I’ve had this BTA for a week and it’s been great it’s opened up moved around a lot but the last couple of days it’s been mostly closed up and hidden and I flipped the rock over to look at it and it’s been like this for hours. What’s wrong? Nicrew gen 2 lights. The only flow is from a aquaclear HOB. I would say it’s a pretty moderate to low flow. Mostly white light dimmed with some blues. PH 8.0 Nitrite 0 Nitrate 0 Ammonia 0. Salinity is 1.026 and temp is 78°F. I used API saltwater test kit. And Hanna tester for salinity.
