Don't guess. Check with the TWDB (Texas Water Development Board) on well water quality issues in your part of the state. And, as stated, have your well water tested. When you first move in, it should be tested quarterly since conditions change throughtout the year.
In Texas, a large percentage of well water users find very high alkalinity (pH) levels due the high limestone content of the bedrock. The downside is that limestone produces high levels of CO2 so the DO of the well water can be below the levels needed to keep fish alive without pre-aerating it before adding to aquariums. If the area has alot of oil wells, there are alot of nasties that can get into well water such as sulfur and runoff from the oil fields. In these areas, most well users invest in large filtration systems to strip as much of the minerals, metals, and chemicals from the water as possible. Those who don't use filters, or have inefficient filters, are easily spotted by the discolored lawns they water since the chemicals and minerals tend to coat the grass after the water is absorbed or evaporated off. If your well comes with a filtration system already, just keep in mind that these filters don't aerate so, ensure the property's latest water test displays good DO levels before using the water for your tanks.
).Funny you mentioned the TWDB and I had never heard of them.Thanks again for pointing me in the right direction.
