nitrate

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...

Hi. As the titles says, how would you guys dose potassium nitrate to raise nitrate levels? I am currently having a situation here, after some research Ive found out that my tank is "nitrate locked". I have 0/undetectable nitrates and 0.5 phosphates, which is high. Im planning to add SPS soon so...

So I made the rookie mistake second time around and picked up the API master saltwater test kit. Here is my nitrate reading and not sure where it lands. I think it’s time to ditch it. Any one have a recommendation for a trustworthy brand? Thanks in advance.

I current have 1 CBS and 10 cerith Snails in my display that I have begun to fallow. I have some Coraline algae in there too. I'd like to eradicate my spionid worms aswell, but in order to do that I'd need to have no food come to the bottom. Another thing is if I have no nitrates...won't...

I have just been testing my tank for nitrate and I am now not sure which test I should trust. I have used a red sea and a salifert kit, the red sea kit said I have Nitrate of 36 ppm and the salifert said 2.5 ppm. Everything else in the tank is testing fine just the nitrate test that is the...

I made a large water change today, and thought'd it be "fun" to compare results between the new Hanna Nitrate High Range 782, and the old Low Range 781 using the dilution step. 781 Low Range diluted 782 High Range Percentual Difference Before Water Change 24,9 33 27,9% After Water Change...

Selling a Hanna Nitrate Low Range never used, I am too lazy for that many steps plus my tank runs always 10+ nitrates. $35 shipped. Thanks

Really confused about a couple things. First I did a water change in my 45 gallon tank after I notice I have no nitrite ammonia Is .25ppm which I read means 0 since it’s an ati test kit. My issue is the nitrate is light orange so in between 10-20ppm. Second day I checked and still hasn’t really...

An excellent paper: Integration of Marine Macroalgae (Chaetomorpha maxima) with a Moving Bed Bioreactor for Nutrient Removal from Maricultural Wastewater My takeaways from it are: - We should give up on creating anaerobic denitrification (like with ceramic blocks of filter media) - We should...

Need help with Red Sea nitrates results. I’m am leaning towards 20 but it can see some 50 In it. Any thoughts? All pictures from same results

Has anyone had any experience with the aquarium systems seatest test kits? any reviews/experiences? cant find anything on them, my LFS recommended them but im getting "odd" or just unexpected readings and dont know if i 100% trust them yet. Im using the ammonia, nitrite and nitrate test kits of...

Okay everyone I have run into an interesting and difficult predicament that I think I need more information on. So I have two tanks. Let's call them Tank 1 and Tank 2. Both tanks have been running for one year, both tanks have their own filtration systems with exactly the same equipment, and...

Hello. I’m currently at the end of the cycle for my tank. Ammonia is trace and nitrites have risen and are now nearing 0. Nitrates were at 25 ppm so I’ve done a 25/30% water change today to lower it somewhat. from advice on here I have added my first fish today and all appears to be healthy...

Hi, Im about 3 months into my nano reef, I managed to get amonia nitrite down to 0 and nitrate down to 0.3. However, I added a hammer coral and 3 blue leg hermit crabs after this and now im seeing small signes of ammonia (total ammonia). Nitrite is above 1 as per the tropic marin test kit and...

Hello. I am currently in the process of cycling my Red Sea Max Nano reef tank. I've added 20lbs of Carib-sea special grade live sand and about 15-20lbs of Carib-sea Life rock shapes (spored with bacteria). I've also added a mesh bag worth of Fluval bio tubes (for surface area for bacteria)...

So up until a few weeks ago I was battling high phosphate levels 1-2ppm, nitrates never rose above 10ppm, usually were at 5ppm. In an effort to lower PO3 I reduced feeding to once a day, that helped a little, got down to .5ppm. After a few weeks of that I decided to dose some Fritzyme 9 and...

Hi all I was just looking for a tester, one that was better than the Hanna ULR Nitrate tester and found this. Does anyone have any experience with these or anything similar? Compact Nitrate Ion Meter LAQUA Twin - NO3-11 Product code: NO3-11 Compact Nitrate Ion Meter LAQUA Twin, compact meter...

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...

Hello all! I have a fluval 13.5 and ive been following the complete Red Sea recipe which ive attached below, im giving 4.6 mls of coral AB+ mixed with a bit of reef roids (usual target feed but sometimes spread throughout the tank) and 1.1 mls of nopox, plus running the coral life 2.0 skimmer...

With daily auto-water changes, i've not 'manually' remove water from my system for a couple of years. Have some dead areas in the bottom of my sump that have collected crap, going to stick a powerhead in there to keep things in motion going forward but about to get in a vac it out. Any reason I...

The nitrate level on my tank is below .1ppm. I have been dosing the equivalent of 1 ppm sodium nitrate for a few days and every morning I test its back around 0. I tested minutes after dosing and read around 1ppm and I even dosed to my water change bucket and got 1ppm. So I am pretty certain my...
