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...

I'm a bit overwhelmed by the number of Hanna Checker for phosphate. I've opened a poll to see which one you guys use. Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get? The HI774 sounds like the best choice for someone who...

While phosphorus is important for the development of livestock, it can be risky for aquaria occupants, especially corals. The perfect level of phosphorus in saltwater reef aquaria is 0.02 - 0.03 ppm. How Does High Phosphates Affect My Aquarium? -High phosphate induces Algae Growth. When Algae...

I’ve been struggling with keeping my phosphates under 1ppm and was wondering if I should try harder with doing water changes more frequently as in twice a week? Or should go to get a phosphate remover? Both my tanks have HOB equipment if that makes a difference with anything. I will post my...

Hi, i just tested my water with API reef kit yesterday and my phosphates read 10 (not 1.0, I am not mistaken). I've been running some chemipure blue and it looks like that wasn't enough so I added some chemipure elite and the algae growth has slowed down a bit since adding yesterday. Is this the...

So I come down to make coffee this morning and find this happening in my QT tank, PO at .5ish tested twice Ammonia: 0 Nitrite: 0 Nitrates: 10 Ca: 415 Alk: 8.3 Mg: 1230 Gonna do a water change, probably head to the store today to grab some phosguard. Any other suggestions? Should I pull the...

OK, so I've been battling high NO3 & PO4 for a couple of weeks now. I've read almost every thread with the same issues, but I can't seem to get any subtle changes for the better. I'm at a loss for what to do. I'm not looking for a quick fix, but I'd love to be able to see *some* changes for the...
