Ok so sense my display is empty except for inverts and coral I thought this would be the right time to attempt something like this, I want a skimmer and I heard you need a constant water level but my sump as one chamber and a little container thing for bioballs/rock rubble so evaporation changes the water level constantly. My first question is would baffles help solve this problem? How far away from the pumP would they Need to be because it's small and I'm even debating whether a sump would fit. My other idea is getting a 20 gallon I havE and drilling and puttin a bulkhead on either side connecting it to where he pump is now on my sump and putting the pump on the over side of the 20 and using the 20 as a skimmer chamber and refugium. Sorry for the wall of text but I'm completly new at DIY maybe there is something else I can try?
