Figure out what it evaps and try to top it off daily. Just don't let it get that low before you top off. And top-off before you do water changes, you will have a better chance at keeping your SG consistent.
As everyone said RO, do routine water changes, limit lights, and monitor what you are putting in the tank food/additives ect. Start somehwere there's no magic cure.
I am still fighting it in my little over a 1 year old tank and my other mature tank is fine, they share the same sump/system water. Lighting and in tank flow are the primary differences. It's gotten better with a switch from 10k to 20k MH but, a few of my coal are suffering from the transition of spectrum.
Do some routine maintenance and things may improve somewhat over time.
Some folks are lucky to keep the NO3 at zero. I never have been able to, I get very close but not an absolute zero with the Salifert kit
