Cycling Question

[Irishfist25]

i recently set up a 2nd tank, its 100g and will be FOWLR only.  it has been running for a week now, but i didnt do any water tests until today.  in hindsight, i realize that wasnt the smartest thing to do, i just had so many other things with the tank to do after the initial set up, that testing got pushed back until all else was finished.  I have approx 50 pounds of LR with about 40 of that coming from the member i bought the tank from.  He had it cycling in his setup for about 6 months prior.  I also used half of his sand and half of new ocean direct live sand.  i was hoping that by using mostly cured LR and half of his sand that i would drastically cut down the cycle time.  So i tested for ammonia, nitrates, nitrites, and phos. today and here are the results:

 

ammonia-0- Api test kit

nitrites-0- api test kit

nitrates- 1.5- red sea test kit

phosphate- 5+- ted sea test kit

 

obviously im worried about the high phosphate, im assuming its coming from some die off from his LR, they were keep in  5 gallon buckets full of tank water for approx 24 hours prior to me putting in my set up and the same for the sand.  Plus, the 10 pounds or so that wasnt from him, was just dry rock that i took out of my last set up when upgrading tanks.  has been dry for about 7 months.  With 0 ammonia and nitrites, but 1.5 nitrates, is it possible that i missed the initial spike during that first week.  I didnt feed the tank during that time, because i knew there would be some die off and thought that would jump start it.  I guess my question is, is it normal for phosphate to be that high this early and should i do multiple WC this week to bring it down, or would that hurt the cycling process as a whole.

If you wait a few days, you'll likely get a little algae that will snap up the phosphates and nitrates if you just add a little light. I'd just hang tight for a little bit more, then add some herbivorous elements of your cleanup crew to start working on the algae.

knock out the hi p04 with Lanthanum Chloride now before theres any livestock added. easy to do with a filter sock and powerhead.
