Maintaining a neutral PH

[illusion54]

I just recently put some bulbs in my tank and they are growing at a nice pace but i decided to do a DIY co2 injection for the plants to help them out and grow healthy.

My problem is my water used to be a little over 7.2 and now its 6.6. I know co2 is the cause of this, but how do i continue the injection of co2 and maintain a neutral ph? I cant add too many plants at this point cause im still working out some bugs in my hood, so i don't have the WPG i need for full grown plants right now.

Thanks

I wouldn't be too worried about your PH. Fish are highly adaptive and so are plants.
