BBA Getting Worse

I am thinking about increasing my CO2 bubble rate.

This is a last resort option for me.

Some members might remember when I gassed, and killed a couple of Discus, we had for years. I was careful, and turned up the gas slowly while observing the fish. At no time did they gasp at the surface for air. In fact they went to the bottom of the tank. I did not realize they were affected until it was too late. Also I thought due to their size, they would survive better. (Like people and canaries.) Besides the financial loss, the sentimental loss was even greater.

After that experience, I have not raised the CO2, and in fact I swore, I would sacrifice the plants before the Discus. So here we are, with BBA on most plants and ornaments, creating a "dingy" look to the tank.(Of course the fish look great.)

I have taken steps in the past, to overcome the tanks problems. Dual CO2 Rhinox 5000 glass Diffusers; over filtration ( 884 gph), and over circulation (884 gph+ Korila 2); and reduced photoperiod (8hr. X 130 watts).

So, What I am interested in doing is coming up with a "game plan", while minimizing the risk, to the remaining Discus of over gassing, to combat BBA by getting the proper levels of CO2. ( I do believe that is my problem.)

Logically, I think my first question would be where is the best place to purchase clinical grade 4 degree water. I have always made my own, and never noticed any drastic change in color during my last nightmare, till it was too late. (The solution of BB turned yellow in front of the white post in the Oracle d/c, but the rest of the solution did not seem to change, perhaps due to the blue tank background. I was expecting all the solution would of turned bright yellow.) Live, learn, and pay for it! :(:(:(

Rock,

I seem to remember purchasing 4 dh water from a plant or on line retailer. I will look around for it.

You may want to try the following when/if you raise the c02.

Add more surface agitation. Yes this may cause you to use more c02 but is much safer for the fish.

I did this recently and have noticed that my cardinals are much more front and center and active during c02 hours than before. I have not adjusted the c02 at all. No advers affects 4 weeks later.

Do some more water changes if you can and prune heavily any badly infested leaves. Better to prune too much than too little. The new growth can be used as a guage to determine the overall tank conditions.

Good luck!

Maybe it's already a past station for you, but you could use Excel, even when you are using CO2. It may compensate for any CO2 difficiency and work against the BBA without the need to increase the bubble rate. I mean to recall that discus can stand around 40 ppm, so that's walking a very thin line since an increase of 0.1 pH is already around 10 ppm. Only a pH controller can be that accurate (most of the time ;). Better stay safe and use Excel continiously.

thanks for the input.

I have been Excelling the BBA..........about 30mls a week, along with the co2.

Thanks, Gerald.

Just fried my pc hard drive.................so my world is really rocked now...........lol

I used Excel to try and fix some BBA issues without overdosing, it did nothing, after I adjusted the CO2, the BBA started falling off and plants grew better etc.
I'm not sure the issue of CO2/Carbon demand is the real reason why Excel helps, rather, more toxic effect directly.

CO2 on the other hand seems to have a different effect, it's not toxic I would speculate.

Still, long term stability and ease, getting rid of BBA, is still a CO2 issue.
