What do you mean "the co2 bottle ran out"? What kind of co2 are you running?
1 squirt of easy green a week isnt much. Ferts didnt cause this. Struggling plants did. You have to fix that moving forward
I wouldnt do the bleach thing, not in your case and not for this. Dont spray anything directly on plants out of the water, even excel or peroxide. Remember struggling plants is what got you here. The last thing you want to do is cause them more tissue damage trying to kill the algae.
You can spray peroxide or excel directly on the plants underwater, with the current off. Let it sit for 20-30 minutes and turn the filter back on. Careful with peroxide, wont take much to kill the bio cycle in a 10 gal. Ideally, esp with peroxide you would do a 50-60% water change right after the soak period. Excel you can be a little more liberal because its not such a threat to the cycle.
But really I wouldnt get too carried away with chemical treatments right here. This stuff you can manually remove fairly easy. Then a good cleaning, and getting the plants happy will take care of its "food"
Removing all the plants and giving the tank a good cleaning (without disrupting the bio cycle) is a very good idea. Do that. Manually remove whatever you can off the plants themselves. Then replant everything
That monte carlo, pick off 10-15 of the nice little green tips, the brand new fresh growth. Go back with only that and toss everything else.
Also good avdvice from vanostav on keeping any decaying leaves removed, and why you should. On that same note, all those reds in the front left, is that TCs converting? There's another big source of organic waste as the existing growth on those dies away during the conversion process. Nothing you can do about that, just know that its in the equation
You need to be extra viligant with cleaning and pruning, always but especially right now.. Cleaning means the filter and substrate surface. Pruning means removing any dead or dying leaves, old growth that gets in bad shape, all that sort of thing.
