Nutrient deficiency Eleocharis parvula
I have a small pico tank which has Eleocharis parvula in it amongst some java moss and a dwaft anubias with the aim of growing it into a carpet.
1 gallon (estimated)
5w of light
fine gravel mixed with JBL AquaBasis
Flourish excel dosed everyday
Tropica Aquacare Plus (N + K) added twice a week
Tetra Easy balance added weekly
long story short i added two potted plants last autum and it grew well and sent runners everywhere and generally appeared to be doing well. for one reason or another i then neglected the tank for a month or so and pratically stopped attending to it i.e no feed etc. a green algae like film covered the water surface and the Eleocharis parvula turned yellow from the tip down and started to die off fast. the older growth was affected more. i instantly stepped things up again and started feeding again but the film remained, if i skimmed it off it was back within a day or so. no other algaes were or are present.
I have now cleaned the filter and increased the surface movment and no more green film (yet) and i'm adding Flourish excel each day (1ml) and 1 ml of Tropica ferts twice a week (all as i did before).
So my question really is, have i shocked this plant and have to wait for it to recover? or is it lacking a nutrient which just happend to coincide with me negleting the tank for a few weeks?
i have got the tiniest amount of green algae on the glass of the tank but the snail is generally keeping on top of it. i have the tank full of cherry shrimps after they bred in there so they keep the tank in tip top condition.
These changes have been in affect for 3 weeks now and no improvement? but the yellowing appears to have ceased. and the anubias is strong and healthy and sending out new roots.
