Γεια σου φιλε ,
One Two Punch και καθαρισες !!!
Το εχω κανει πολλες φορες χωρις κανενα προβλημα....
Φυσικα καποια στιγμη πρεπει να βρεις και την αιτια της αλγης!
Διαβασε προσεκτικα....
FIRST PUNCH: H2O2
Whole tank H2O2 treatments don't get much attention. The results are typically very poor, at least until you get into such doses that fauna are at risk; and after a few failed attempts, most folks understandably write this option off.
But the truth is, most people perform this treatment completely wrong.
The RIGHT Way:
As I said before, Concentration * Flow * Time.
So if you want an effective treatment, provide massive flow during the entire treatment period. Since flow is constant through fish gills, to protect them you shorten the time, by wasting none of it with periods where the algae isn't affected, and correctly terminating the treatment. If this is done, the increase in safety is actually enough that concentration can be increased.
First, prepare the tank. You want as much flow as possible. If you have extra powerheads, add them. If your sole source of flow is your filters, you'll have to temporarily remove the filter media to a bucket of tank water, and leave the filters on. Otherwise, this is optional but still beneficial. I have a cheap Koralia clone that with 1,320GPH flow, turned out to be too much for any of my tanks; but I keep it around because it's ideal for this treatment.
If you have Marimo balls, temporarily remove them to a bucket of tank water as well. Cladophora is very hardy, and normally not affected by whole tank H2O2 treatments. But this treatment can burn them badly, especially on sides exposed to direct flow. If they're also infested with undesirable algae, they can be treated simply by keeping them in the bucket in a dark place for a week. They can tolerate extremely long blackouts without harm, unlike other algae.
Keep the lights on. Light has no effect on the H2O2, only your ability to see what's going on.
Now add 3% H2O2, at a dosage of 4 tbsp. per 10G of actual tank water volume (excluding substrate, plants, etc). Yes, that's double what's typically used; as explained previously we can use a higher concentration.
Allow to circulate for 15 minutes. During this time, redirect flow a few times if possible, to make sure all areas get covered. If you have particular trouble spots, try to ensure they get direct flow during part of the treatment.
Now terminate the treatment. Do a 50% water change, or more if you know it's well tolerated. Return the tank to its normal configuration, including replacing filter media if it was removed.
Less hardy algae may be effectively killed by this alone, especially if flow was good. But all algae will be weakened, and now it's time for:
SECOND PUNCH: EXCEL
Any remaining algae not killed by the H2O2 is now extremely susceptible to Excel.
If you weren't already using Excel, or were using it at the recommended dose, add Seachem's recommended initial dose of 5ml per 10G. No further large doses are necessary in this case. Algae builds up some tolerance to Excel, similar to sensitive plants like Vals. In this case, the H2O2 treatment followed by a single, sudden Excel spike is enough to quickly finish algae off.
If you were already using Excel overdoses, continue using the previous dose.
Enjoy your algae-free tank. If there are any underlying problems that caused the algae outbreak in the first place, correct them so your tank stays algae-free. In some cases, a thorough algae removal like this is enough to improve plant health to the point where algae will not return.
