of your tank. I can only guess at what the problem may be. Here's some info about the roles of nutrients:

thanks for the info you posted very helpful one more thing if I may,
does running an air stone for prolonged periods damage plants/plant growth in any way

You're very welcome for the info. I hope that it helps.

Plants use CO2 for photosynthesis and they breath O2 24/7. Running an air stone during the time that the lights are on and the plants are doing photosynthesis drives off much of the CO2 because of surface turbulence. If you have enough plants and they are growing, you really don't need an air stone at all because of the O2 amount that plants make.

If you tank is lightly stocked with fish and plants; try leaving the air stone off when the lights are on and cut the air stone on only at night when the plants aren't photosynthesizing.

Water can be 100% saturated with O2 and water can also be 100% saturated with CO2 at the same time. The saturation of each is independent of each other.

Another thing that will drive off CO2 is a filter. The turbulence caused by it drives off CO2 and adds O2 by it's design. Keeping the water level high minimizes that problem to a certain degree and helps to conserve CO2.
