In need of some help!

[Surfking61]

I have a 30.gallon. It is about 2 months old. I have a skimmer and running a GFO and RO Carbon reactor. 26 lbs of dry reef rock that was cured. 40 lbs of sand which made a 2 1/2" bed.
I have one small clownfish and a very small.Radial File Fish. A couple of zoas, star polyps and a Ricordia. A week ago my nitrates were .25 using Red Sea test kit. Last night they read 64. Phosphate is reading .04. Doing a weekly water change of 20%. What should I do? Everything is okay right now but I knew that will.soon change if I don't do something drastic.

One.thing forgot mentioned. Diatoms came and was gone and overnight they are now back and worst than before.

Larger water changes, until those numbers come down. Once the numbers have come down, you may want to up you water change %.

Finished a water change earlier. Nitrates just tested at 16. Came Down a lot. I have everything in my hospital tank. I tested all the parameters in my tank and everything is right where it was, Salinity, PH, calcium and phosphates even dropped. Soon as the temperature in my main tank get back up to the temp of the hospital tank I can start moving everyone back over. Tomorrow I will be starting the Red Sea NO3.PO4-X. I will be switching over to all the Red Sea programs in the next month or two. I feel this will simplify my tank maintenance by using all products from one company. Also looking forward to getting my refugium set up after the holidays. Shooting to at least double my water volume if not more which should help keep my parameters more steady.
Just goes to show you how every system is different. This is my first nano though. Last tank was a 125 and was going for 8 years till we had to move.
