:my wellwater is fresh ground water. i have kept my fish in it for a year now and no problem there. i was wondering, if it is low in calcium, will the calcium powder that i use on the frogs' food compensate for this? or is that a whole different thing? thanks, youre very knowledgable.
This is really only a concern if you keep your frog in it all the time. If this is a terrestrial set up that is then moistened there shouldn't be any problems as almost all substrates and soils have some calcium that will dissolve into the water (exception quartz gravels like aquarium gravel).
Also in most areas there is sufficent calcium in the groundwater to prevent this problem. If you know some one who keeps reef tanks they should have a calcium test kit and can run a check on the ground water for you. If your frog is kept in the water and the water is calcium deficient the animal can lose a significant amount of its body calcium to the water (up to 0.1% of total body calcium per day). The oral calcium supplements are unlikely to keep up with this rate of loss as the loss is continual. Do not try adjusting the water without knowing what is already in it as most of the supplements for adjusting calcium in the water will significantly throw off the pH (most are calcium oxide a fairly strong base and can run the pH up to 11 or 12 in a strong solution) and can cause burns.
Check the calcium level before you mess with the water.
