troubleshooting alkalinity

[kwirky]

it's min 8.1, max 8.3.

Not really. The xenia curls in on themselves in a real unpredictable way, and only for about 20 minutes if they do. The toadstools react when the PAR monsters turn on, but not to the pH. The green star polyps don't care about anything and neither does the frogspawn/hammer. And the echinophyllia frag, even though it's slow growing, seems bullet proof, between this tank, and the nano it used to be in. I made a newbie boo-boo of buying a small ellegance coral. It's feeding (gripping the food), but it's only been in there for 2 days. I'm going to be real antsy once it's been in there for a week. Heard that's when most of them die, if they do. *sigh*

I dosed 6 tsp's of baking soda the other night, and 6 more this morning, and it's sat at a rock solid 8.2 ever since I started dosing it. kH hasn't budged, but I'm going to continue this regimen since it's seeming to keep the pH stable. I don't have much of a calcium demand in there, so I'll just keep an eye on calcium and add kalk if I see it lower. I think i'm on to something, though, with the baking soda.
