phosphate

I'm currently running a 32 Biocube. Here is livestock: 1 Clownfish (going to be getting a female soon) 1 Snowflake Eel Parameters: Nitrates 34.6 PPM PH 8.1 Phosphate: 0.49 PPM I'm trying to get phosphates down to 0.003 at least. I've added a refugium recently so I think that'll help. I've had...

Hey all, So over the last few weeks I have found tufts if gha in my display. They don't seem to be growing but they are there and driving my crazy. So I decided to break out all my checker and run some test. Well I found I have zero nitrate (hanna hr) and .03 phosphate (hanna ulr). I am...

I'm worried the phosphate has gone up so suddenly. Is this a bad reading? I'm considering buying a GFO & Carbon media reactor. I already have an octo bio pellett reactor and chaeto Growing. I am feeding too much? Could using Bio enhance and coral essentials coral nutrition a and b cause high...

Hi, I’ve noticed that most of my euphyllia have receded flesh from the bottom (hammers, torches), but they opened fine during the day (maybe slightly retracted but unnoticeable). The only issue I’m seeing is 0 phosphate. I’ve tested twice, Last Friday and today with Hanna phosphate URL. Here’s...

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...

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...
