Advice needed

Hi all
I have a 200L planted tank. I decided to buy a fluval plant 3.0 to help growth. It's a non co2 injected tank but I do use root tabs and liquid fertilizer. Since the light has been put on I seemed to have good growth but some of the leaves seem to be yellowing with pick prick size holes forming or the new growth seems to be speckled. I've never noticed this before. Am I missing something? Thanks

Sorry I thought I have enough info.
Size of tank - 200L
Filtration - fluval u4
Lighting - fluval plant 3.0 - 10 hours a day
Substrate - gravel and fluval stratum
Co2 - no
Fertilizer - flourish - just under inner capful once a week after water change. Easy life root sticks - placed at roots of plants.
Water change - weekly 25%
Plant list - anubias, java fern, Amazon sword, Monte Carlo, water wisteria, crypt, Limnophila sessiliflora, possibly Ludwigia repens and a one I cant remember the names of.
Inhabitants - 4 bamboo shrimp, 10 rasbora, 6 neons, 3 Cory's, 2 gobys, 3 male guppy's and juvenile guppies (female removed) 2 pygmy Cory's, 3 Siamese algae eaters, 2 Otis, 1 bristlenose
The plants I can't remember the names of are the ones going yellow (useless I know). I hope that's enough info. Thanks

Thank you. This is the full tank shot. I can try and get a better shot when I get home if you need to see more.

Hi
You have various issues going on!
How long ago have the plants been planted?
What flourish are you adding?

Some of the leaves look as though the have been lunched on!
Lighting should be reduced as your not adding Co2!

The plants have been in there a month or so.
Reduce the lighting in what way? Less hours or less brightness?
What's likely to be the culprit for munching?

The plants will still be adapting to life under water and to the unique conditions in your tank.
Reduce the lighting in what way? Less hours or less brightness?
A 6 hour photoperiod is a good place to start. Reducing the intensity would also be a good idea especially in a low-energy set up.
Once your plants become established and the tank matures you can gradually increase it. 8-10 hours is the max recommended.
It might also be an idea to buy some floating plants and plants that grow across the surface like vallis.
What's likely to be the culprit for munching?
Your Bristlenose. Feeding it lettuce or any number of green vegetables will help prevent further damage.

I think this only has micro nutrients, the essential NPK or macro nutrients will be missing.
You would be better off with an all in one ready mixed fert like TNC complete.

If you haven't already take a look at the Tutorials section. Specifically, this guide to low-energy tanks it might be of help.

Hi
Lighting...both!
Never used Flourish....but I think it's basically a Micro/Trace fertilizer.
Bristlenose...likes a bit of Salad at lights off.
Plants are transforming to adapt to underwater life...so you will have some leaf dieback till new leaves appear!
You need to add Macro fertilizer.....the yellowing could be a lack of Nitrate!

Hi
Floating plants have various benefits....blocks excess light as you say!
A filtration aid drawing excess nutrients from the water column....especially in a new set-up when the aquarium is in the maturing stage!
A good visual idea of low Nitrate!
In fact, there are stem plants that can be used for the same purpose, see the below link.

I think I will try to get some floating plants, I'm a bit worried about them just being blown around the surface by the filter or getting clumped up in a corner. I've never tried a floating plant so not sure what would happen. Will any of the stem plants I already have work for this purpose? If I buy and use TNC complete would the full dose be too much for a non co2 tank? With the damaged leaves in the tank at the moment, should I prune it all back so the plants can focus on new growth and the good leaves? I can remove the bristlenose and put her in another tank so hopefully stop plants being eaten!

Hi
The ludwigia Ive used the the past as a floater/filtering aid.
The Hygrophila corymbosa might be a option.
Remove damaged or discoloured leaves by peeling off or snipping off.

I would dose as per instructions on the bottle....i think there will be a option for non C02!
