phosphate

This is the refresh of my original 3D Printed Test Kit Organizer Tray thread. The first post showcased now-old designs and one had to dig through the thread to find the new stuff, so a new thread was made to clean things up a bit as the old cannot be edited (Old thread will be deleted/closed by...

I am not sure if this is a stupid question or not but ive have noticed my tank has crazy phosphate spikes after every change. maybe stirring the sand up too much or something? The new water always tests 0 phosphate (i am using hanna) but after the water change it can go up to 0.8-1 which...

I recently created a chaeto reactor for my Biocube. The chaeto is just starting to grow and has made me more comfortable feeding my fish and adding more to my tank. I currently have the lighting 12/12hr opposite the lighting of my display tank. It has been so efficient at reducing nutrients that...

I personally use filter floss because it's cheaper than buying new filter socks and maintaining them but I was wondering what Reefers would think.

Hi Had diatoms a while back and they went on there own….. Then cyano came which I’ve been battling for around a month ish….. I used chemi clean first does 24 hours second dose 72 hours….. 99 % of it went just had a very small light pink patch size of a penny…. That was 3 weeks ago when I used...

Are low phosphate levels bad? Will low levels be detrimental to the growth and health of my corals? Does this mean that I should feed more to my fish? I seem to be having turf algae so I tested my phosphate and it was undetectable to .002 on the salifert test. Lowest level. I tested three...

One never used Hanna Phosphate Checker (HI713) and 50 tests. $25 plus whatever shipping method you prefer unless Boston area handoff. One barely used Hanna ULR Phosphate Checker (HI774) and 50 tests. $40 plus whatever shipping method you prefer unless Boston area handoff. Payment by Venmo...

Hello guys! This is my first post here. My tank is a couple years old, 300 Litre/80 gallon with a sump. I've lost some control the past year due to university and work, but now I am wanting to get back on top of it all. I lost most of my corals over the course of the year, but I still have 2...

Hi, I currently have a large mixed reef system (around 300 gallons) which is currently being monitored by my apex trident (monitoring pH, salinity, ALK, CA, MG). I am just starting to get into SPS, and therefore want to start monitoring phosphate, nitrite, and nitrate levels more closely. The...

I bought Dr.Tims live nitrifying bacteria online and it was sent to me in just a regular box, not cooled with cool packs or anything. Is that okay to use? I have now put it in the fridge but should it have been sent in the mail with a cool pack or something? I am going to be cycling my tank...

I know this has probably been asked and answered 1000 different ways, so please excuse me if it’s frustrating, I am new to the forum and this is my first post, so I’m not up to fully understanding format here. I have a 225 gallon mixed reef, the tank is less than a year old, it is heavily...

Hi there, Recently my sps coral started to bleach, I tested the phosphate and found it was a 1.6. I did a 20 percent water change using rodi water, as well as adding the appropriate number of chemipure blue packets. This dropped my phosphate to .9 however i am at a loss how to reduce it to what...

Hello, I am a new reef keeper, I have a red sea 250 reefer (55g display) that has been running for about 3 months now. Everything seems to be going well, but about a week ago my nitrates reached about 10ppm (API Test Kit), and a lot of brown spots (possibly diatoms) and some green spots started...

My 150g very lightly stocked tank (6 fish and few inverts) is a little over a year old and has never really thrived. While most of the parameters have been fine (Temp: 80, Salinity: 35, Alk: 8.5, Cal: 480, Mag: 1510) I've historically struggled with my pH, Nitrates & Phosphates, and...

I've been battling some cyano and turf algae pretty much since I've been in the hobby 2 1/2 years ago now. About 18 months ago I thought I found the end all solution...that being the Zeovit system. Ever seen then I've been running the full system (Zeo Stones, Carbon, Zeobac, Zeostart, ZeoFood...

I bought the wrong reagent, I needed the 713 instead of the 774. Only 1 packet used. $7 and we split the shipping or pick up in Miami would be awesome if someone had the 713 reagents and do a trade.

I'm dosing a product to assist in sponge growth, which also requires some silicates. Will Phos 0,04 remove silicates? Does the resin have a higher affinity for silicates than for phosphates? Does it have a higher affinity for yellowing compounds, tannins than for PO4 and silicates? Thank you!

Hi new to reefing and was wondering about Phosphate levels. Most places recommend staying below .05 for a reef tank and I am currently at 1.5. I use RO/DI water and Red Sea Blue bucket salt for water changes. I have a new tank with just 2 clownfish and I have only feed one time, frozen mysis...

So my phosphate is reliable between 0.03-0.06, ranging between there month to month. However over the last 4-6 months, my nitrate has been going from 5, to 3, to 1... to now just barely detectable. Why do you think my phosphate can stay so consistent, but my nitrates are diminishing? Any ideas...

My phosphate has been terribly high for the past month hovering at around 50ppb or 0.153ppm. Testing is done using Hanna Phosphorus ULR checker. I finally set-up a fuge in the sump of my RedSea Reefer 170 (43g total volume). Within 3 days of having a large fist size ball of chaeto tumbling in...

Hey all, just have a question regarding my Phospate levels. I installed a GFO about a month ago, when my phosphate levels read at .71, since then, I have brought the numbers down to .19-.22 but it seems that they have plateaued there. I am running a GFO, a biopellet reactor, protein skimmer...

I have been having a few issues with my phosphate level, or I think I have anyway. Both of these test were done at the same time the only difference is that one was done with 16ml of ro water and 1ml of tank water and the other was done with 17ml of tank water. But they both have me the same...

Hi My tank has been running for about 3months now. I am battling green hair algae at the moment. I have tested my RO water (0TDS and 0 phosphate), my top off container water 0 phosphate). Tank water reads <0.03ppm/0ppm phosphate with salifert test kit. I have 4 small fish in 310 litres and...
