nitrate

So just 2 days ago i preformed a water change as my nitrate levels read at a high 25. I’d say I did about a 45% water change with r.o water. But when I checked again today my nitrate readings are exactly the same? The only thing I can think of is doing another water change, but i don’t want to...

Nitrate increases zooxanthellae population density and reduces skeletogenesis in corals. To reduce nitrates in the aquarium: -Do larger, more frequent water changes -Reduce bioload and/or reduce feeding -Carbon dosing: try a liquid nitrate remover or use biopellets in a media reactor -Start a...

Lately - after a couple items failed and having problems in the past with various algae outbreaks, chemical methods to control algae, etc etc. I've come to the conclusion that 'simpler is better' - So - for my current tank I have a skimmer, some carbon in the sump - and dose 2 part using weekly...

I have a question that I hope someone can answer. I have been cycling my tank fishless for 5 weeks. I have 75 gallon tank using dry rock 90 pounds and live sand 120 lbs. Using a fluval Fx6 canister filter. Also In the tank is 2 powerheads and a HOB skimmer that both seem to be working well...

What is the maximum nitrate reading you know of where corals were kept successfully? What is the “breaking point” for the hardiest of corals? What corals are the most tolerant to high nitrates? Please input especially if you have large predatory fish! Thanks!

We've been cycling a 53 gallon saltwater aquarium for about 20 days now, using a Red Sea Reef Mature Starter Kit for adding the nitrifying and denitrifiying bacteria. Our setup includes live rock, live sand, a protein skimmer, and a biofilter media block. We have been cycling according to...

Setting up to reduce my nitrates which are at 40 ppm and I want to get them down to around 10 ppm. I currently have mostly soft and LPS corals, but tried introducing some Monti's, which are extending but I dont believe they are doing well. Additionally, my Phosphate is high so my assumption is...

Hi all you fellow Reefers, My entry into this fine group was over my Dwarf Seahorse Breeding Pond. There are 750 gallons of Marine Ponds here. With two separate Breeding Corrals and perhaps 100 or so Ponies. It was time to share the methods. The marine ponds are a little too high in Phos for...

OK, so I've been battling high NO3 & PO4 for a couple of weeks now. I've read almost every thread with the same issues, but I can't seem to get any subtle changes for the better. I'm at a loss for what to do. I'm not looking for a quick fix, but I'd love to be able to see *some* changes for the...

I have a order of fish and some zoas coming in tomorrow night. Just tested all my parameters on the tank and I have a few questions. Salinity: 1.0245 Temp: 78 F Ammonia: 0 ppm Nitrite: 0 ppm Nitrate: 20 ppm I kinda wanna get my nitrates lower before the fish arrive. I did a 30% water change...

Hi, My refugium is doing wanders for nitrate levels, but not much for my phosophates, I'm interested in other peoples experience in this regard. My nitrates started to bottom out, so I dosed potassium nitrate to bring my levels up to 3ppm. My phosophate, sits at 0.15 - 0.2. My nitrate went...

Hi all, Im having issues with my 55 gallon tank. 3 of my fish just died. Hippo, Sailfin, and a raccoon butterfly. My tank has been up and running since May 17th. I started with a Midas Blenny and 2 mocha clown fish (added them about 2 weeks after the tank was set up and running a couple days...

After doing a decent amount of research the past few days, I came to realize that running a new canister filter on my tank has seemingly led to nitrate issues. There are only 2 clowns and 1 small blenny in tank, yet nitrates have been an issue. I was unaware that many people label canisters as...

Hanna is about to release the long awaited Nitrate checker, if you check in BRS or in Hanna website, the upcoming device is called HC-HI781. So now my question is what is their rank?

So, we've been trying to reduce PO4 slowly (started the whole process with 0.8) to get more coloration out of our SPS. We actually have a lot of great growth and no algae in our system, which we've been very happy about. We are currently running ROWAphos and Triton Carbon (2 cups each) in our...

Hey everyone! I need some helping solving some water quality issues my tank is starting to get noticeably cloudy. All of the data is below . Cheers! Parameters : Ammonia: .25 Nitrate: 10 ppm Ph: 8.0 Nitrite: 0 ppm Tank and Filtration: 20 gallon Marineland HOB FILTER 1 chemi pure elite...

Hello everyone, I have a question that I might have already figured out but want others input as well. I have a predator tank with sharks, rays, puffers, and a eel. I've been battling with Nitrates for a while and the best I've managed to lower them to is 20ppm with 70% water changes every 4...

So I have been using a API nitrate test since I first started my tank, it has seemed pretty reliable but it has just run out so I thought id try the red sea pro test, bought the kit with phosphate aswell. The issue I'm having is that the API test was saying my nitrates are at 10 but I've just...

So I was speaking to my LFS earlier and they said that my alk could be rising because I have started using nopox to lower nitrates. This sounded odd but what they said kind of made sense and the time frames coinside. So my nitrates where really high at 40ppm before and my alk was at 9.1. I...

Hi Reefers, My tank has been running for almost 4 to 5 years and recently I been having issues with nitrate. Note - I do not overfeed my fish or coral - I will feed them prawn and fish pellets for approx. 2 mins before removing all uneaten food. Currently my water parameters are: Nitrate -...

Hello, I recently have been having a nitrate problem and I told my mother that mangroves could help. She took it upon herself to pick up some seeds from our local lagoon and put them in my reef tank without washing them. I was a little angry, but decided that if anything bad was going to happen...

Hey fellow reefers, I've very new to aquarium hobby and I have a (maybe stupid) cycling question. I've had my tank cycling for past 3.5 weeks and now my Nitrites(NO2) are extremely high(full purple) for past 1 week. I have very minimal to low algae growth. Equipment used. - Dry rocks and Dry...

I know this is not necessarily an emergency but I just added a decent bit of livestock to a 20 gallon cube tank. This includes: - a small Scopas Tang - a Black Snowflake Clown - three various snails - a Tuxedo Sea urchin - a Tricolor Goniastrea Coral Previous to adding livestock to this NEWLY...

I have one tank with lots of xenia growing all over that I have to regularly prune and another tank with no xenia. The tank with the xenia consistently has lower nitrates than the one without. It also seems to require much less maintenance. Is the xenia consuming the nutrients in my tank an they...
