Well I finally managed to get it down to 0.17 with dosing RX and the water changes every three days. I then stopped dosing and water changes to see what it'd do. 24 hours after the .17 the reading came back with .28, then .39 the third day with no dosing/water changes. So it's currently climbing at .09 ppm/day.
Fish load is as follows:
4 firefish (full grown)
2 clowns (2")
1 yellow wrasse (full grown)
1 Carpenters Wrasse (2")
1 azure damsel (1.5")
1 Royal Grama (2.5")
1 aptasia file fish (1")
1 Purple tang (4")
1 Tomini tang (4")
Tank is about 3.5 years old now and I used 50 pounds of BRS Reef Saver uncured dry rock and a 7 pound Tonga shelf for one side. The tank cycled for 2 months before adding fish. I also have about a dozen Marine Pure spheres in the sump bubble trap after the fuge.
Current food mix, 3 Mysis cubes (rinsed), 3 Marine Cuisine cubes, 3 blood worm cubes (rinsed). Approximately 1/3 of this mix is used daily between the 75G (issue tank) and 20G AIO (No PO4 issues). I also dose with Seachem Stability weekly and have done so since the initial startup. Currently no other bacteria mixes are being used. About 4 months back I used a Dr. Tim's Waste-Away stick but pulled it out after 2 weeks. The tank did cloud up on day 2 of using the stick but cleared up in another 3-4 days. PO4 did not spike until about 2 months ago. So not sure if the Dr. Tim's gel stick is to blame.
