nitrate

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...

New and unopened. $35 Shipped.

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...

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
