Sooo... you must have been, what , 15 when you wrote that.:D

Talked to a guy at the ag extension office...

H2O2 is approved for various 'finned fish' applications, I think one of the links I gave has roughly the same information. I know Biollante uses H2O2 on fingerlings prior to quarentine for his tasty critters aquaculture.

ag guy said 'he thought maxium long tem dose was 120 or 130 ppm" but remember this is for 'finned fish'.

H2O2 is more potent than chlorine bleach, higher oxidation, so in a sense perhaps more dangerous, though H2O2 is less ‘persistant and easily removed or broken down by agitation/aeration.

Sodium percarbonate is popular and used for ponds,m good for removig n algae off rocks etc.

Turns to H2O2.
Used in ponds, laundry etc.

Not real good for aquariums though.

Hi,

I am on my second day treatment with h2o2 (2ml/g), the bba it's turning pink and most of it is almost gone but, I got a little ammonia spike (0.15). I also used Metricide 14 for the last 6 months. I should also mention that yesterday I did a 70% wc and change all the mechanical media in my filters. Goldies and plants are OK. Should I do a small wc or leave it like this until my next weekly wc ? These are 1.5 years old well established tanks. All the other water parameters are OK.

edit
Sorry, I also changed the bio media (Eheim Substrat Pro). I am just wondering if h2o2 can affect the healthy bacteria.

Hi,

I think that forgetting these products is the best you can do. Quiet any tank can be recovered curing the root cause, without redoing the tank

Despite the last photo is not a close up, I can promise you there's no algae trace and I have some closeups of all plants in this photo posted in another topic here

Most plants are the same, only pruned to accelerate the algae battle.

Hi jonny_ftm ,

My wife would like to know the name of the red plant in the mid ground and the brownish one in the back ground right corner. Thanks.

I tried it for some vals instead of the Excel.
Worked well as logn as you are careful and not think more is better.

Just let it do its thing and kill the algae slowly over time.
