Tank is 210 gallons altogether and has been up for about 3 months. I've been checking nitrate and phosphate at 24 hour intervals for several days now. Nitrates remain consistent at about 50, yet phosphates never register- 0.00 on my Hanna checker. I've gone from adding 15, to 20, to 40, to now 75 ml per day of NeoPhos with no difference in my reading come 24 hours later. Tonight I put in 100ml of the stuff and I'm getting to a point where this just seems insane.
I've never had this issue as part of cycling a tank. Definitely still experiencing the ugly stage- dealt with Dinos about a month ago, now I've been getting cyano. I'd let it run its course but for the fact I have some torches I brought over from my previous tank that are struggling. My LFS is suspicious that the Marco Rock I used (which I have never used before) may be absorbing the phosphate I'm adding, but that's the only lead I have.
Am I doing something wrong? The directions on NeoPhos don't actually address what to do if nitrate stays level but phosphates never register, as I understand at least, so I'm kind of at a loss (and ideally would like to avoid spending a fortune on neophos that doesn't seem to be doing anything right now). Any help would be really appreciated
