Not eating

[Sols]

Hi all, I just redecorated my tank 4 days ago. I took out the drift wood and added 2 pcs of rocks instead. The ph levell dropped form 6.5 to 4.5. Is it alright?? I guess its good for the plants as they already started bubbling and growing. However, my fishes(mainly tetras) are not eating. They use to eat alot. Then i starved them for one day and now they throw tantrums at me, simply wont eat. Any suggestions???
And is there a way to control DIY CO2? I hooked it up with a reactor, the three ball type, but when the discharge is too much, the balls stop rolling.
Any suggestions??[] [] []

Sols,

Tetras tend not to be fussy eaters... they eat when theres food. I seriously doubt they are throwing a "tantrum". If they are not eating, look to other reasons... are they sick? are your water conditions poor?

Also, I'm moving this to the fishkeeping section.
