sg. from 1.024 to 1.021 overnight

Hi,

My DIYed auto top-off system failed last night and approx. 18 litres of fresh water was added to my tank over a period of 1-2 hours to my best guess.

Specific gravity reduced from 1.024 the night before to 1.021 this morning. Checked the LPS (brains, hammer) and they isn't any unusual sign... replaced about 6 litres of water with new salt mixed at 1.024 this morning, and I was thinking of raising the salinity gradually back to 1.024 over 2 days period.

My question is - will there be any harmful effect to the LPS if I do this? I know fishes will have no problem with this, but am not sure if the LPS can tolerate such a low sg.

Your valuable opinion please.

p/s: luckily didn't flood my living room, the floor is leveled so well that ALL the overflow water was drained THROUGHLY via a drain hole located 2 m away in the kichen attached to my living room Phew.... must thank the worker who did a fantastic job in leveling my house floor

I believe it is still within range for most LPS. Especially those that are from shallow waters that will experience salinity drop whenever there is rain.
