Po4 0

[Scotty333!!!]

Hi guys

Just got back from a business trip and while I was away my po4 dropped to 0 because the maid wasn’t feeding enough
Today some of my soft corals are tightened up , is this due to the lack of food?

It might be. It could be they just feel like being anti social. Low PO4 usually results in pale colors due to a drop in zooxanthellae numbers which can take time. Corals typically keep reserves of phospholipids so teh process of bleaching due to a lack of phosphorus can take weeks to months. Obviously feed your system more to raise measuarable PO4 above .03 mg/l but keep an eye out for other issues.
