Nori has lots of phosphates. How about reef roids? I see a tiny bit of cyano on your sand. With the cyano do you think it's just using your phosphates?
I tested yesterday and my cleaning or new fuge light has had an impact on my nutrients. I'm at 0 phosphates again. Tested twice with hanna ulr. I even used new cuvettes. I'm Still around 10 on the nitrates. I have been backing off on the carbon dosing and nitrates are staying stable so I'm excited to see something is working. I dosed a small amount of iron yesterday to see if it helped my cheato growth at all.
I have been trying to find a phosphate heavy food to use over dosing straight po4. Anyone have any suggestions?
For now I'm happy with the reading as everything in the tank looks better than the last several months. I will continue to monitor and cross reference it with my salifert test.If I am not mistaken, the Hanna ulr kit is known to have an error margin of +/- 0.03 ppm. I personally do not think that you have zero phosphates. I would double check your readings against a calibration solution or retest with Elos High Resolution.
With 300 ml vinegar going in, you could be po4 limited..
If my memory serves, Bulent I think the Hanna has +/- .04 margin of error..
But the tank could still be 0..
I am a huge fan of the Elos high resolution po4 test kit.. comparing against it is an excellent idea..
With the cheato on line and the rdsb maturing, it may be tough to decipher upcoming nutrient readings..
Brandon, if I were in your shoes, I'd slowly and incrementally reduce vinegar over a long period of time until I registered some po4.. it's entirely possible that n won't change much..
I'm very curious to see how things progress..
Poor guy only lasted a couple days. Found dead this morning.ooooohhhhhh he's pretty :inlove: :inlove:
Hi Brandon,
From the appearance of the tank, with cyano looming, I agree to back off C-source dosing, at least until balance is achieved from a nutrient standpoint. Installation of bio media may benefit, as you seem limited with rock, not a bad thing, I love your scape! This may create more surface area for bacteria to home. Cheers
Nice fish tank
I suspect you're over on fishload for a newer tank and light on corals, causing a losing battle of nutrient imbalance. Fill that baby in with corals!
It’s tough figuring these things out. Look at copps tank loaded with fish, but everything else too, tons of big healthy corals. I think chaeto growth would help immensely if you had enough. It’s the imbalance between N and P thing causing the Cyanobacteria and I think Perry nailed it with C dosing reduction. How many total gallons of water in your system and how many pounds of rock and other biomedia?
