Phosphates can be a pain the ole sump! Zero phosphates are no good but too much and you have a problem! Ewww algae! So let's talk today about how the masses are keeping phosphates under control!

1. Do you keep a steady eye on your phosphate levels?


2. What plan do you have in place, chemically, naturally or mechanically to export phosphates?

Other than 10% weekly WC, I'm using NoPoX but seeing some limitations when nitrates are very low (3 ish) with my phosphates popping back up to .1-.2 ppm. Started adding Phosguard to see if that could help, but not exactly happy with that either so far. Giving it some time but also looking into perhaps Lanthanum Chloride for a more direct removal.

I’m having such a hard time with phosphates. I have a 80watt uv unit that I think makes it so no algae can reproduce but when I test phosphates they are super high! Like 3ppm high... how do I get them down to appropriate levels???

1) Yes (salifert)
2) ESV TE+ (2ml/day) carbon dose + Skimmer + Mesh Filter Sock! (also dose LoudWolf NaNo3 as needed cause those things drop no3 too, not just po4 - and low no3 is BAD!)

Edit: I should be clear, I target a range of .03-.07 po4 and 10 to 25 no3 relatively speaking for a mixed reef. I feed NLS pellet multiple times a day. Water change once a year... maybe?

I’m sure you came across the new optimal phosphate level thread judging by this post.

To answer your questions, and I hope this doesn’t cause any confrontation, is nothing really.

I test phosphates daily ensuring they are at the approximate range I want which is always ~5x N/P. In absolute terms, I maintain nitrate at .5 and phosphate at .1. I only use chaeto to ensure phosphates don’t go too high.

I primarily use carbon dosing to attack nitrates and end up having to dose about .01-.02 phosphate a day.

So no one gets upset at me referring research on the impact of phosphate deficiency on corals, other people have success at other ranges*

I’ve found the research to indeed be very impactful in my reef and maintaining a low N/P has led to much faster growth than I witnessed before.

Yes, I check phosphate with Hanna ULR Phospate checker. Currently mine are in the .02-.03 range.
I try and keep it in check with water changes, about 10% every 2 weeks and running a skimmer. I know the skimmer is for removing organics but some do contain phosphates. I did use Phosguard for a while and it helped. If they start to get out of hand I'll use it again.
I know some use GFO but that seems to strip the water of all nutrients. Not a good thing if not used with caution.

Strictly out of curiosity (not trying to argue about any specific "ways"), why not? I feel like there is a story here. :)
It’s just a feeling, but I think if it is added at a wrong time and/or wrong amount / photoperiod, it can outcompete beneficial bacteria for ammonia and nitrite, and push/keep the tank in an imbalanced state, which might lead to dinos/cyanos ultimately. I also think it competes for trace elements with corals, and in some cases this could lead to growth/coral color issues. Or it competes with some type of bacteria that’s present in the system and corals feed on those. Might be a coincidence, but I’ve pulled mine after 3 years, and the skimmate is lighter now & corals have a deeper color. I’ve tried dosing no3/po4 before, but I think I still was mainly feeding the algae in the fuge with that approach.
