Hey guys, newbie here. Just started my tank this weekend. Current parameters and specs for my tank can be found in my profile. When I first filled the tank, I filled it to the water levels needed for the 75G tank and sump per the written "water level" mark on the sump. After running for the last three days, the levels fluctuate greatly. See pics for reference. I have a few theories as to why and was hoping someone here could confirm:
1) Theory one: I'm currently cycling my tank and dosing Brightwell QuickCycl (ammonia additive for a fishless cycle dosed to 3ppm) and MicroBacter7 at 15ml/day per the instructions. Is it possible that with the cycle and subsequent bacterial growth from the MB7 that the viscosity of the saltwater has changed and is resulting in a more viscous fluid, making the pump work harder and dropping the levels in the sump?
2) Theory two: barometric/atmospheric pressure - I noticed levels drop in the evenings and rise back up in the morning. Is it possible that pressure changes affect the ability of the pump and therefore affect the sump water level?
This is not affecting the performance of the tank, sump or return pump at all. Just curious as to why it's happening and if it's normal.
Here's a few pics for reference:
- Black line is early morning (not shown)
- Just below blackline is before noon
- "Water level" is after noon but before evenings
- below "water level" mark is after 6PM
Any help is greatly appreciated. Thank you.
