Day 32 (10/20)
Did a 20% water change. Starting to see algae get a bit stronger, so will keep monitoring. Going to skip feeding my fish tonight.
Got an AI Nero 3 and put that in the back, lower, right of my tank—will flow across the back, shooting from right to left—and put it on a random setting and will fluctuate between 10% and 30% power. Hoping it helps with some detritus and general tinkering with preparing for corals that will need more flow, when I get them.
Also decided to turn on my protein skimmer for the first time, to see if that helps with some of the debris, leftover food, etc.
Will test my parameters tomorrow to see how I need to adjust after the water change.
Day 33 (10/21)
Tested my water this AM, and here's what I've got:
- Salinity: 1.026 (same)
- Ammonia: 0.05 (Down from 0.1)
- Nitrite: 0.05 (Down from 0.2)
- Nitrate: 25 (Up from 10)
- Phosphate: 0.9 (Up from 0.03) ***
- Alkalinity: 9.5 (Up from 9)
- Calcium: 526 (Up from 515) ***
- Magnesium: 1520 (First time testing)***
- pH: 8.2 (same)
So, I think my Phosphate and Nitrate are both up, because I'm seeing waste in my tank (i.e. poop on the sand). I have nassarius and trochus snails, 4 blue-legged hermits, and a tiger conch, and none of them seem to be eating it.
Any idea on how to bring those levels down? I can definitely do another water change and vacuum my sand, but I feel like the poop is heavier than the sand, so I'd need to replace my sand. I can definitely add more sand, but worried I would lose all the good bacteria that is in there currently.
