high phosphate

Hello, Beginner who started a fluval evo reef tank around 5/6 months ago tank fully cycled with not many issues. Only stock is 2 Clownfish and a red legged hermit crab. With a Duncan coral and Zoa frag that are both struggling and have barely opened since purchasing around 3 weeks ago. I...

Hi everyone, I’ve been monitoring my tank parameters closely and noticed that my phosphate levels are consistently around 0.90 ppm and nitrates are fluctuating between 40–55 ppm, measured using Hanna checkers. Lately, I've observed very slow coral growth, and some corals like Goniopora and a...

Hi, I have attached my test results from today. We have tried everything (we think) to reduce the phosphate. We have used rowaphos, reef zlememts carbo+ NO3 and PO4 reduction. Tank has a skimmer, reef Matt, all Red Sea and we do a 10% water change weekly. Everything in the tank looks healthy...

I have a 40 gallon tank and my phosphate is currently 0.5 and I’m having trouble lowering it. I use rodi water so I know that’s not the problem. I heard poly filter lowers phosphate so I bought it but it doesn’t seem to do anything. I’m trying to get it lower than 0.1 so I can finally add corals...

Hello everyone, i finally added my first softies. I did my regular water test today and my po4 was at 3mg/L. NH4, No2 No3 were all normal, but phosphates are high. All i have is 2 clownfish, 1 hermit, 1 astrea and 2 zoa plugs and one disco in a 250l+46l sump tank. I installed a diy refugium with...

I've had my tank up for 3 years now, manmade rock, and a finer substrate and I've been noticing that my phosphates will climb at a very rapid rate (day one will be .12, then 2 days later will increase to .2). I feed frozen food and nori daily, and have not changed what or how much I've fed or...

Hi all I’ve been having problems with my phosphate the past few weeks in my Fluval evo and I can’t seem to lower them at all I’ve done 30% water changes I’ve been running rowaphos in a filter bag in with my filter basket and in beside my return pump it was at a steady 0.25 since I’ve set the...

As the title suggests, my phosphates seem to be out of control at 2.0 and I somehow have zero Nitrates. The tank was neglected for a couple years after my daughter was born and essentially went for 2 years with no water changes or detritus removal and very few times emptying the skimmate (it...

Let's start with the history: I started a new tank (65g) about 3 months ago (red sea reefer 250 g2) - I skipped the cycling by using liverock & corals from old tank. - Inhabitants since day 1: 5" medium Powder brown tang, 3" small blue hippo tang, 2 clownfish, 1 damsel, 1 bi-colour blenny and 1...

I am having an algae issue. My Nitrates are .1 and my Phosphates are .4. What is the best way to get them in balance? Should I dose for nitrates?

Hi all, was wondering if anyone could share any tips on how they remove phosphates from their evo’s? I’m currently sitting at 0.21ppm! I’m running a table spoon of rowaphos in chamber 1 and doing 10% weekly water changes with ro/di water from my lfs which tested 0.02ppm for phosphate...

Hey! This is my first time posting on here and my second time trying to start a reef tank after bombing it the first time back in 2021 it was a total disaster. I started a 13.5g AIO back in july then transferred everything to a 32.5g AIO gradually, which seems to be doing well but after testing...

Hello, I have a 100 gallon DT with a 34-gallon sump. Probably 100 gallons total. I run a skimmer, and carbon in a reactor. I have previously run GFO mixed with the carbon but eventually moved to auto-dosing NoPOx. For a while everything was good. 0.1 phosphate, 1 nitrate. Over the last few...

Within past 3 months I’ve had issues with GHA. It’s gone progressively worse since I added T5 to my LED. T5’s only run at peak 3 hrs. Ive shut them off since and have reduced LED intensity (Marine Orbit Pro) but GHA has been slowly spreading. It’s not huge but definitely annoying. I have hermits...

Abstract: A calculation error led to the overdosing of tri sodium phosphate (TSP: Na3PO4) to a 700L (135 gallon display plumbed to two 25 gallon frag tanks) mixed reef system with deep sand bed that has been operating for the past 14 years. The overdose resulted in not the targeted 0.010 ppm...
