nitrate

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...

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...

I’ve been vodka dosing for 3.5 months now on our 80g system nitrates were over 140 and gha was thick 3.5 months later it’s all gone except the high nitrates were dosing 19mls of vodka a day in the morning but the nitrates have stayed a maxing out the Hanna checker at 75+ We do have 9 fish a...

As the title suggests, my phosphates seem to be out of control at 2.0 and I somehow have zero Nitrates. The tank was neglected for a couple years after my daughter was born and essentially went for 2 years with no water changes or detritus removal and very few times emptying the skimmate (it...

I have a question for you @Randy Holmes-Farley I just installed a sulfur denitrator and my ORP has risen rapidly in the last 24hrs. I’ve read your article on ORP and know that nitrifying bacteria can affect ORP. I’m new to this type of reactor but from what I understand the goal is to create...

What Corals do you have in your tank that are the first to indicate your parameters are getting out of whack. For my it's my mystic sunset monti. As soon as phosphates start to rise or things get off a little it starts to retract polyps and the color starts to fade.
