bumping up PH? and a calcium question....

[Big_Pun]

Why is that? Excuse the newbish question...

no prob... I've been trying to fix this for a while but it could be lots of things: my house oxygen levels may be low so slimmer is pumping air in with elevated Co2 so i use a Co2 scrubber on it now(helped a lil), i also run bio pellets which the effluent carries Co2 again and i combat this by putting effluent into the skimmer so it's aerated. the kalk just helps keep ph up and with the brand I use also mag and strontium and of course calcium since my tanks demands are high
"The kalkwasser solution contains water, calcium ions and hydroxide ions. The calcium ions obviously help to raise the concentration of calcium in the water, a good thing for animals and plants that use calcium for their skeletons. The hydroxide interacts with dissolved carbon dioxide to form bicarbonate, and together with any remaining hydroxide ions, this raises the alkalinity, thereby buffering pH and inhibiting acidification." wetweb
