kemija za ubijanje algi??

[Karlo]

Ekipa da li ste koristili kakav učinkovit kemijski algae killer? Imam jedan lavor pun microsoruma i bolbitisa umotanih u končastu algu pa bih je rado uništio.

[cann]

kaj ne probaš sa peroksidom, kad ih imaš u škafu 

[Karlo]

radije bih nešto komercijalno, peroksid je potencijalno opasan i za bilje. jednom sam varikinom (otopinom) pobio hrpu anubijasa

[cann]

ok, al ak ga smiksaš 3%-tnog ne vjerujem da bi spržio bilje
kaj ne probaš neš malo ? i nekak ne vjerujem tim algocidima kupljenim 

[Karlo]

a mogao bih polovicu odvojit i probat, kolko dugo se namače s peroksidom?

[cann]

čitao sam da u tanku do 10 minuta, bez filtracije, probaj smanjit na 5..nisam probavao, al pošto sad imam "veliki" biljni, i ako ću popušit tak neš onda ću prvo to probat..čuj ak ne sprži rane 3%-tni, onda neće ni bilje

[Karlo]

budem probao s tim, a drugu polovicu bi s komercijalnom kemijetinom. Ima tko isprobano rješenje?

[pravda]

Kod sebe sam primjetio na mahovini koju ošišam i stavljam u teglu na prozoru da nakon par dana nestane zelena končasta kao da je i nije bilo,pa možda da koji dan ostaviš to sve u lavoru za probu?!?Znači čista pipovača drito iz pipe sa klorom.

ja sam pokusao sa TETRA ALGIZIT-om,,,,,rezultat.....nula

Ak' ti je bilje još u lavoru, poslušaj Cannibala.  Peroksid uništava alge u maloj koncentraciji, microsorum bi ti mogao mrvicu posvijetliti. Ništa te ne košta da malo staviš u taj lavor s biljem, nije da stavljaš u akvarij. Končastu sam užicala za koze jer ju obožavaju i kuglica je nestala u roku od 4 dana. Možeš pokušati i s njima ako bilje odlučiš staviti takvo kakvo je ravno u akvarij.

Ovdje ima nešto o peroksidu- iz prakse (ne moje):

Algae and plants both produce low levels of peroxide and superoxide as a
aside to normal photosynthesis, and they have the enzymes necessary to
protect themselves from its effects.  The enzymes are internal.  I don't
believe that they express the enzymes externally and so don't use them to
protect the outer cell membrane.  In fact, I wonder if the enzyme may be
protective only within the chloroplasts where the peroxide and superoxide
are produced..

This would explain the dramatic effect of rather low concentration of
>H2O2 -- 2 oz of 3% H2O2 in 10 gal. = 0.005% H2O2.

Because the syringe is used for spot treatment....  the localized
concentration is a lot closer to 3%...at least for the first few seconds.
This also restricts the damaging effects to a portion of the tank. By the
time the H2O2 disperses to the full aquarium, it may no longer be "H2O2."
Perhaps only the localized populations of organism X would be killed ...
because the tank should be full of them, their relatives would survive.
***
In summary:

- - Hydrogen peroxide is an effective treatment for cynobacteria
   with little affect on plants.

- - As for the amount used, 4 oz per 35 gallon (minus substrate)
   spot treatment is already effective.  That's roughly 2 oz per
  15 gallon.

- - There doesn't seem to be an effective and safe dosage level
   for snails and shrimps, and possiblely for fish.

***
Some people add one pint of 3% hydrogen peroxide per 1000 gallons. This is said to not have any significant impact on plants or fish and is reported to work well on both suspended and string algae. The only potential problem is that if you have massive amounts of string algae you may create a very large oxygen demand so physically remove as much as possible before trying this method - this caution cannot be over emphasized. It may be necessary to have an aerator ready to put in the water or, for small ponds, it might be better to remove some of the water and the fish to a temporary holding tank until the dissolved oxygen returns to safe levels. Adding hydrogen peroxide, while effective in removing algae, will essentially result in re-dissolving the nutrients which contributed to the algae growth in the first place.

znao sam, tnx na tekstu

Nema na čem', kemičaru.

Imao sam problem sa končastom   i nakon mjesec dana "borbe" sam ju drastično smanjio i sad je imam u tragovima.
na jednom susjednom forumu (ne znam da li smijem napisat koji), sam našao post kako su ljudi sredili beštiju
dodajem već 4 dana K2SO4 i smanjila mi se za 80%.
tamo sam pročitao da se dodaje na vrh žličice svaki dan ,5 dana i nakon 5 dana izmjena 30-50% vode.
Ja sam smiksao po PPS Pro (pošto tako gnojim i ostalo),i dodajem 1ppm dnevno.
Negdje sam dalje zakučio da Kalij pospješuje apsorpciju Fe koja je okidač za končastu .
Odmah sam se bacio na traženje K2So4 i u roku pola sata na akvarij.net-u našao spomenuti spoj (hvala Veco )
nije skup a nemaš šta loše napravit  

[Karlo]

radi se o lavoru, a ne o akvariju
k2so4 inače standardno dodajem sa ostalim makroelementima, a Fe nije okidač za končastu
