phosphate

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...

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 ?

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...

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...

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...

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?

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...

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 -...

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...

Hey all, Parameters as of right mow no3: 6~ppm Po4: 0.09ppm alk: 10 Mag: 1350 Ca: 440 some background to start with, I started the tank over 2 months ago now, using dry sand, and live rock (had been barrel baking for 4~ months in barrels with bottled bac, no coralline or anything, may as well...

Hanna Instruments 7 in 1 Marine Checker/Photometer ^ ^ II II II II Has anyone had any experience with one of these? I know they are new to the market; I don't even know if they are released yet...

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...

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...

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?

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...

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...

I have a 75gallon tank set up for about 2 years. sump has live rock, and so does the tank. Nyos120 skimmer tht only skims less than 1/2 the cup like every 10 days before I clean cup. growing Cheato. Using filter floss I clean every week or so. Refugium light is on for 8hrs and use Rodi water...

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...

I’ve been using a Sulfur Denitrator; and a DIY Lanthanum Chloride dosing pump into a reactor with pleated filters. Finally getting good control and stability on Phosphate and Nitrate has been a game changer. Polyp extension is amazing and some monti/lepto skeletons are even regrowing. My...

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...

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...

So I have a 32 Gal Fluval Flex that has been running for about 9 months now. Recently, I had a couple Zoas and a GSP that have been closed up for a few days so I decided to test my water. The results were: Ammonia: 0.0 Nitrite: 0.0 Nitrate 0.0 (checked twice w Hanna checker) Phosphate:0.37...

Hi everyone, I am new to the reef2reef forum and also reef tank. Recently I bought a maxima clam. But sooner or later, I found the phosphate level is too high (>2ppm), which kills the Duncan and hammer coral inside. I used phosphate removal to reduce the phosphate down to 0.25. My clam still...
