nitrate

Keep having a lot of detritus staying and sitting on the live rock. Any time i try moving the rocks all that detritus floats into the water column and back into the rocks. I know dead detritus on live rock can be both bad for nitrates but beneficial for bio media on the rocks as well. Only...

Hey everyone! I’m new to the saltwater side of the hobby and wanted to share my journey so far—plus get some advice and reassurance from the pros here on Reef2Reef! I’ve been keeping freshwater tanks for a while, but about 3 weeks ago, I finally took the plunge into saltwater and set up my...

My tank is about 3 months old. Moderately stocked 55 gallon reef tank with 29 gallon sump. Stocking list m: 2 clowns Sixline Wrasse Royal Gramma Tonini Tang Mixed corals. Softies, LPS, SPS Sump Filter Sock (changed ever few days) Refugium with chaeto and AI Fuge light running opposite of...

I’m sure this question has been answered a bunch of times, but I'm hoping for some help with my nutrients. I have a 40b with a diy AIO that’s been running for about 8 months. It was set up with rock, water and sand from my previous tank to speed up the maturing process. Current stocking is two...

Hi all! Long time lurker here, but the first time I'm posting. Long story short: I run a mixed reef setup with 20+ years old live rock and my nutrients keep bottoming out, to the point where my pulsating Xenia has all but disappeared and GSP won't even open. SPS are growing fairly well, to the...

Guys I have a big problem and I can't find an answer. This is the situatio; The tank is a 33G Cube with a sump, it has been running for almost 3 years with only a pair of clownfish and a purple dottyback (pseudochromis Fridmani). I started with Ocean Direct Sand and dry purple rock from...

Hey all, newbie here. Hoping to learn what's possibly going wrong (if anything) with my current attempt to pre-cycle some caribsea life rock. I've got them in a 10 gallon brute, 2 wavemakers running for circulation, heater at 78, does Dr Tim's ammonia to 2 ppm, and added 1 oz of Fritz 900...

Hi to you all. I am from the UK and have used a 500g tub of sodium nitrate for the last 3-4 years to increase nitrate concentration when needed. That tub did me well, but now it's running out and I need a replacement. Try as I may, none of the companies that offered this for sale are still...

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...

So I cycled this tank recently and did a 50% water change followed by a 70% water change then left it a week and checked the levels again ammonia 0 nitrite 0 nitrate 100after both 50% and 70% so did a 80% last night checked the nitrate this morning still sky high for back story fluval flex 34L...

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...

I have 3-year-old 20 gallon nano with mixed LPS and SPS. About 6 months ago, my tank was matured to the point that 0 nitrate and 0 phosphate can be read with my Hanna checker. Then, I had a crash (probably due to the low nutrients and low iodine) and quite a few torches and hammers died. After...

Hi everyone I just tested my tank last night my ammonia was 0.45 and my nitrate was 20.5 also just had fish in it for about a week. I was planning on doing my first weekly water change on friday. Do you think I should do it sooner?

Hello I’ve been cycling my 40 gallon tank for more than 2 weeks. My ammonia has been around 0.25 for the past few days while my nitrite has been 0. My nitrates is 2.5 and it’s slowly going up 0.1-0.3 everyday. Is my tank ready for fish and should I do a water change?

So as the title says I did about a 20% (5 gallons) water change last Sunday and tested nitrates on Monday. They came out around 13.9ppm which was very surprising because that was slightly higher than they were before the water change. I left it at that for a few days and tested again and came...

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...

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...
