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.

I see your nitrates are zero. Do you have fish In your tank?

After reading the tread it sounds like fluctuating CO2 levels could be the culprit. That and my water flow. Tuesday night is mad chemist night when I make a new batch of yeast/sugar and swap out the oldest gallon jug. I've noticed the bps is a bit slower than it is on Wednesday when the new batch is going strong. I'll probably go pressurized later this year sometime. I guess I'll leave my fert regiment alone since my plants are doing well.

I'm in the same tank, so to speak.

My BBA grows only on the plastic stuff, though. Odd. I dose CSM+B and have water hard enough to cut with a knife.

I had 0 nitrate until I started dosing KNO3. Now I run about 20 or so.

I have little doubt your BBA is from the CO2 setup. It's certainly not from too much traces. Many other algae problems are caused from low nutrients. With a nitrate of 0 your plants are not going to do well regarless of perfect lighting or CO2. You would see far better results dosing a complete supplement of dry fertilizers and doing away with the DIY CO2. Just supplying all the proper nutrients will increase plant health tremdously. Keeping the DIY CO2 is a personal choice. Many have been succesful with it's use. I have not. My opinion on high tech versus low tech is simple. Either use quality lighting and CO2 injection or stay low tech. Things happen much slower with low tech and much fater with high tech. It's kind of like either driving very fast or slow in traffic. When something happens at high speeds it happens fast without time to avoid disaster. DIY CO2 is like driving fast while texting, something is going to happen eventually.

What's the easiest, cheapest, and most effective method? I've been doing a little research but now my head is just spinning. Where do you buy this stuff?

2.5 bps if awefully low for that large volume of water especially with a sump and overflow box....

I like supporting the locals here on TPT. Nilocg seems to be the go to guy here for ferts. Otherwise, greenleafaquariums.com or aquariumfertilizer.com

Hey Blaz, what kind of bubble counter and diffuser do you use? Do you have any pics of your CO2 setup? My globe stays green all the time.

NM - I checked your profile.

its fine, but green doesn't always mean GO
in this case, BBA is a clear indicator of 1 of things
too much light
too long of photoperiod
not enough co2
or not consistent co2

those are the 4 driving factor s for BBA
