:?: I read on one of the other forums that one (1) tsp. of baking soda per 5 gal of water will buffer the water and keep the pH at about 8.0-8.2. Any opinions? Or is there a better way. Our tap water is about 7.6 and about 10-12 on hardness.
Thanks, Sam

Baking soda raises Ph but does not buffer (keep it stable). Crushed coral as a substrate will buffer it for you.

Thanks for replying! I'll try crushed coral. Since my fish came from the pet store at 7.6 and are now at 7.8, I should raise the pH gradually?

if you are raising the ph by putting crushed coral in the filter--it will happen gradually enough--it's not like the drastic change that occurs when you add chemicals.

In that respect, using crushed coral is far better than baking soda, which [i:19e63012cf]will[/i:19e63012cf] change the pH instantly.

Is there an advantage to put it in the filter as opposed to mixing it in with the substrate?
Thx, Sam

Some fish suck up the substrate and filter it through their gills - if the substrate is sharp it can hurt them. Or so I hear - all of my fish do this, and I've never had a problem - I use 1/2 sand and 1/2 crushed coral.

Thanks for the info, I knew there must be some good reason for it.
