water chemistry

Over the past two months I have added another tank. My first tank was my biocube 32 which I fell in love with the hobby. Tank is doing great and decided to get another tank. Ended up with a reefer 300xl and have been having a blast setting it up! New to the sump world which I’m enjoying the...

Hey all, I have a 10 year old BRS DELUXE 6 stage RODI system. I added a second membrane for saving water a few years ago. Recently, I moved to a house with amazing water pressure and got 2xmembranes 100GPD. so now I have 200GPD. My TDS incoming from the city is 38. the water coming out of the...

The tank is a reefer 350, been up and running for 14 months, first corals added about 3 months ago. So recently I’ve changed salt from Red Sea blue to Red Sea coral pro(red). And just realized that the dhk of that salt is around 11.5-12. I plan on doing frequent water changes to bring my...

I am writing to you all because I would like to discuss what I believe algaecide has done to my tank and figuring what to do now. Let me first begin by explaining my hypothesis as to the reason that drove me to use API Algaecide in the first place. The Algae Bloom 1. I introduced ~15 Mexican...

I mixed some SW to QT an incoming fish but turns out I won't be able to get it until next week. I know I could just let the water sit there until then but I was just about to start a phytoplankton culture soon so I'm curious if I could boil the water (to kill any live contaminants) to use for...

I have an AIO mixed reef with fish by Waterbox. 50.3g. I turned the filter off last night at about 8:00 p.m. to feed and dose phyto. ...woke up this morning to a cloudy tank... Only then to realize that the filter had been left off all night! 12+ hours. Somehow temperature is still reading 78...

1st test - 13th oct was 1.1ppm (hanna nitrate HR) 2nd test - 27th oct was 0.1ppm (hanna nitrate HR) I haven't done any water changes, no carbon in sock, skimmer has not been running. I even added 5 new fish after reading 1.1ppm. Have also been heavy feeding and using reef energy plus. Any...

getting the Salifert Reef Testing Kit for now, but if there is one that just makes life much easier I would like to get it.

Hi All, I’m having big issues with my Trachy all of a sudden. I’ve had this coral for about 4 months now and up until about a month ago it has always been blown up and inflated and happy. I first noticed what I thought were eggs, fluorescent mucous like deposits. (Found out this was just the...

A few weeks ago, I dosed ESV B-Ionic alkalinity and calcium. I used half the recommended starter dose and my alk went from 8 to 20+ on both the Hannah and Red Sea titration test. I did water changes to try and rectify the spike, but only made it worse using different than normal salt. Alk...

So I have a 32 Gal Fluval Flex that has been running for about 9 months now. Recently, I had a couple Zoas and a GSP that have been closed up for a few days so I decided to test my water. The results were: Ammonia: 0.0 Nitrite: 0.0 Nitrate 0.0 (checked twice w Hanna checker) Phosphate:0.37...

So I have not dosed any Mg in the last month and a half, all the products I use to maintain the tank does not contain Mg. Anyone experience something similar before? Kh is being consumed at around 0.5 every 4-5 days. Corals are medium load 95% softies 38 gallon. APR Mg 2 3 1350ppm 5...

What's the longest anyone had to wait after Triton received your sample for the results?

I know that there are multiple write ups on using old tank water but I would very much appreciate situation specific advice if you folks don’t mind. I’m moving my 2’ tessalata eel from his current 55 long holding tank to a 90 gal 4’ x 2’ x 18” (L x W x H) with sump (sump is about 25 gallons)...

Hi guys, I have been scouring the threads for awhile now, in search for potential solutions. This is my first post and I have finally decided to ask for some help. I have a 180 gallon reef aquarium I bought second hand. I have owned the tank for about 2 years or so now. I started with wet rock...

Hello, I have 2 clowns currently in my new reef tank (3 days old right now). I am using the ATm coloney method for cycling the tank. I have done a water test today that shows 1.2 ammonia, no nitrites but 0.2 ntrates. Is this right? As I am concerned the amonia is going to cause harm? Any help...

Ive posted here before and Im sorry if im taking too much of your time guys but youve been really helpful. Brief background behind the question is that my bachelor thesis is about designing a smart aquarium. **Some more elaboration on the question:** It doesnt really make sense to have 20...

Hello - First post in this community and newer (6 months) into reefing. Sorry it’s so long...About three weeks ago I setup my second tank, a 70 gallon tank with a 26 gallon sump. Based on BRS’ recommendation, I decided to set this tank up using HW Marinemix Reefer salt. For some background, my...

Hey, I recently had a problem in my tank. It’s about 7 weeks old but it was going really well and I couldn’t really tell what had happened. All my corals were open but after i did a 20% water change they all closed up and none have opened back up since then. I thought it might be that one of...

I am wondering if anyone has any recommendations on why my LPS and zoas are showing very slow growth. I have a Fluval Evo with an AI prime light. I just got Seifert tests in the mail today to test all my levels. I am currently dosing 2 part 1.25ml of B Ionic 2 part. This tank has been running...

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!

I'm in need of chaeto for my refugium but all my LFS are out. Trend is consistent with online stores such as LiveAquaria and Algae Barn. However, does anyone know of another online supplier that sells clean/pest free chaeto? What are some other macros algae to consider for my refugium? Its...

Need help figuring out what to do on my next build and what equipment to run. Currently I mix kalk in a 5 gal pail then transfer it to my ATO. It keeps my Ph, calcium and alkalinity stable. I’ve been considering a calcium reactor but my pH is already low 7.8 and I’ve heard they can lower pH. Can...
