What is a recommended dose for a 120g

What is a recommended dose for a 120g

Typically, 1 mL per 10 gallons, but on healthy, established systems, the dose can be much higher. I've dosed as high at 1 mL per 2 gallons with no ill effects.

It's about 3oz but the cyano in question, rose to the top. I'm waiting for color change. I added 3ml of housegrade hydrogen peroxide

I did this test over the weekend and my results look just like your picture. The water is still clear and there is no pink or any color at all. Some pieces are clumped together and some are not. They are floating on top. So what does that mean? Do I have Cyano or Spirulina?

My water did have a slight pink tint to it. Not much tho. Last night I chalked my phosphate, it was at .02 using the Hanna Checker Hi, and nitrate was 5, so today I am doing a 20 gallon water change. It will help, but it's not resolving the problem. How can we fix this before I get too upset!. Lol

Easy test is to get some so called cyano out your tank and put it in a clear cup.
Add 3ml of Ho2o to that and swirl for a few seconds
Let it stand overnight, if color change on the red stuff we talking cyano if not its spirulina.

It turned green. That means it Spirulina. How do I treat for that?

For spirulina I used chemiclean successfully.

Its looks like cyano. Cyano in h202 turns green and bleeds the red into the water making it look pink.

 

[Mpierce]

Spirulina in h202 will do basically nothing, just stays red and doesn't change the color of the water.

@Lowefx, what did you end up deciding to do?

 

[Lowefx]

@jsker I dosed h202 for 2 days, appears that the cyano was getting worse, so I did a 20g waterchange and sucked most of it out. I'm going heavy on kz cyanoclean for a few days. I may revisit h202 in the future. I read that to much h202 can burn the gills of the fish.
It's an ongoing process, and I will continue to post here.

My water stayed clear and the clumps turned green. No pink or red whatsoever. That means spirulina.

I think it does, but I'm no expert and have never experienced it before.....
Can anyone else confirm that?

It is hydrogen peroxide, like from drugstore. and it is h2o2

Drug store is 03%. I believe food grade is a much higher concentrated percentage.

 

[jenreefer]

drugstore 3% works just fine

Does UV break down peroxide?

 

[Lowefx]

So I am stepping away from the h202, but I'm going to do weekly water changes and the last 2 days I've been dosing 20 drops of cyano clean. I don't know if this is good or bad (double the dosage), but I'm giving it a try.

Peroxide won't kill all of the good bacteria, but it will kick the cr@p out of cyano. Start slowly and give it a try. If it's truly cyano, you'll results in 2-4 days.

How does one treat cyano with h202? What level strength do I need? Do I just use a turkey Baster and shoot it at it? Could I just dip some rocks in a solution of peroxide?

Some people spot treat, I just dumped it into the overflow. You use standard 3% peroxide from the pharmacy. Start at 1 mL per 10 gallons and see how that works.

May have been spirulina all along.
