I only have time for partial water changes, and I'd rather not forget anything I've observed, so the following is just for record keeping for me:
Chemistry and Equipment:
- The higher the alk, the faster my magnesium gets depleted. 10 Kh == ~1 cup of mag a week to keep levels up and 1 cup per water change.
- High alk produces calcium precipitate like no other. Everything gets clogged, requiring vinegar baths on everything every two months or less. Lower Alk helps tremendously.
- Alk swings are quickly expressed through my green slimer. If it doesn't look good or starts dying before anything else, you know something is wrong with my dosing.
- Magnesium swings are quickly expressed through my sunset and jedi mind trick montiporas. Nothing else will tell you immediately when mag dosing is off.
- UV needs bi monthly if not tri monthly algae cleaning.
- High capacity GFO is heavy. Hard to get a tumble.
Livestock:
- Iron clad SPS are my cali and blue torts, along with my Strawberry lemonade. Seems like they bare the brunt of swings like no one's business. Cross my fingers, knock on wood. They are also the slowest to grow.
- After the last tank crash, most high-end zoas and Acans do not experience a major change in polyps. They either shrink to just a few heads, or don't grow more than twice their original colony numbers.
- My melanarus wrasse likes to hide and sleep like she's dead at night: on the side and barely breathing.
- I hear loud pops every night when I begin night mode. Has been going on since I had the tank. Sounds like the glass is expressing a single crack, or the crack of a whip--just one loud crack. Can't find source. Can't tell if prior fish deaths are related, since there hasn't been a missing fish in a long time. Not including the ones that decided to jump. Not a lot of places to hide.
