alkalinity too low???

[WaterLogged]

My alkalinity is at 5.04 dkh or 1.8 meq/l from 2 sources mine (hagen) and a local lfs (salifert). Is this level dangerous for the inhabitants. Should i be making a big change or can I raise it gradually?

I was thinking of baking soda. My math puts me at 32 g baked sodium bicarbonate will raise alk by 1 meq/l in a 90 gal tank. Does this sound right?

Other levels include calcium at 360 ppm. And Ph is at 8.0 morning and 8.2 at night.

Thanks,

go slow, raising the hardness too quickly is hard on the inhabitants.

Will rasing 1 meq/l a day be too fast? Does anyone recommend anything?

You should also test for magnesium. Your calcium is not that low although I usually try to shoot for right around 400. As has been said raise you alk. slowly and keep testing. You might also have to play with your magnesium level a little to get your levels to stabilize.

In my experience an extremely low alk will cause pH swings greater than what you are reporting. Raise it slowly, but don't get too concerned or excited. If you pH was constantly lower than 8 or had swings of .5 or greater, then you have a bigger cause for concern.

Raising your alk will help get rid of your cyano problem
