parameters

I've heard about the problem of Hanna's Magnesium colorimeter reading high and recently learned that you can fill out a form on the Hanna website to get them to send out a new Reagent to correct the issue. But has anyone not had to do this and is getting similar results to other tests they do? I...

Hey guys I’ve been doing saltwater for 6 years now it’s been through a Fowlr system, a shark tank with soft corals and now it’s full of tangs and other reef fish along with inverts. It’s a 180 gallon tank that I believe has been well established I have soft corals and bubble tip anemones in it...

Hello, all! I’m from Central Alabama and recently started my first saltwater fish tanks; the first is 20 gal and has been running since the start of March. The second tank is 75 gal and was started a few weeks ago after I got the hang of water changes, testing the water, and getting used to...

I was wondering if there was any Salinity testing equipment that actively reads Salinity in real-time, I use the Hanna Salinity Checker which I really enjoy but sometimes I get the feeling that it's not as accurate as a Refractometer.

Hi all, This post is me being selfish and wanting some advice on how to get better practices on my husbandry and overall more knowledge on this wonderful hobby we all love. I’ll be going over my lighting, parameters, equipment, water change process, and livestock I have in my 20g long nano...

I asked Neptune about my trident being off from other test kits and they told me I have to test the test kits to the calibration solution that is provided by Neptune in the trident dosing solution to compare how off they are to one another. this seems very logical and a way to calibrate your...

So I just got a new pack of Tropic Marin classic salt. Its dKH is supposed to be 9-10 dKH, but when I mix it up it comes out to be 14 dKH!!!?!. I mixed and tossed that bag around when I first got it. Ive made two batches with the same results. I measured and used the correct salt portions: ½...

Hi All, I am relatively new to Saltwater and would love some assistance with my current situation. I was a little excited with the cycle and did have lights on including white for some time ( I have learned since then). Can someone please assist in identifying the algae growth and let me know...

My tank currently consumes 0.2 dkh per day and roughly 10 ppm Ca and 10 ppm Mg per week. I use Red Sea Coral Pro salt which has 11.5 dkh, 450 ppm Ca, and 1350 ppm Mg. Without a water change during a week the dkh would drop by 1.4 along with 10 ppm Ca and Mg. Is this fine if the water change is...

Hello, So I have a 25g JBJ Biocube. It was doing pretty good until recently. Been having issues with Phosphates and Alkalinity. So I’ve been going to the LFS weekly and having them test everything. Asking what I should do or not do. I went in yesterday expecting my Alk to have dropped and it...

I have a 25 gallon tank that's going on 7 months old now. I just recently have been tracking my parameters more regularly, along with feeding and water changes. I have a small refugium with chaeto, and codium macro algae and mangroves in my main tank that may influence NO3 and phos. For corals...

I have no idea why my digitata montipora is bleaching (photo 4). My RBT (photo 5) has no tentacles and is hanging upside, it has been on the decline since I brought it about 7 weeks ago. The second green micromussa polyp is bailing out of the skeleton as well (photo 1). The first polyp bailed...

They appear to be closed even though lights been on for hours, I will check water where is at the end of the week but I was wondering if anyone had any ideas as to what was wrong.

Hi everyone, I just bought a bunch of cerith about a week ago. Since I’ve had them they all hang out right at the water line. Almost looks like they’re trying to escape. Tank temp is 78.7-79.0, haven’t had a chance to test my water but everything else (fish/coral/exsisting CUC) are doing...

Hi everyone I have been looking after my fish and coral for about 18 months now. I have a 180 gallon 6 foot aquarium with mostly lps and softies, I tried some sps but only the montipora has been growing and doing well. After this time I would imagine my tank should be stable enough that...

After being successful with a FOWL tank I decided to take it a level higher and make it a reef tank. I started with KENT MARINE NANO CORAL A AND B and VIPRASPECTRA 165W I dosed accordingly and only once since starting this tank, I want to say a month ago. Im currently still using Instant ocean...

Last week I ordered coral frags and decided to start my reef tank in my 29 GAL which was FOWLR before. Now I knew nothing about reefing or the chemistry but taught myself while waiting for my corals. I set my reef tank up and used Kents Nano Reef A&B to start up the tank. However After using Red...

I have a 125g aquarium, with a fluval fx4. It has a carbon filter, some filter floss(mostly for catching the diatoms), and seachem matrix media. I have a Coralife 125g protein skimmer that still has microbubbles for about a month now and it is pretty loud, but does produce skimmate. I have some...

My alk is at 17 dKH and I was told a water change would fix this. However, after changing out about 5gal from my 20gal tank, the alk stayed the same. I’ve read in other threads that some people suggest acid, but others heavily warn against it. Is this a problem I just have to wait out?

Hi everyone, I have a 20gal tank that I've modified to keep it an all-in-one tank. I started in late February of this year and it's going really well. Since started it's been cycled and I have added a Turbo snail/Emerald crab, then waited a few weeks before adding in two clownfish. Livestock is...

Hi everyone I’m having some trouble reading whether my ammonia is at either 0ppm or 0.25ppm. In person it has more of a green hue but it has tested this color for about a week now. My nitrite is at 0ppm. I’ve attached a picture with flash and without flash. What do you guys think?

For the past 2 months, I have been dealing with slow tissue necrosis (STN) on many of the SPS in my tank. Multiple mini acro colonies (~4 in) have bitten the dust and I cannot figure out what is causing it to happen. Also, some SPS frags were also affected by STN while just one of them succumbed...

New to this forum or any forum. First post 3 months in the hobby. Anything look wrong with my parameters? have abit of coralline growth , the spike in orp is after extreme removal of 80% GHA on and in the crevasses of my live rock. Any tips are apperciated . Thx Gif Below Idk how to add it to...

Hey guys, I really need your help. I am a mechanical engineer tasked with designing and configuring a self-regulating Saltwater Aquarium but unfortunately I know nothing about aquariums (Well, not true, ive been reading up a bit, but id still consider myself completely ignorant on the subject)...

Hi reefers, I am in need of some serious advise, I am new to reefing so learning the ropes, but basically I have a very bad problem with a very high alkalinity level. To give you some information on my setup, I have a Fluval 57 tank, running on OU water and Red Sea salt for SPS dominant...
