BBA in shrimp tank. Can not figure it out.

First, because I know you'll need to know this to help me out. here are my perameters:
Ph: 5.5~6
Ammonia: 0
Nitrite: 0
Nitrate: 5ppm~15ppm (? I think? The color matching test for this is always a pain in the butt for me.)
Kh: 0°~1°
Gh: 4°~5°
Tds: today-141. It is always kept between 125 at the lowest after water change, and 145 at the highest at weeks end before water change.

CO2 on 7:00A.M.-7:00P.M.

Light is: finnex planted 24/7 HLC. Here are the times on and power
6am W:0% R:0% G:0% B:0%
9am W:30% R:30% G:30% B:30%
12pm W:50% R:50% G:50% B:50%
3pm W:40% R40% G:40% B:40%
6pm W:10% R:0% G:10% B:30%
9pm W:0% R:0% G:0% B:0%
12pm W:0% R:0% G:0% B:0%
3am W:0% R:0% G:0% B:0%

I do my water changes once a week of about 10%-15%.

So, my issue I'm having is BBA. I've had other issues with different types of algae over the years, but have been able to figure it out, with help. But no matter what, I still keep having little BBA outbreaks.
This, and a few plants just won't grow, and simply die. Namely, I cannot get Aciotis acuminifolia to stay alive.
The only things I can think of is; gaseous exchange is off, too little or too much not sure. Maybe I'm not cleaning my monte carlo carpet well enough? I have definite worries of accidently sucking up baby shrimp. Or, maybe it could be im not cleaning my filter and filter lines frequently enough? I try to go by eye on this one.

Any other info you would need to help me out, let me know. I appreciate the help.

Any help? I know there are 1,000,000 bba threads, but any ideas? I want to fix the problem, not just get rid of it.

So, does anyone have any ideas? I know I posted this awhile ago, and I've gotten some under control, but any extra help would be appreciated!

The fix is somewhere in the light/organic waste numbers. If you don't have a heavily planted tank the odds are waste is decomposing, releasing ammonia/toxins and fueling the BBA. Are you dosing or is the nitrate naturally occurring? What size tank is it?

Truth is, nobody knows.

Try bigger water changes. At least 50% seems to have a better impact on plant health

There is an excellent 45 page thread with 449 posts written by experienced aquarists trying to link BBA to dissolved organic compounds by analyzing the concentration of Total organic carbon TOC. Unfortunately there was no correlation found.

The fact of the matter is that one remedy helps someone but the exact opposite helps someone else.

I could not agree more on big water changes helping plant growth, could not disagree more on big water changes being a good thing in a shrimp tank. I have two high tech shrimp tanks currently, and will never say it can't be done but WRoD is almost entirely a large parameter change issue in my view. It's a tough balance.

I agree with @Edward that I can find no direct cause. Among my 12 current tanks, the 2 that get BBA make no sense at all. I can move a Buce covered with it from one tank to another without BBA growth and it dies off in a week or two. I can only state with any certainly that it hates being sprayed with peroxide, but comes right back if you put it in the tank it has conditions to grow in, and doesn't elsewhere. Maddening algae.

My BBA theory is linked more to the development of periphyton. There is also an excellent thread started by experienced @Deanna describing biofilm and periphyton. Also I agree with niko from APC who talks here about having all the technology today but still struggling with BBA. He says we need to return to the basics we used to have decades ago, the time when we had not heard of BBA. Perhaps we are missing the right beneficial bacteria.

It's worth noting that one of the reasons why disinfectant glutaraldehyde Excel, large water changes and use of dechlorinators affect BBA is because they cause changes to periphyton. I believe BBA spores need the right periphyton composition as a substrate for further development.

People struggle with BBA under lights between 30 and 300 PAR, that’s very low to very high intensities. People also struggle with BBA when they do little water changes and also when changing 90% water daily.

So please enlighten us , what is the light/organic golden ratio?

This treatment wiped out all bba, and string algae from my shrimp tanks. Give it a try. Also, cleaning up all organic waste and matter in the tank is a good tip.

What helped me get BBA under control after a rescape was toning down my lights and doing a very thorough cleaning of my filter and tank. Removing all the dead leaves, dying leaves, and floating leaves. Increasing the plant mass goes a long way too. Making sure co2 is consistent and you're saturating the water well.

Once it became obvious the BBA was no longer spreading, I added in an SAE to eat what was there (without manual removal or killing it with chemicals, BBA will stay there forever even if it's no longer spreading).

This formula has worked for me. Some people say to turn up the flow, but that's never worked for me. I had BBA on my spray bar output holes so it clearly didn't mind a lot of water movement.

Now that it's been beaten back and isn't reappearing, I've been able to turn the light intensity up a little. Only time will tell but so far so good. Hope this helps you.

That's usually the case for most folks, unless you live in an alternate aquarium universe where no water changes, high light, heavy fish load, low plant mass and accumulation of organics has no effect on whether BBA or any algae will grow. On my 3-foot long I removed the Bolbitis which accounted for probably 75% of the plant mass. For the first time I started to see a few tuffs of BBA. Increased water changes, put fresh carbon in the filter and decreased peak lighting and duration a bit and the BBA was gone.

There's a host of things you could do, the more the better, each one has the effect of removing organics or increasing uptake of waste. Redundancy is king.

A lot of the times, returning to the basics is better than looking for a complicated solution. ;-)

Eric
how long did it take the BBA to go South after the application?
