How often does the water gel need to be replaced?
You can supply many species of spiders and scorpions safely and permanently with a drinking water supply using a water gel (JBL TerraGel). The gel introduced into the terrarium needs to be replaced daily. Gel which has been prepared can be kept well sealed in the refrigerator for up to a week and used for refilling. As the animals enter the drinking bowl with the gel, contamination occurs, which makes regular replacement necessary.
