    The relationship between Nitrates and Phosphates

    Hi everyone, my first thread so go easy on me! Now to provide a bit of context to the problem, I have a mixed reed and I know everyone says not to chase numbers - which I agree with. But if your tanks a few years old you can easily have PO4 at around 0.40ppm and Nitrates around 40ppm or even...

    Which food is best for corals without phosphate spike ?

    I am using reefroids but my god the phosphate spike is very high , .10 after 12 hours of feeding with refugium and ozone (I know ozone doesn’t impact phosphate ) and I am a little concerned Any one has recommendations on coral food without sending my phopsphates out of whack ?

    Restoring from tank crash. Continue increasing nitrate/phosphate dosing?

    A car accident last October led to some poor husbandry for half a year. I couldn't do water changes and driving to pick up consumables was difficult. I've recovered a substantial amount and the acro & monti colonies I have left are starting to colour back up now that I have things under better...

    Phosphate swings throughout the day?

    Hello, I'm trying to troubleshoot some interesting Hanna ULR Phosphate Checker readings that I've been receiving the past few days. Do Phosphate levels in reef tanks have 'Cycles' or level changes throughout the day? The reason I ask is because I'm doing carbon dosing in my reef tank and I've...

    How stable does nitrate & phosphate have to be?

    I'm dealing with a nutrient deficiency in my tank and have resorted to daily dosing 2ppm worth of nitrate (with potassium nitrate) and dosing 0.2ppm worth of phosphate (with potassium phosphate), daily. It's 500L of water volume and I'm adding 2g of kno3 and 0.2g of kpho3. I'm adding them dry...

    Rod’s Food high in phosphate

    Anyone experience high phosphate after feeding Rod”s food? I tested before and thirty minutes post feeding and phosphate jumped from .04 to .15 in a IM25 Nuvo. Portion size Is there a suitable food besides mysis that does not blow up phosphate levels?

    Phosphorus vs Phosphate

    The weirdest thing has been going on while testing. So I have the hanna phosphorus ULR and the Phosphate readers. So I know they have a conversion chart for the phosphorus and for some reason I had a 200 plus ppb reading last night. So i was like no way something happened while testing. I said...

    High Phosphates - No Algae

    Hello All. I have a 90G DT with TS Saphire 34" sump. Means of filtration are(2) 4" filter socks, Aquamaxx Q1 skimmer, and refugium with chaeto. Other than live rock in the DT, I have MarinePure spheres in the sump. Currently it's a FOWLR system with 6 "larger" fish of 4-6". I feed fairly heavy -...

    Mid to high NITRATE / Low to zero PHOSPHATE BENEFITS?!

    phosphates help growth in coral but also brings algae and lose of coral color. How important is phosphate in saltwater aquarium? I rather have mid nitrates levels 15-20 ppm maybe push 40ppm before 10% water change all while keeping phosphate levels low. Calcium will be readily available and more...

    NOPOX Recipe

    I should really have started doing this a couple years back. NO3PO4-X usually sells for $45 give or take, and I could make so much more by just buying the Vodka, Vinegar and mixing in with RODI so what follows is a Quoted recipe from a 5yr old Nopox Recipe thread that I found on R2R. Credit goes...

    Nitrate readings all over the place and possibly through the roof

    So i ventured back into coral on my tank like 6 months ago after a crash a while back from what i think was turkey salt. Tank is 2 years old and so far most of my coral are happy. I have a couple acros browning out (though me PE is great on almost everything, acros included) so i decided to get...

    Dino’s or Diatoms?

    Hi all, I’ve noticed an increase of brown patches on my sand bed. 5 days ago my phosphate was 0.22, today my phosphate is 0.07. Do you think it’s dino’s or diatoms? Not the clearest shot but hopefully you’ll be able to tell?

    Leaching phosphate from rock

    Hi all, my tank is 3 months old and I have made the decision to cycle some Caribsea life rock away from my main display which is eventually going to replace existing rock in my tank, as I believe my crazy high phosphate levels of 0.21ppm are being caused by leaching phosphate from the rock that...

    What cartridges should I replace in my rodi system when detecting phosphates

    I’ve been struggling with high phosphates and it seems like my rodi water is to blame. I was wondering what cartridges I should change and what exactly the membrane filter does because I for some reason can’t find what it exactly does. I exchanged my sediment cartridge recently and that’s...

    Does potassium nitrate and potassium phosphate react?

    I currently dose 1mg kno3 and 0.04mg kpho3 weekly but since it's weekly i often forget to do it, sometimes a couple weeks in a row with visible degradation to acro health, so i want to automatically dose it. I only have one channel free on my kamoer dosing pump. Can i mix potassium nitrate and...

    How low can Phosphate and Nitrate be? Sulphur denitrator & Lanthanum reactor methods

    Help with high phosphate

    Hello, so I messed up the other day and put a dry rock into my tank (since my LFS said it was fine to do so). After adding the rock my phosphates have spiked and are "maxed out" at 0.9 on my hanna ULR test kit. Before this my phosphates were at 0.03 and this is the only major thing that was...

    Add phosphate with doser then remove it with gfo reactor on timer?

    Is it possible to dose phosphate during the optimal period of the daily photo cycle, based on the best time corals are known to absorb phosphate from the water? Then to keep it from climbing, and reduce the time spent monitoring, remove the phosphate daily, with a GFO reactor on a timer, running...

    Hello everyone! I’ve run out of knowledge, so i’m turning to my favourite forum for the best advice. We have a redsea 250 full of euphyllia. i’m not getting the “fullness” or polyp extension i know i can get, despite the “big 3” being stable thanks to our apex and trident. Iodine was...
