About 4 months ago I added some hygrophilla corymbosa to my heavily planted well established 29 gallon low light/low tech tank figuring I would give this plant a try. All the plants I already had in there were over a year old and doing fine and were showing good growth. The only ferts I was adding at the time was Seachem Comp. once a week. The hygro started to turn yellow around the edges and was developing holes in the leaves. I added some Flourish potassium for the holes and some Flourish iron for the yellowing. That’s when all hell broke loose in my tank.
All of my anubias (I have at least 25 of different varieties) started to turn yellow around the edges. I stopped adding iron and potassium (still adding Flo. Comp.) but the leaves keep turning yellow. Everything I have tried has had no results. I even added some new anubias about 3 weeks ago and those leaves are starting to turn yellow. The hygro has since died and been removed.
What I don’t understand is that I have a 10 gallon tank right next to the 29 and all of the plants are healthy. The only difference between the 2 tanks is that the lights are the same. This obviously means that the 29 gets less light because of the greater depth of the tank. But again everything was OK until I added additional ferts.
Tank Parameters:
Lighting: Life-Glo 6700K T8 15W Only about 6 months old
PH 7.2
Ammonia 0
Nitrite 0
Nitrate 20
dGh 9
dKh 6
TDS 265
I ordered a new bulb online and that will be here in a couple of days but I don’t know what else to do.
If anyone has any ideas I would sure appreciate some help. Again please remember I didn’t have any problems until I added iron.
Thanks in advance for any help.
