Hey Guys I am in need of some advice. I have been in this hobby for 3 years now and my aquariums always seem to have a few issues. I realized that as much as I thought I knew and the effort I put in, I could never stay on top of things and my aquariums never looked as good as I hoped. Ich, Aptasia, coral dying. After moving my 250 Gal to my new house I decided to hire "professionals" to take care of everything around two years ago. This was not cheap with people coming every week, but my tank was looking great for a period of time. Since then I have been through 2 different companies. I have run in to the same issue with each company, I am not strict enough with them and they start missing appointments and there are issues. After an issue with Ich a few months back I tested my aquarium which I was told was (doing fine) and my nitrates were off the charts (200+!) I doubt they have been doing much for 6+ months other than billing me and cleaning the glass.
Finally I decided I am the only one I trust with my aquarium! It is time for me to get educated, stop flushing money down the toilet literally

and take over! I have some of the "best" equipment an Apex controller, UV sterilizer, big new skimmer and nice pumps all at the advice of my "professionals." I even recently bought a denitrator (this has been a mess) and was more of an impulse buy (oh **** my nitrates are crazy)
What I need to do now is get my Nitrates under control! Even with a denitrator it would take years to cycle my 250 Gal- 75 Gal sump. With only a few drops per second. I have been doing weekly water changes (30%), gravel vaking but I think I need to do something more aggressive.
I stumbled this vodka thread and was hoping to get some advice. What can I do to drop Nitrates down enough to start enjoying my aquarium again? All of my nice things are dead, I have a few fish, mushrooms and a few rose anemones but my once glorious aquarium now makes me sad. I need advice before I just give up and sell the thing

All my other basic tests (PH, Nitrite, Amonia) are good.
How can I drop these nitrates to non-toxic levels ASAP? What would you guys recommend? Would Vodka be an Option?
