Deteriorating Plant Condition

[hadjici2]

Hello people,

I had a healthy tank for the past one year which was growing plants very nicely. I had layers of tetra substrate under the gravel and the Vasilernia (i think thats how they are called) plants and some other plant species were groing greate. I have been in the hobby for 10 years now and through the time I have learned alot so I believe the mystery is down to the details of fertilising. The past year I did not fertilize the water column at all. Only a few times I used seachem Excel for co2. I have 8 tetras a pleco 4 cories and 5 zebra danios along with some ghost shrimp.

The plants now have wholes on their leaves, turn brown and some leafes die of the plant when they are young. I know probably its the substrate that lost all its neutrients. I changes my lights a few weeks ago so my fluorescent lamps are new. I have no algae at all in the tank. Now for a week I dosed the water column as such, according to the dosage mentioned on the bottles:
Day 1: Seachem Excel, Seachem Iron, Seachem Phosphorus, Seachem Potassium, Seachem Nitrogen, Seachem Trace elements.
Day 2: Seachem Excel
Day 3: Seachem Excel
Day 4: Seachem Excel, Seachem Iron, Seachem Phosphorus, Seachem Potassium, Seachem Nitrogen, Seachem Trace elements.
Day 5: Seachem Excel
Day 6: Seachem Excel
Day 7: Seachem Excel

No I am not sponsored by seachem I just like their products

Do you have any suggestions or comments?


Thanks...

Do you know the levels of PO4 and NO3 in the tank at the moment? I would be weary of adding PO4 and NO3 without knowing what the tank is already at.

EDIT - oh and there are far cheaper ways of adding ferts, the dry type cost a fraction of the liquid bottle types.
