nitrate

Hello fellow saltines, My tank is still young (8 months now) and until about 6 weeks ago I had 0 phosphate and 5ppm nitrate. I started to get some hair algae and instead of just adding some snails I panicked and started doing manual removal by doing daily pulling and siphoning which of course...

So last night I got the High Range Hanna Nitrate Checker. I ran the test and got a 0.0... I figured my nitrates were too high or too low as I am trying to get better color out of some of my corals. I have a 50 gallon IM lagoon AIO with... baby regal tang two clowns tailspot blenny lawnmower...

First time posting on reef 2 reef. Been asking for advice from a Facebook good but haven’t had any luck. I have a 75 gallon display with a 18gallon sump. I have a fuge going, but to me the rites and phosphate are still to high. I had .17 on the phosphate and 17.6 on rites. Done a 20% water...

Hello, I Just began cycling my tank (shrimp method) and as we all know, the standard method for reducing nitrates is to perform a water change at the end of the cycle. Instead, I'm going to run bio pellets in a reactor through the cycle and see if it will help keep the nitrates low. I'm going...

So I've got a Red Sea Reefer 250, but I might be having some issues on the cycle. The tank has been up for exactly a month today. I am currently testing the cycle with API (I have red sea test kits for all other aspects of testing, the API is only for the cycle). My current readings are ammonia...

Hey all, I’m 22 days through my cycle currently, and am experiencing ridiculously high nitrites, so high my Red Sea kit can’t read them properly. I seeded with Dr Tim's one and only, and am testing with all Red Sea test kits. My ammonia has started to drop, nitrites have soared, and nitrate is...

I have a 20g tank and I'm using a canister filter, the issue is my no3 getting high, my no3 reading at 5ppm. In my canister filter, I'm using crushed coral stone, sponges and chemi-pure elite. My LFS recommends using a brightwell purit. Can the brightwell purit really reduce no3?

Hey everyone! I set up my waterbox 20 a few days ago, and added dr tims ammonia and one n only to start the cycle. I dosed ammonia to 4ppm, and have been testing daily. I'll attach a screenshot of my excel spreadsheet with test results. I've been recording ammonia and nitrates from day 2, but...

I should start by saying, I do not have all the answers, in fact, I hardly have any. After combing the forums daily for weeks, I realized that there are hundreds(thousands?) of threads concerning GHA. Unfortunately many of these threads have either gone unanswered, or the answers varied greatly...

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...

Just got some new hanna checkers today and tested high range nitrate. The result was too high to read, and the instructions say to dilute it if that happens. I cut the sample in half and added more water, same result. After a second halving I got 52! This result seems ridiculous as I'd expect...

My clownfish tank since day one has been overrun by green algae all over the glass even after water changes for months and less feeding it comes back within days i need help to what i can do to stop it. Ph-8.2 Nitrate-20 Nitrite-0 Ammonia-0 Salinty-0 Fish stock- pair of clowns, cleaner shrimp, 4...

My corals are not looking so good, I understand at first they might look bad until they are accustomed to your tank for a month or so but it’s been longer all my perimeters are good except for nitrates they are extremely high I have never quite been able to drop them even with water changes I’ve...

I've had my tank up for about 3 years. I got my first corals this summer, and they are doing great. My problems started in September, when school started. I haven't been able to give my tank the attention it needs. I've kept up on water changes, but I've missed a couple too. My tank is doing ok...

Diluted with 5 mL RO/DI so it's giving me 148.8 mg/L! Not diluted but it's in NO3-N which converts to 99.6 mg/L nitrate! I did a ~95% water change on 10/30 so this is pretty surprising. And my 2nd largest fish is in fish jail for being aggressive while my 3rd largest is in the FICU (fish...

Hi there, I am running a mixed reef and recently introduced a batch of new corals. Apparently, in my excitement I have been over-feeding my new arrivals, because after a week I've got a spike in Nitrate to 25pmm (using a Hanna Instruments HI782 Marine Nitrate High Range Checker HC). I normally...

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.

Hello, I’m newer to saltwater tanks and have absolutely loved everything about it. I’m having trouble, and could really use suggestions. I have a Waterbox Cube 10 that is going on 3 months. The tank currently houses a clown, purple fire fish, shrimp, mini conch, and 2 turbo snails. Levels...

How/why would my nitrate swing so much throughout the day? And how to correct it? 100 gallon tank, 4 months old, transfer from 2 year old 40 gallon, mostly softy and LPS, few SPS. I attached pictures of the readings. But at times, I have tested NO3 in the course of a day and it can swing from...

Need some advice, I have no ammonia but high nitrites (1 on a redsea kit) and high nitrates (between 20-50) 32gal tank with clean up crew and 2 clowns. 8 weeks since start of cycle Adding bacteria and prime (using tap water for top offs) I know nitrates aren’t dangerous for saltwater but...

Need some help been a bit confused and can’t wrap my head around this. I have a 30L innovative marine 30g AIO it’s been up and running for about 6 months. Recently I’ve had a bit of an algae break out and my corals don’t seem to be thriving (zoas not fully open.. etc) as they were before. my...
