got the factors causing the BGA under control, but theres still BGA in small spots around the tank. Read about dosing peroxide with syringe on spots, and it seems to work great! However theres leftover bits of BGA all around the moss covering this driftwood piece... Could i super dose a 5gallon bucket of water and dunk the driftwood in there? would my moss be okay? anyone have info on moss vs peroxide lol

Hope this helps...... This has been my experience and what I follow. So far no issues.
To spot dose in the tank with H2O2
Turn off filters
Fill syringe with 2 ml per total tank volume size* (not actually water). NEVER GO MORE THEN 2ML per Gal. You can start with less. BUT NEVER MORE THEN 2ML.
Direct a small amount directly on the algae underwater
Wait 15min
Do 50% water change
2hrs later turn filters back on
Wait 1 wk before additional spot dosing.
If you have snails or shrimps this could be a little harder on them Vs fish. But it has worked even with them.
The Protocol for doing a DIP With H2O2
There is 2 ways. Smaller amount with longer Dwell time in the dip
Or More concentrated amount with shorter time in the dip.
The First would be Smaller amount longer dwell time.
5ml of H202 to a gal of water. Soak plant or driftwood for 6 hours. Change water Rinse and return.
OR
Stronger amount and shorter dwell time.
10ML H2O2 to 1gal water and let it soak for 1 Hour and then change the water and flush. Let sit. Then return.
You can also try using a spray bottle with strait 3% H2O2. Doing this I would spray it. Let it set for 5 minutes then add a gallon of water let it sit for 1 hour and then change the water with fresh. Let it sit for an hour and then return.
Some of these protocals can be used together or to help cure a tank.
You could do spot dosing inside the tank, if that doesnt work you could go as far as doing the long or the short dip. BUT remove all your Fish, shrimps and snails from the tank put in another tank or place for time being. Drain the water from your BBA infested tank. Use the spray bottle with the strait 3% H2O2 and spray all plants, glass and substrate you can with a nice mist. Let sit 5 minutes fill tank. Let sit for one hour. Change the water. Let run for one more hour and re-add livestock. Should notice results with in the first few days to week.
It can also help before you treat any of it to also try and pluck it off first.
There is also a Bleach method that ive used as well that works well with many algae. In most cases depending on where my plants come from. I will bleach treat the plants before they go into my tank. It can also be done with H2O2.
Hope that helps feel free to shoot me any questions.
This wont help with BBA or Hair or several other algae. Only with Cynobacteria like green slime.
Whoo, it's good to know I read this one right and it was in fact cyano and not BBA.
That is correct. H2o2 won't help you with BGA. You need to try to remove it physically as much as you can and dose with emycin like cradelfan mentioned. I posted the H2o2 for use if needed. Bleach treatment will get rid of cyno as well. Sorry for the confusion.
thanks for the clarification constevens, I had never heard about H202 treating BGA either. I don't know why people mess with tough ways to treat BGA, Erythromycin is so easy to add and it kills it within a few days......Doesn't hurt the good bacteria in the tank and won't stress the fish, it's the best way if you can buy the medication.....
well the thing is, I have used Erythromycin, and it didnt get all the spots. There was still some hidden in my moss, and stuck on slate rock cave. I will be siphoning any clumps i see, scaping back glass wall and siphon the second it comes off. Dose the tank with Erythromycin again, but take out the cave and the wood pieces w/ moss and dip them in peroxide. And if any spots show up in my tank, do a spot treatment. And with my dosing of KNO3, the recovery of the BGA in my tank is very slow. Its just that i had too much left. Im trying to annihilate it completely.... Though im now questioning the health of my moss 
looks to be some dead strains mixed with new growth everywhere. It hasnt stopped improving though so who knows !
