Yeah I think I didn’t think it through lol. I saw the cool setups and wanted to do something similar. But thinking about it, I only have a 45Gal tank so it doesn’t make too much sense to move water from one brute to another to then move it to my tank. I think the 10Gal of RODI I keep on hand in the jugs is ok. Now I have to figure out how to return the brute and dolly lol. Do you ever store saltwater btw? Or just mix what you need
I do store it. This doesn't make sense, but I am having a much more stable saltwater mix in my aquariums versus my brute. Somehow in my brute my alk would constantly drop. It'd go from 8+ down to 7 or below in a week or so. My alk is rock stable in these aquariums.
I can't explain why. It likely was something else that happened, but I didn't change anything else at the time. It was even the same salt bucket.
Generally though, I think it's fine to store saltwater, but it's valuable to test it before you use it either way. My process:
1. Fill with RO
2. Turn on pump
3. Add salt, making sure I don't dump it all at once and don't over add salt
4. Use a piece of PVC to stir any settled salt
5. Do a very quick salinity test, trying to make sure I'm in the ballpark, knowing the numbers will move as it mixes
6. Add more salt or RO depending on 5, repeat
7. Wait awhile, turn on heater, retest salinity, repeat as needed
8. After it's fully mixed, do an alk test. Add alk if needed, and if it's really high I add a bit of acid to neutralize some
9. If I had to do stuff in 8, and numbers were way off, alk test again
10. Use it
