Hi All ,
First of all, I just found this forum. It is awsome, it has so much information and great advice. I cannot believe it is the first time I come across it.
Here is what I have:
180 gallon aquarium reef ready, three years old set up
39X4 t5HO bulbs 6700k
39X2 t5HO bulbs 10000k
39X4 t5HO bulbs plant grow (current pink light)
pressurized co2 system, reactor
rena xp4 filter
sump with 900 gallon/hr pump
closed loop system for co2 reactor on sump,
flourite substrate, root tabs every 6 months
dosing KNO3, 1/2 teaspoons twice per week
dosing H2PO4, 1/2 teaspoon per week
Flourish Potassium 30 ml twice per week
Flourish 20ml twice per week
pH 6.3
GH 8
KH 6
NO3 ~10ppm
PO4 ~ 2ppm
iron ~0.1ppm
50% water changes twice per week.
Fish:
10 Discus
40 lemon tetras
1 pleco
4 bleeding heart tetra
10 rummy nose tetra
The problem:
In the last 3 months, all the plants are not growing as they use to. The first indication is my cabomba. It is thin and new growth tend to die right after they appear.
In addition, algae has started to appear on the older leave of all plants. Specially on my sword and criptocorine plant older leaves. I would say that all the plants are not growing at all. New leaves are smaller in size and twisted.
I have been trying to isolate the problem. At first, I thought it was Ca deficiency as new leaves were distorted and smaller. So, I change RO to tap water mix to 25% RO and 75% tap water. No much of a change there after a month.
Started to add potassium as the older leave in the Amazon sword started to "melt away". It actually stopped that, but not new growth.
I have been reading and it seems to be Boron deficiency + lack of CO2 , but I am not quite sure. I might suspect that it is a micro nutrient deficiency and not macro as I initially thought.
Any ideas are really appreciated!!!
