Blue Green Algae

My tank 55gal has bad case blue green algae. My house smells like pond. I dose everyday using PPS. The problem was caused from low water circulation from using a reactor on my fluval 305. I have switched back to a difusser and the filter is working as good as new. Should I continue to dose? Should I do water change? Please help.

I had a a pretty nasty case of BGA when I originally set up my tank. You can see how I treated it here:

"at the start of Week 3 I got a huge bloom of blue-green algae (aka as cyanobacteria). The whole tank was covered within a few days. I have no pics from this period because it was frankly depressing and I almost quit the whole planted tank thing. I decided to tackle it as aggressively as I could, and because I had no fish in my tank and the filter had not cycled yet, I could afford to take somewhat more extreme measures than if you had to worry about the fish or the nitrifying bacteria. So here's what I did, which ultimately worked very well, so others may want to try it. It was adapted from the One-Two Punch Whole Tank Treatment:

https://www.plantedtank.net/forums/23...atment-21.html

But I was even more aggressive. First, I started with a water change, in which I tried to remove as much of the BGA as possible by hand (it tends to come off in sheets). While the water was low I also spot treated the hardscape with 3% H2O2. Then I refilled the water and dosed both H2O2 AND an Excel overdose. I let it rest for one day and then started a full treatment with Erythromycin, including water changes every other day. On the water change days, I repeated the H2O2 and Excel treatments and continued removing by hand. By Day 3 the difference was remarkable and by Day 6, the tank was spotless. Yes, this was aggressive. Yes, it was probably overkill, but it worked. At this point I also learned that i had made a key rookie mistake. My light periods had been for almost 12 hours straight thru. So I lowered my light period to 8 hours split into two 4 hours sessions and added a daily capful of Excel to my maintenance regiment, and algae has been (mostly, though not entirely) under control since then."

It worked for me.

As others have noted, I also highly suggest lowering your photo period to 7 to 8 hours a day in two sessions with a break in between.

Stop dosing traces.

I have also been fighting BGA, have done extensive research on it and how to prevent it. I have not seen anything about trace dosing being a inhibitor of BGA growth, do you know this from experience?

If you don't have shrimp, this is the one that I used in the past. Used it once and BGA never came back.

Chet, if you put hydrogen peroxide in a spray bottle and spray the algae that is exposed when doing a water change it will kill it. However if you don't fix the root problem, or BGA growth inhibitor which I have read to be excess NO3, mulm, and flow, the BGA will just regrow and your efforts will be futile.

Cyanobacteria requires some of the nutrients to grow. If there's excess, it will take advantage of it, especially iron.

Any reference or experiment that shows that increased iron induces BGA bloom ?

I asked you in the other thread on cyanobacteria and you did not answer. Is cyanobacteria another sign of trace toxicity ? If we stop dosing traces will the cyanobacteria stop growing and die ? What level of iron and what ratio to other nutrients induces cyanobacteria ?

@Chet Don't worry about traces, this guy writes that sentence on any thread showing problems. He previously said traces kill algae because they are so toxic...

Are you using PPS or PPS- Pro ? Do you add PO4 ? Maybe you are lean on NO3, could you test if they are above 10ppm ? I would increase NO3 as a first step.
Low NO3 could have induced BGA, but increasing it does not cure it. I use erythromycin for that. There are other methods, this worked for me.


Remove all the algae you can .

"Add 2.5 mg/L erythromycin. If you have a protein
skimmer, turn it off. I believe it will inactive a lot of the
antibiotic through coprecipitation with protein. It will,
however, be very usefull later.

Day 2.
Add 2.5 mg/L erythromycin.

Day 3.
Now you should see a lot of dead blue-green bacteria
floating around in the tank. Increase filtration (a second
mechanical filter if possible) to get rid of it. If you have a
protein skimmer, turn it on. The critical thing now is to get
rid of as much protein (dead bacteria) as possible to avoid a
peak of ammonia.

Day 4.
Most blue-green bacteria should be dead by now. Try to
clean out as much as possible of the dead stuff. I use a jet
stream of water from the outlet of a canister filter to remove
it from plants and decorations. Combined with the second
mechanical filter, this works fine for me. Let the filter work
for a couple of hours then make a 50% water change. Add 2.5
mg/L erythromycin.

Day 5-7.
Wash the mechanical filter at least once a day. Keep
check on ammonia and nitrite but do not change any water
unless absolutely necessary. The extra filter can be removed
as soon as the water clears up.

Day 8.
Make a 30% water change. Add 1 mg/L erythromycin.

From now on, resume your normal maintenance."
