Short version: things are fine but something happened not sure what (yet). Have theories. Will know more soon.
Long version:
Got home around 1 am. Return section of sump was way down (return pump was sucking air) and ato was beeping. Tank water level was way too high. Initial look was fuge algae blocked weir in sump which caused restricted flow to return pump. This caused water level in return chamber to drop and ato to over fill to point it shut off. Good thing. Removed culerpa and chaeto to allow sufficient flow to return and tipped off about a gallon of ro. Cleaned weir in sump and in tank overflow. Threw in socks. Skimmer level is fine. But why did it grow so much algae so fast???? Something must have died or I overfed pellets (normally feed frozen) causing higher levels that spurred the growth? Also back up may have caused back flow into gfo causing release of po? Lights are still out but can already tell glass is filthy.
Tested :
25.2 C. 1.027. Ph 7.87. Po 109/.334. Ni 25. Alk 6.1. Ca 440. MG 1500+.
Levels are within my normal except Po leading to my 3 theories. For now just hoping everything made it and I was just overfeeding pellets. Will know more once lights on and glass cleaned.
Need to change gfo, order supplies this week.
Forcast for this weekend in california not looking good.
