I tested my water 24 hours after a 15% water change and realized my nitrates were around 50 and phosphates between 0 and .03- testing with the Salifert kits. I will admit I have been a little lax on water changes lately due to life happening. I have no skimmer but do have a refugium that run about 10 hours a day and grows pretty well. Over the last two weeks I have done two 15% water changes but not really sure where to go from here. I dont want to strip the phosphates but the nitrates being so unbalanced isn't ideal. I have anthias so I have an auto feeder that feeds BRS pellets (small amount) twice daily and I feed small amounts of frozen 2-3 times a day as well.
