unable to raise phosphate

[Sky2Sea]

I have been dosing neophos for about 2 weeks now but it still show 0. any suggestions ?

How much are you dosing? How big of a tank? What kind of filtration are you running? What types of living things do you have that absorb phosphate (high/medium/low coral volume, macro algae, nuisance algae, etc.)?

Dose more, if you believe the kit. It can take a huge amount to overcome rock and sand binding.

Id dose 0.02 ppm per day.

Okay, I'll give it a try. THANKS..

80 gallons, 5 ML per day, standard sump with sock plus protein skimmer, low coral count, dinos (large cell ampid I think) also some cyanno is present.

I have been dosing 0.03 ppm phosphate in my coral qt tank and still a zero

i had the same issue. i think my rocks were binding it as well. just feed heavy, especially pellets. i actually have been crushing my pellets up like reef roids and using that to target and broadcast 2 times per week. last po4 i checked was .02.

I tried reef roids before the neophos but it had no effect. I will try the pellet crushing, THANKS..

I am dosing 20ml of NEOPHOS in a 125g tank. I am using a Salifert Phos test and getting 0.0. I have only been doing it a few days....keep dosing?

5mL tells us nothing. Talk in my language (PPM).

What does 20mL in 125g equate to? Is that .01, 1, or 100 ppm?

You gotta be specific when talking about phosphate dosing.

If I told you I was dosing 5000 mL of 2-part to my system what would you think? I hope you would be thinking what the total water volume was, and the dKH/L of the added solution. 5000 mL wouldn’t mean anything if the dKH/L was 20 and the total system volume was 10,000 gallons. On the flipside if the dKH/L was 10,000 and the volume was 100/G then that would be very significant.

It's ridiculous of Brightwell, that despite a long web page of "technical information", they do not once mention the potency.

I think they changes the potency and you'll need to check your bottle.

Some bottles say 1 ml in 1 gallon boosts phosphate by 2.5 ppm and some say 1.2 ppm.

Either way, 20 ml in 125 gallons would add more than 0.2 ppm.

However, that amount may easily bind to rock and sand, so if you believe you kits is working right, I'd keep dosing.

That’s insane actually insane. Reef roids is like Phosphate powder
