Phosphate 0.00 help

[jercompton94]

So these are my parameters
I’ve been having trouble with my phosphate I have been dosing for 2 weeks 1ml I just upped it to 1.5ml I have a nano 13.5 evo after I dose I would say after 2-3 hours it’s back down again

I’m dosing neophos and I have dosed the neonitro but rarly dose that

My question is how do I keep this up
I just lost a acro and my monti is suffering as well as Goni and encrusting corals
I have zoas, gsp, mushrooms frogspawn, hammers ,Duncan’s, alvipora.
But those seem to be fine

Sorry for the long post I’m just trying to figure out what I’m doing wrong

pH	8.5
Alkalinity	10
Ammonia	N/A
Nitrite	N/A
Nitrate	6.4
Calcium	440
Magnesium	1310
Phosphate	0.00
Salinity	1.024
Copper	N/A

I would tweak those params to 8kh , 1.026 salinity and feed heavy but watch your nitrates and if they rise above 10 dose a little vodka

Keep dosing. P attaches to substrate and will keep doing so until you hit saturation. Then it will climb like a fighter jet lighting up afterburners to engage the enemy.

I agree keep dosing and dose more each day until 0.03 ppm or more is present 24 h after dosing.

Personally I'm wondering about your lights. Seems off to me to lose so many corals due to low phosphate, and some of the corals listed are higher light corals. Also your lps and soft corals are fine, so this indicates not a nutrient issue. And if they are fine, do they actually grow?

I currently have the same problem in my 21 gallon. I dose Neophos 4 ml a day (2 in the morning and 2 at night) and nitrate once every 3 days. I feed heavy 5 days a week which includes reef roids, goniopower, Red Sea AB+, phyto blend, oyster feast, PNS and a frozen fish food blend. I’ve been doing this consistently for the past 3 months with no skimmer only filter socks and I have very little algae. I am tired of having to constantly dose to keep my nutrients up. I am lucky to get a reading of 0.02.

By vodka do you mean Tito’s lol but no serious?

Yes I got a ai 16hd prime and yes my corals been growing but it kinda slowed down

Yeh me too my reading would be good then it won’t.

You can always try feeding the coral with something like Reef Roids - this will also definitely raise your Phos. I agree that it might be your lights. I recently figured out that the par was way to low in both of my tanks, slowly increased the lighting and growth took off (as well as consumption of Alk and Cal 2 part - almost doubled)

Well I tweaked it lower since I thought it might have been too high I don’t have a par meter

I had the same issue by dosing neophos @1cap 5ml a day and that's what the directions said to dose. I got tired of constantly having a big ZERO so I doubled the dose daily and viola the system would hold phosphate. Also you need to test daily. Like buddy above said it'll shoot up once it releases back so take caution.. your lights seem to be fine IMHO. Looks like your at about 20% by your screen shot.

Fwiw my system this week bottomed out with phosphate. I was using tropic marin plus NP and suddenly the po4 hit zero. Frogspawn lost 60% color and some montipora starting to lighten up in color so back to good ol' neophos and calcium nitrate. This carbon dosing is supposed to be mild but ime it's a bit more aggressive then left to believe.

What size is the tank? I have AI Prime over a 15 gallon softie tank (zoa’s and mushrooms) set at 70%. Your settings are much lower and the tank looks larger than my 15 gallon. Corals get 90% of their energy from the light.

Ok thank you ima try to up the dose and see if that helps I tried to start off with a small dose just in case but I will do that

My tank is a 13.5 I could raise it more but also my light is lower than 12in on the stand my shelf would block it if I raise the light up to about 12in

I’ll try to raise the intensity

No skimmer = no vodka

That’s rarely warranted with phosphate dosing. It can take far, far more than calculated to overcome binding to rock and sand.
