planted 5.5g with c02 update (and 40g too)

i went out last night and picked up some sugar and yeast, and made myself a quick diy c02 system with enough supplies for 2 months for about 10$.

Overnight lots of oxygen bubbles have appeared on my plants, but im now worried about thread algae. it started about a week ago and i dont know what to do when it starts to get bad.

also, the mixture of c02 i used was a 3/4 bottle (2L) of water with 2 cups of sugar and 1 tsp of yeast for 5.5g. the tube goes directly into my filter intake and seems to dissolve the c02 fairly well, at one bubble every ~10 seconds. is this ok? too slow? too much? new to c02.

excuse the messy scape i had to seperate a few plants real quick and havent gotten around to fixing it up yet.




and my 40g




anyone have any input on c02 for small tanks and hair algae? the 5.5g has a betta, 2 guppies, 3 snails, and 2 ghost shrimp

Decrease the amount of time you keep the lights on. How are you diffusing the co2?

my lights usually stay on from 7:30 AM to around 10PM, is this too long? dont my plants need the light to use the c02?

I have the co2 tube going into the filter intake where its being munched up by the impeller. no bubbles are coming back out so i assume it is being dissolved alright.
