I have been cycling 30gallon saltwater for about 8 days now. 36 hours after dosing 4ppm of ammonia there is no trace of it. There is also no trace of NitrItes. NitrAtes are around 50ppm. Should I do PWC
and add some more ammonia to keep it cycling some more or should I do 90% water change and consider it cycled?
I will not be stocking it at least until July 8th so I am not in a hurry.
Some info about my tank,
40 lb of cured live rock
40lb of dry base rock
40lb of live Carib Sea sand
10 gallon sump/refugium
CPR protein skimmer with rio Venturi 600 pump
200w power compact light 10k/actinic
Also is it good time to add PurpleUp for coralline algae? I read somewhere that keeping acitinic light on during cycling will promote growth of coralline algae. I am afraid that it may cause algae bloom.
