Hydrogen Peroxide Dosing

[sairving]

I've been having issues with cyanobacteria for the last few weeks in my 10 gallon tank. The last time I had a problem, I turned the filter off for an hour and dosed the tank with hydrogen peroxide. It took care of the problem after a few days. 

Only difference is, I didn't have a nerite snail. Now that I have a nerite, I really don't want to kill her. Should I remove my snail and treat like I normally would? Would a lower dose of peroxide work and not cause harm? 

I really don't want to use antibiotics.

I've never treated a tank with H2O2 for cyano. Glad to hear it helps!

I'd probably try to remove as much simply by hand / with instrument first. Then lightly dose.

At the core, there is some sort of imbalance: maybe too much light -- intensity or photoperiod; perhaps too much "fuel" for cyano to grow (e.g. overfeeding); also possibly too little flow. Cyano appears in several tanks of mine following a period of insufficient maintenance or out-of-balance factors. Once it appears, it is very difficult to completely eradicate.

My tank is definitely out of balance right now. I need to mix up a new batch of liquid ferts. Might be time to tweak things a bit. The lighting intensity has been cut back and I've been doing extra maintenance. Its slowed the cyano growth down. I have some flow in the tank (enough to not bother my betta) from the HOB and sponge filter. Maybe s the mopani wood is blocking the flow in a few places. 

H202 is probably the slow way to kill cyano. I've found you have to treat the tank for 3-4 days. The hardest part is remembering to turn the filter back on.  Oops

I would remove your nerite for dosing. H2o2 is crazy lethal to snails. It causes them to foam and melt instantaneously . Sadly I know this trying out peroxide dips on plants and losing bladder snails.
