hot fuge quick question

so my tank is 5 months old and pretty stable, at about 4 months my nitrates settled to about 20 ppm , i started to use filterd water, and removed the dumb bio-wheel , which brought the nitrates down to 10ppm, and also switched from IO salt to reef crystals. after about 1 month my nitrates are at 10 ppm. water change every 2 weeks. my tank is very clear althou i do have some hair algae not too much, proly from the first 4 months of unfiltered water. my fish are very active and have vibrant colors, clear eyes, never had a death in my tank.Also getting first small specs of coraline algae on glass and base rock. i would really like to add a coral something easy. but first i need to get my nitrates to zero correct?i have not tested anything other than my p.h. at8.3 and my nitrates @ 10ppm( ammonia and nitrite have been at zero since cylcing). ididnt feel clacium,phos, tests were need till later when corals come. what would be my best option of getting my nitrates to zero ?i feed every other day and my skimmer is working very nicely. i was
thinking about a HOT fuge.would any of these types be used with cheato for nitrate reduction. it would also give my scooter pods.my tank specs are listed below
its not very big thats why im hoping a HOT style would work. please help im going into info overload DAMN GOOGLE!

 

In my humble opinion, the nitrates don't need to be at zero. Lower is better, of course.
I was away from home for much of August through December and wasn't able to do water changes like I used to do. But, my creatures have been perfectly happy for the past 6 months with the nitrates at 20-40+.
A fuge should help lower the nitrates. So would a de-nitrifying coil. But, unless you are having major algae problems in the tank, I don't think the 10ppm nitrate level is a big deal.

 

I agree. Nitrates as low as you can get them but you need to worry about your lighting for corals. According to your tank specs you dont have any lights, somehow I dont think that is right.
