View Full Version : BBA/Thread Algae

I got up this morning and looked into my tank and I could actually see the algae threads floating in the water! I did a 50% water change last night after pulling algae off of the plants and it literally grew back over night. I guess i had better do a 4 day black out. Will this lack of light bother my new fish? (how on earth will I be able to tell if they are alive?)

I am also experiencing the brush algea problem. I have been told by many that a blackout will not help. Instead, it was suggested to me to:
1. prune away any leaves that have the algea on them
2. scrape off algea from any equipment OR take out equipment (filters, heaters) and put them into a bleach solution to kill algea (rinse and put in water with declorinator before returning to tank)
3. do a 50% water change
4. add nutrients: KNO3, K2SO4, KH2PO4, trace (like maybe flourish)
5. be sure CO2 is at desired levels! This should actually come before the nutrients (check pH and KH against a chart -- there are many on the web)
6. add nutrients again 3-4 days later
7. do everything all over again the following week for 2-3 weeks
I have begun this plan just this past weekend and am seeing good results already!
Oh, just to answer your question about the blackout -- in my experience, I tried a blackout for 5 days to get rid of some green water a few years back. Worked like a charm as far as the water. I lost 2 fish though. I don't think it was due to the blackout though. They were already knocking on death's door. :( Usually, fish due just fine in blackouts.
GOOD LUCK!

A combination of the two will work better than either by themselves.
I had BBA before and it's tough. Here's what I did. I cut all heavily affected leaves off the plants and scrubbed any that was attached to the tank itself loose. There was even some growing on my heaters and filter parts(siphons, returns etc.). I dipped those affected parts in a solution 50/50 bleach/water. Then rinsed them well, and then put them in a bucket with fresh water with water conditioner in it before returning it to the tank. After re-assembling everything I did a 75% water change paying special attention to cleaning up any crap laying on the substrate. Disconnected CO2 and covered the tank with double layers of trash bags. Left it for 3 days. After 3 days another 75% water change and covered it up again for 2 more days. After those two days I did another 50% water change and started CO2 and ferts. Much of the BBA was either dead or gone when I uncovered the tank the second time. And getting the plants going with the CO2 and ferts was what kept it from returning. In a very short time I had zero BBA and haven't had a re-occurrence of the stuff.
The fish will be fine in the dark. I gave them a light feeding in between the two blackout periods, but it's not necessary.
If you have a spray bar raise it while in the blackout period.
This is also what convinced me to get some(TRUE) SAEs. They dine on BBA, but can't keep up with it when it's an epidemic. After it's controlled somewhat they will keep it in check.

Djlen, I had my CO2 and a part (as in wrong) broke. Fortunately I had not added any ferts yet. Any way, covered the tank in black bags, (I had done a pruning, cleaning, vacuuming last night) .
I also just got an ancistrus (bristlenose cat). Hopefully he will dine o.k. during the black out.
The fish will be fine. The algae will die off for the most part. Then it's up to you and keeping the water "clean" and fertilizing.
That crap is like the plague. Good luck!

Edit: What part did you break, and how did that happen?

It was a temp. part going from hose to needle valve. It just wouldn't stay on right. Clippard has sent me the part I need, I just haven't gotten it yet. Hopefully Monday it will be here, that will be about 4 days. Then I can clean, hook up CO2 add ferts and cross my fingers.
skittyfish -- I'm interested to see how the blackout works for you. Please let us know! thanks!

Well, after 4 1/2 days, the algae "appears" dead. I lost 3 Cardinal Tetras and am missing a clown loach (cannot find the loach anywhere) and am also missing 2-3 pygmy cories.
Anyway, I did a 50% water change, massive pruning and pulling on leaves. Changed my prefilter. So far so good.
Now if the UPS man would just show up with my CO2 part then I will be in business. I don't want to add any ferts until I get my CO2 up and running. I'll let you know how it goes.

Yahoo! All algae is gone. I got my part, CO2 is going, got my Duetto, so it is acting as a reactor. pH is 6.6 kh is 2.8 d/kh or 50ppm. NO3 >5 i am trying to get it up (I missed the spoon and spilled it into the tank. Waiting a while to see what happens)
PO4 is .25 and Iron is .25. Temp is 79 F.
NO ALGAE.
I put some new pic in my album, have a look. I have some plants that I don't know the name of. If you know please let me know.:D :D :D

Did you find your missing fish? I've had my clowns dissappear before and swore that they had taken "Darwin's leap" to have them pop up from nowhere...usually around feeding time ;)

Well, I have come to the conclusion I only had 4 Loaches (hard to remember what I have and have had) and my pygmy cories did show up. I never did find the rest of the cardinals, about 3 are actually missing, I think maybe they died and the rest of the fish who had not been fed for four days took advantage of the meat (gag).
Anyway now I have to decide what fish I want to go in this tank. Maybe some kribs, I don't know, I haven't had much luck with appistogramma's or even Angel fish. Any ideas will be welcome.
