phosphate

Hey guys, I’ve a 60 gallon cube setup now with almost 4 months. I run it with two canister filters, one of which was on a smaller reef tank so was already to go for this tank. I’ve always being growing a lot of hair algae, and started to figure out it was my phosphates. I’ve been doing water...

I have had this tank running for an over year now just recently had some issues with a few of my Acropora. Seems if some had some burnt tips recently and some having some minor flesh die off. I tested and the only thing out of range was phosphate which was .23 ppm. I have lowered it over the...

I can NOT get phospates above 0.01. I like to do a water change at 20 for the nitrates, but would it be ok to leave for a few days to see if phosphates go up any further? I think there's enough live food and algae in the tank for the crabs and fish to eat, so I could hold off on feeding for a...

I’ve been trying to get my nutrients to a decent level for a while. Initially I had high phosphate and used gfo to keep this in check. I’ve used some form of diy algae scrubber alongside this. While gfo and diy algae scrubber worked for phosphate my nitrates were still higher than I wanted. I...

Hello everyone! I hadn't checked my phosphate in a while and started growing large amounts of (hair?) algae, see video. I checked and it's sky high! A few qs: Where do we think this is coming from? I make my own RO water, could the filters be spent? I'm replacing today. How can I massively...

Hi, Im looking at getting some Trisodium Phosphate to help me dose my phosphates from reading 0 as my SPS have started loosing a lot of colour from what i think is too low nutrients (0 nitrate, 0 phos and my alk dropped to 5DKH :O ), ive used Rany's guide for dosing Potassium Nitrate and sodium...

Hello, I started a new tank on August 17th 2024 using Caribsea liferock as well as about 10lbs of Carib sea ocean direct sand and 5 lbs of miracle mud. I used bacteria and ammonia to cycle the tank which went great. I am carbon dosing the tank, initially I used elimi NP from TM after I added...

Selling my new Trident NP with reagent. Passed the 30 days so I can't return it. I was going to set it up but I decided to hold off for now since I'm going to be out of town for work for a few months. See picture below. Message me if interested. Selling it for $650 shipped.

Has anyone put nitrates and or phosphate remover in their ato water/container? I’m currently using gfo but I can’t get my phosphates low enough, I have some algae starting to grow on the rocks. Also, nitrates won’t budge… I’m not home enough to continuously feed although I do have a auto...

Hi, I’ve recently noticed this type of algae growing on my rock work and sand bed but I’m having issues identifying it. I has am appearance of bryopsis however looking under the microscope it doesn’t appear to look like it, I’ve also ruled out green hair algae as I have dealt with it before and...

Hi all, I’m having this type of algae growing all over my tank, majority of it is growing on the sand bed. It doesn’t look like green hair algae to me, this stuff feels more rough..Please help!

The tank has always seemed to run low on phosphates. i started the tank last may (2023) and i have never been able to detect phosphates using the titration test kits so i bought a Hanna ULR phosphate tester and it normally shows .03. I had a round of Cyano and after a few weeks of no luck i...

Hi all, I know this topic was discussed many times and I learnt a lot from all of your posts. I have my phosphate that is always high, 2 ppm or more as my test kit max is 2 ppm. My tank is 6 months old. I used to slightly overfeed as my nitrate/nitrites were higher than normal threshold but...

Hey everyone I really need some advice lowering extremely high phosphates. Here’s a bit of a backstory (sorry for the long read) My new build is relatively new just a few months. It’s a 125 gallon AIO DIY system , the rock work was recycled from my old 75 gal but it was bleached and then...

My overall system is 340gal and pretty heavily stocked, however I consistently dose Brightwell's 5X Nitrate and Phosphate to keep those from bottoming out entirely. Is there an upside to notching up my Nitrate+Phosphate dosing slightly, and then dosing carbon at the same time? Are there...

Hello all! Tank is roughly 9 months old and my corals are starting to have issues. LFS told me that I would not need to do water changes… Found out that was certainly not the issue. Working on water changes now, it is there anything I should do to get phosphates and nitrates under control...

Hello reefing community, My parameters are: Nitrates 8.5 Phosphates .01/.02 Alk 8 Mg 1450 Calcium 440 I have some few hair algae. My corals look like if they are starving. My question is. Should i get my phosphates higher?

Hi all, recently set up my new tank using caribsea life rock and broken up established live rock. I currently have a phosphate reading of 0.24ppm. Could phosphate be leaching from the life rock? I’ve added around 70g of rowaphos but it doesn’t seem to be lowering. Thanks!

My cat chewed up the pipettes that comes with the Red Sea Phosphate pro test kit. Any idea how many ml of reagents A (13 drops) and reagent B (4 drops) should I add? Thanks in advance. And here is the suspect.

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...

Hi all, I have an Ultra Low hanna phosphate checker but bought the incorrect reagent. Instead of getting the ultra low reagent I got the low range reagent by mistake. Do you know if you can still get an accurate reading using the low range reagents on the ultra low checker? Thanks!
