Trace elements and bba algae?
I'm starting to see bba algae a bit more than I expect to. I don't think its the light or the CO2, but maybe it could be the excessive trace elements?
My parameters are:
Size 75 gallon community tank
Lighting Aquaticlife T5HO 2 bulb, 1 x 6000k bulb, 1 x 650mn bulb, On for 10 hours per day
Equipment Eshopps WC-100 sump, Supreme Mag-Drive 7 pump, 300w heater, Aquatop UV lamp
CO2 DIY System @ 1.5-2.5bps, 2 x 1 gallon jugs, Pump intake diffusion method
Substrate Styrofoam landscape, 1 - 1.5" of potting soil, 1 - 1.5" of gravel
Parameters 81 Degrees, 0.0 Ammonia, 0.0 Nitrate, 0.0 Nitrite, GH 10, KH 10, 7.0 PH
Fertilization Seachem Flourish tabs every 3 months, Seachem Flourish Excel every day, Seachem Flourish twice a week, Liquid iron once a week
Taking into consideration that:
1. my tap water has minerals in it
2. the fish food has minerals in it
3. I'm overstocked so there's plenty of fish waste
4. I don't vacumm so there is some mulm here and there
5. I change 50% of the water weekly
So my question is: Do I need to keep dosing the liquid iron and the Seachem Flourish trace elements? I think I am going to stop and see what happens. I am due for another round of Seachem Flourish substrate tabs but I think I will hold off on that too. Most of my roots have reached the dirt portion of my substrate anyway. Can excessive trace elements contribute to the noticeable growth of bba on the edges of leaves and exposed roots? I will continue using the Flourish Excel.
