Alright, allow me to explain and... thank you for the hijacking comment
. I mean they weren't using it anymore and I didn't see the need to start another one when I could dust this perfect thread off right here.
I have a problem with bba but it is a problem that persists. I will only allow the tank to get so bad before I tear it down, bleach it, and replant everything. I have heard the same, what I consider truth, story over and over regarding each type of algae. Bottom line, there is something out of whack be it lighting, ferts, or Co2. Let me give my tank bio and we'll see if the experts can give me a hand.
My lighting is a true story of live and learn. I had 60 watts of T8 6500 over my 125g tank and I couldn't grow anything. It is a 125 long and given the depth of my substrate I got about 19" of water that my lighting has to penetrate. Tired of having plants wither away I bought a light fixture that I knew would grow plant life -- a 6 x 80W T5HO light fixture... thats right baby 480 watts of luminescent heaven. Now on top of buying the equivelant of a rectangular search light I also put it approximately 4" above my tank. So in short... I grew plants alright and everything else too. There wasn't a type of algae that I didn't have so I took some steps:
Following this thread
I thought I would put Hoppy's theory into practice mostly because I don't have a PAR meter and I trust the work that this man does and here is the result:
First off here is a shot of only 4 of the lights on, 2 x 6500 and 2 x 10000 and this is what we can get. See the glare and the obvious over intensification of the lighting due to both light strength AND placement of the fixture. Notice my home made screens on display above the tank.
I know someone wants to comment on how sparsely the tank is planted but I assure you there is a plant at least every 2 sq. inches. After my last bleaching because of bba I had to mow a lot of leaves off of my stem plants to trigger new growth and that is what you're looking at right here.
Now, this is after I turned another light off. So I'm running on 2 x 6500 and 1 10K bulb AND I have the screens in place:
I have yet to find a location locally that sells the raw material that I need to dose dry ferts, lord knows that I would love to. I guess I could buy them online but unfortunately I am my worst enemy here because I don't want to take the time to learn a schedule that works for the tank. However, I do fertilize my tank daily with a blend purchased here
. I do dose religiously and I do a 50% change at the end of each week which besides providing the reset I believe my fish & inverts really enjoy the large infusion of fresh water. I dose according to their directions but I will admit that as the plants get larger my dosage gets larger because I suspect the amount dosed should mirror what the surface area of each plant can absorb... I could be wrong on this.
I have my fast growing stems, floaters, heavy root, and so on and so forth. Most improtantly is that the tank is PLANTED. Not semi or moderately but heavily. I will admit that the photos don't show to what degree the tank is planted so I snapped a couple more shots:
My struggling carpet
My giant vals are sprouting daughters and growing, excuse the Crinum thaianums I just picked those up today
My ball of java moss that I call shrimp manor is actually moss completely covering some mopani, the side is hygro and mermaid
Sprouting nana, I think
The point is that she is well planted and the plants are absorbing what I am giving them, the light is turned down, Co2 is high so what else could I possibly change in order stop bba from growing? Do I need to wait until the majority of my plants are larger and therefore can produce a larger uptake of nutrients and ultimately knocking bba down?
