Need some help and don’t know which section to post.
1. Realized every week or so I have to adjust the water valve outlet. When I see the water movement slowing and water level drops. Have to re-adjust again. Is it normal? Or is it due to blockage.
2. Has some diatoms issue last 3 days. Got a feeling something is not right but couldn’t find the cause. The next day, a cleaner shrimp took a dead goby out to devour. Did some tests, nitrates went up. It’s also my weekly microbacter dosing. Cleaned the glass, switched off the lights and usual sop like changing filter etc. Today the diatoms are gone. Water is clear again. Did some tests and find that the calcium, magnesium went up compared to last week test after WC. Is it possible? Only dose calcium buffer daily for the past 3 days according to dosage
Last Friday test
salinity 1.025
ph 8.1
calcium 425
mag 1350
8.5 dKH
nitrates 1
Today
salinity 1.025
ph 8
calcium 465
mag 1455
8.5 dKH
3. Some tiny white worms on the glass. Closest I can find on the internet is round/detritus worms. They seem short but some moves pretty fast. Are they harmful? Trying to take a pic.
