Well i water tested today and i got the following.
8dkh as always on salifert
5ppm no3 salifert
0 po4 on hanna....
So i was like wth i have been getting .09 lately. Well apparently i had been doing it wrong. I was pressing the black button and not holding it. Therefore i would never get a timer countdown. I would add solutiong once c2 came out , swirled it untill diluted, put the tube in and pressed the black button. It would blink a few times with a --- on the screen, and i would get a number. Apparently this was wrong, since like i said you must hold untill countdown appears to get the correct reading.
Anyways, after seeing 0's today and last night i wondered ..whats eating up all the phosphate? ?. I have gfo offline as well as gac. Im still running matrix and macro (cheato). So i decided to feed the tank and test an hour later. No way i could have 0 po4. Well an hour later i got a .04 a bit better. Guess i will have to keep an eye out on this, since i dont want to starve out the tank again.
Maybe .04 PO4, maybe just particulates in the water effecting the reading. This is why I prefer the ELOS Expert high rez kit rather than the Hanna. Sahin and other long term reefers recommended this kit. Only a few places sell it, and don't get the regular kit which is no good, must be the expert high rez kit.
So the super clean rocks and clear water make sense now, 0 PO4. You will find that things can suck up PO4 like rocks and new sand. It's probably best to treat feeding like dosing and get a schedule of feeding set and then adjust as needed. I've been making a habit of feeding a little coral food every day with a big gob of it once or twice a week.
