NO3 dosing and broadcast feeding?

[carnthetiges]

I have very low NO3 that i'm looking to rectify in my 15g.
Safest option looks to be supplementing NO3 as i can easily measure and slowly increase it.

I'd also like to start feeding my corals. I have a leather, some GSP and various morphs.
They're pretty unhappy at the moment, i'm hoping bringing PO4 down, NO3 up and start broadcasting reef roids or equivalent will improve things.

Should i hold fire on the coral food until NO3 is up where it should be?
Will it throw out my numbers and complicate trying to find a PO4/NO3 balance?

Cheers

You can start feeding the coral now, just realize when you do that in a small tank a little goes a long way. Feeding roids also will no doubt raise PO4 also. So I would get ahead of that with a little GFO. Just keep regular tests up and make sure not to let either bottom out, the coral will go from looking bad to dead very quickly.

I agree, you can feed any time.
