κιεγω το εχω ακουσει αρκετες φορες,δε λεει κανεις οτι δεν ισχυειαπλα εγω προσωπικα προτιμω να μην το βαλω μεσα στο ενυδρειο

καποια ενδιαφεροντα αρθρα στο θεμα για αρχη, ειναι εδω

ενα κομματι, (αυτο που μπορεσα να βρω ευκολα δηλαδη)μιας ερευνας:

"Atlantic salmon were exposed to hydrogen peroxide (1.37–2.58 g l−1) over a range of temperatures (10.4–16.0 °C) simulating treatment for sea lice. Gill tissues and behaviour were monitored. Exposure to 2.58 g l−1 for 20 min caused total mortality (n = 1 while a shorter exposure, 10 min, at the same temperature caused only one mortality. Exposure to 1.37 g l−1 for 20 min at 10.4 °C caused no significant damage to gill tissues. There is a significant correlation (r = 0.895, F = 24.13, P < 0.01) between the level of exposure and the degree of gill damage."


μπορει το συγκεκριμενο κομματι να μην ειναι αντιπροσωπευτικο της ερευνας,δεν την διαβασα ολη,αλλα εχει ενδιαφερον.

"Are there any target animal safety concerns with use of hydrogen peroxide?

As with any aquaculture drug or chemical, improper use may potentially lead to ineffectiveness of treatment. Underdosing, toxicity from overdosing, and pathogen tolerance or resistance (the disease-causing organism may become tolerant or resistant to treatment) are some of the potential problems that could render treatment ineffective. Some species of fish have been shown to be very sensitive (see Are Any Species Sensitive to Hydrogen Peroxide? below). For species not listed on the 35% PEROX-AID label, test a small subset of fish before treating the entire diseased population. Species differences, differences in fish age and size, as well as differences in water quality parameters and other factors may alter hydrogen peroxide efficacy and fish toxicity.
Reduced growth rate has been reported in fish treated with high doses of hydrogen peroxide (Speare et al. 1999). In addition, damage to the gills has been reported in some species when hydrogen peroxide has been administered at high or lethal concentrations. For instance, at 22°C, there were 50% mortalities after 3 hours in channel catfish exposed to 238 mg/L and bluegill exposed to 460 mg/L (Rach et al. 1997; Speare et al. 1999). Rach et al. (1997) also noted that early life stages of rainbow trout, i.e., sac and swim-up fry, were much more tolerant of high concentrations of hydrogen peroxide (greater than 1132 mg/L) than larger, older fish. This may be due to differences in gill function and gill anatomy among fish of different ages and sizes.
Mansell et al. (2005) observed significant changes in several blood parameters (lactate, osmolality, and pH) in kingfish following hydrogen peroxide treatment, but overall, there were fewer changes after treatment than were observed during peak infection with the monogenean parasite being treated.
Are any species known to be sensitive to hydrogen peroxide?

Several species of fish are known to be sensitive to hydrogen peroxide, and the use of the chemical may be toxic to those species. 35% PEROX-AID is not recommended for use on northern pike or paddlefish and should be used with caution on walleye because these fish have been shown to be sensitive to the drug (35% PEROX-AID label).
Tolerances of different concentrations of hydrogen peroxide by five species of ornamental fish, representing five different families, were tested at 1 hour and 24 hours (Russo et al. 2007). Blue gourami (Trichogaster trichopterus) did not tolerate any of the concentrations tested for 1 hour (11.4–15.9 mg/L) or for 24 hours (3.3–6.0 mg/L). Likewise, the suckermouth catfish (Hypostomus plecostomus) did not tolerate even relatively low doses at 1 hour (6.6–21.9 mg/L); no tests were run on suckermouth catfish for 24 hours. Hydrogen peroxide at these concentrations may not be suitable for use in these two species; however, additional testing in different water quality conditions or in different types of systems is warranted.
By contrast, for 1-hour exposure times, serpae tetras (Hyphessobryconis eques) tolerated 17.0 mg/L; tiger barbs (Puntius tetrazona), 10.0 mg/L; and swordtails, 20.2 mg/L. For 24-hour exposure times, serpae tetras tolerated 5.6 mg/L; tiger barbs, 5.0 mg/L; and swordtails, 5.4 mg/L (Russo et al. 2007).
As a general rule, hydrogen peroxide should not be used for treatment in combination with other chemicals."


με μια πρωτη ματια φαινεται πως μπορει να χρησιμοποιηθει αφοβα,αν γινει με προσοχη και ξερουμε τι κανουμε. αποτι φαινεται την τοξικοτητα την επηρεαζουν αρκετοι παραγοντες οπως θερμοκρασια νερου(φαινεται να ειναι πιο τοξικο στις δικες μας "ψηλες" θερμοκρασιες),χρονος εκθεσης,ειδος ψαριου κλπ...

εγω εξακολουθω να μη θελω να το δοκιμασω μεσα στο ενυδρειο παντως
