chemistry results after 2 weeks cycling

I put 2 fresh raw shrimp in 75g tank on tuesday. Here are my chemisty results:
NH3/NH4 = 0.50

NO3 = 20

NO2 = 0.25

Ph = 8.4

Spg = 1.020

Temp = 78.0

So, do I leave shrimp in there and do a 30% water change now? Should we hook up protein skimmer? Please offer suggestions.

I would let the cycle go, no PWC, those spikes are part of the natural cycle. You should leave the shrimp in there, it will keep doing it's job.

Age is relative, you are only as old as you act....of course, this works in reverse....

Questions loved, heeded advice greatly appreciated!

Let it go. Wait until you see NH3 and NO2 at zero before doing a water change. You can remove the shrimp in a few days if the smell gets to be too much. Once you see a large spike in NO3 with no detectable NH3 or NO2, you can do a large water change and monitor levels for another week. If all levels remain appropriate you are ready to go. Remember that you should add livestock very slowly at first. I would not worry about the skimmer yet. You can start using one if you want, it will not hurt anything...won't really help much either. Good luck!
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
