Hey everyone,
Need some thoughts on sump Lay-out. The red area will be a fleece roller and where the orange is (Return chamber) will be the Apex Probes, dosing lines and ATO. Will this work?
Usually you do not want your probes in the return chamber as the water level will vary more there then the other section due to evaporation and top off. also if you top off a bunch at once the salinity and temp may change for a short time affecting all the probe readings.
Your dosing and ATO will be good in the return section as that will mix them quickly with the tank water.
