Not sure if people have seen this but Coralvue is releasing a new controller. The Hydros X3-S. It is a small controller with 2 sense ports and a salinity probe port. It is the cheapest option to get a Salinity probe. Looks like $225 and you need to buy the salinity probe separate. Personally I think it would have been perfect if it had a drive port as well. That way it could be used for a mixing station. $225 is alittle steep IMO too with no probes.
