I need some dead coral i think to get my ph up at 7.0 and keep it around 7.0. I was told dead coral pieces would be best. If so were can I get them and what cost?

coral gravel is what you'll need. coral skeletons as decor won't do much. any driftwood will lower pH FYI.

so crushed coral will work fine? how much 20lbs to start for a 300 gallon?

also i have a big gar and big cats in my 300 gallon. my ph is 6.0 and i dotn want to shock them or stress them out. so what should i do to get the tank to about 6.7 or so with out freaking the fish out.

Driftwood will automatically lower your ph, it is entirely dependent on your kh...

If you get a 20 lb bag of crushed coral, don't add it all at once. Add in small amounts, wait and test ph.
