Low low nitrates and phosphates help

[oversd]

My tank in the last year has always had 0 nitrates and 0 phosphates with on and off algae blooms. I know a year old tank has to cycle and get into its grove but it seem to never change.

I was dosing Red Sea nopox but stop that over two months ago only ran it for about a month on the last algae bloom. The tank was looking great after stoping and now it’s start to bloom up again.

i also dose Red Sea alk, cal but haven’t needed to start mag due to water changes keeping up with it. I do water changes every other week of 30 gallons

There is a mixture of coral softy, Lps, Sps. About 20 to 25 still smaller frags for the lost part

i have about 10 to 15 fish


it’s a 125 gallon tank with a 40 gallon sump
- running cheato with opposite lighting schedule
It is growing quick
- curve 7 protein skimmer
Killing it out ever 4 to 6 days
- carbon and gfo in the brs dual reactor
- filter socks switched every 2 to 4 days
With 100 poundish of rock and 30 pounds of sand.

basicallyI’m trying to get this straight and be free of algae I was told by a friend that is I keep nitrates Above phosphates I’ll never have algae is this true? But I would like I get my nitrates to around 5 and phosphates to .05ish area

am I doing to much too little what do you all think

here are some pictures of my tank, some of them are a couple month old but it shows what keeps coming back every so often

Tanks will always have some algaes...but more important is coral health...and they need some po and nitrate to thrive. I suggest removing gfo until po is desireable levels and to increase trates feed the fish more...only what they will.consume in a feeding...but a couple times a day.

are you talking about feeding smaller amounts but more times a day? and when I remove the Gfo I feel as if I get more algae but I could always try again. then lastly should I keep carbon on?

Yes run carbon and feed more frequent small amounts. Take gfo off until theyre measurable if theres more algae growth return gfo start with small amounts, or increase algae in the fuge to compete with algae in dt...eventually youll find that happy spot.
