The future second tank (a peninsula 120” X 24” X 28” ) is actually the reason the sump is so large. We should only have to add a second protein skimmer, everything else is sized to handle a total system volume of 600 gallons. I also didn’t want to have to start tearing up Sheetrock or core drilling around a running system, hence the full stub out of all the plumbing etc. This will be next years buildBTW…just finished stubbing out the remaining piping in the water change station room for another future tank! Also, the low pressure ATO reservoir tank is now activated in the system along with a high pressure system.
This system is the first one where I had to employ both a low pressure (gravity fed) and high pressure ATO system. Works awesome though!View attachment 37842
