I would not change the gfo if your po4 is .03. I did and I got burnt tips and algae started to grow on the tips within a week.

Can you please elaborate on what happens from your experience if Po4 gets too low?I haven't read through this thread fully, but in case no one else has chimed in about this... You all need to be very careful with dosing nitrogen sources and driving PO4 too low. PO4 being too low will result in things far worse than some pale corals.

I have .03 Po4 and havent seen any major issues.
ThanksCorals start to die, phosphorous is an essential for life. If you're reading .03 you're likely fine, but I and others have had problems when there are undetectable levels on a Hanna checker.
Great coloration!So I brought my no3 up. We'll over shot to be exact lol. Went to 11ppm. Got it stable now at 7ppm. My sps responded over night! Not a huge change but when you spend most of your free time starting at them you notice subtle changes. Started using kz trace elements for sps a couple weeks ago and wow! It works awesome!this is day one after acclimating. From battle corals.after a couple weeks but before bringing my nutrients up.taken today.
Great!Thanks! That and dosing trace elements. That's the most dramatic change out of all of mine but they all got better saturation of color after I did it.
I'm having a similar issue... my nitrates show around 12 on red sea kit my phosphate is 0.00 on hanna and I see stuff paling out... is it possible to have nitrates in that range with no phosphate? I only have 2 clowns and feed them afew pellets 2 to 3 times a week. And half they don't eat... I don't have any brown algae in my tank but I do have alittle cyno, I've been dosing small amounts of vodka for a month maybe... started at .4ml daily for 3 weeks and now I'm doing .8ml daily I havnt seen nitrates drop and cyno starting... I don't have to clean my glass except for a light film here and there and blotches of the cyno. I started dosing red sea energy a and b to dirty up the water and 2ml of oyster feast a day along with acropower to help feed the corals... I have a 8 bulb sunpower running 6 blue+,1 coral+, and 1 purple + I've been running them for 6 and a half hours a day and the corals are 27 inches from the fixture. I don't necessarily think that's too much light for acros. So I'm guessing they are starving because I've observed colors greening where they aren't looking to be bleaching. My question is should I stop carbon dosing? Cut back the skimmer since it's oversized for my tank... may run it day on day off and try and find a happy medium. I don't think dosing nitrates is going to help... it's my guess if I'm not getting a brown film on the glass my to clean at all my corals are starving. Any incite would be greatly appreciated have some really nice acros and don't want to lose them. I feel like I know what I need to do but would love some inciteI'm in this same predicament, I think. I dosed some potassium nitrate a week ago and they are staying at 5-10ppm (API)
Phosphates via Hanna are 0.00
API phosphate test shows 0.25ppm
Which should I believe? I feed mysis once a day and run a skimmer. Could phosphates really be 0.00?
Just tested phosphate via Hanna and got .05 my nitrates are around 10... I'll keep dosing reef energy a and b and feeding oyster feast and see how things turn out.
