So I finally went out and picked up a phosphate test kit. I tested my tank and it read 0. Then when i went to do my weekly water change i tested the new water i was going to add. It read between .25ppm and .5ppm witch i now is high. I take it the algae that is in my tank is sucking it all up witch is why it is reading 0. I do use RO water from the local grocery store. I am saving up for a RODI unit from BRS. My question is what can i do to lower my phosphates in the mean time? I do have chaeto in the fuge. I was thinking about getting a phosphate reactor to run GFO and carbon but is it necessary? Anything else you would recommend? \r\n\r\nAlso i just switched over to a Reef Salt mix (Seachem brand) and i was wondering what should the parameters be and what should i be testing for (other then ammonia, nitrites, nitrates and PH)? As of now i do not have any coral but i am looking to go the route soon. I just want to be sure i can keep everything stable before i make the leap to go reef.\r\n\r\nThanks again.
