water testing

Hello. Have a Trident NP in the box with new cables and tubes. Getting out of hobby. Works perfect. No reagents. MSRP $669 $400 Shipped Venmo preferred but can make other arrangements.

Hey everyone, I’m looking for recommendations on an automatic water chemistry testing system for my reef tank. I previously ran a Neptune Trident, but unfortunately I wasn’t very happy with the overall experience. It worked for a while, but eventually I started having reliability issues and...

Hello there. I currently use the API test kits (I know...not good), but I wanted to purchase some of the Hanna kits. I am not sure which ones I SHOULD HAVE vs the ones that are not really needed and can still use the API. Any insight would be appreciated. Thanks!

Hello. Are there services where a water sample is sent, tested, and a “cocktail” of needed dosing is sent back to add to the tank? I’m somewhat worried about messing up the testing. Admittedly reading the Salifert directions is a chore. lol. I have a 75gal reef tank that’s doing great but it’s...

Wondering if adding more live/base rock to my reef set up will help get my pH higher than the mid to low 7s that we have. I also am seeing a drop in my alkalinity from mid 8s to mid-high 7s as well. My alk tests at 8.5-8.8 with fresh SW (use Instant Ocean Reef Crystals btw) but later on when I...

Hey all, I have an like brand new Neptune Trident for sale. I used this for 3 weeks to make sure the parameters were correct. I had a Trident before this one and it was always off. This one is perfect and was very consistent. As you can see in the photos, it's basically new. No salt in the...

Tank: Fluval Sea Evo 13.5 Hello Everyone!:smiling-face-with-sunglasses: I am just starting and looking at my first weekly water cycle in 2 days since the addition of my two clownfish and two corals (Xenia and Zoas). I realize that my only knowledge regarding my water is to change 20% every...

This was shipped to me by Neptune directly as a replacement for my unit that flailed, it has not been opened and is still sealed. Had to wait a while for this and I've honestly gotten used to testing manually so I see no need to hook this one up. During the wait I also purchased 6 months of...

Anyone currently uses this machine for water testing? Any feedback to share after long time use and accuracy of product

Let’s get a real time look at what a small pico tank looks like if you neglect it and don’t do your regular water changes. I’m going to test it today with my Hanna and than do a 50% water change, wait an hour and check again. I’ve been pretty busy at work and haven’t done a great job taking...

Been using a Hanna pH checker for over a year and have regularly been getting readings of 8.6+ (8.6 flashing on screen). If I put 20-30 mL (have a 20g nano) of some white vinegar in the tank, usually will bring the reading down to 8.3 or 8.2. However, recently got the Apex A3 Pro and have had...

hey saltwater fish gang, i was just wondering how inaccurate is the API testing kit? i have a fish tank that i’ve been testing with API but I’ve read from past experiences that Ammonia is usually super inaccurate, but what about the rest? PH, Nitrite, and Nitrate? are those a bit better? I...

Hello! This is my first post and my first reef tank. my tank is 2-3 months old and I have diatoms all over the tank sand. When I siphoned it during my last WC, it came right back. Most likely it’s just the ugly phase however I’m wondering if there’s any possibility it could be my water. The...

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.

Hello! Thanks for stopping by. This is my mandatory "dumb" beginner question :) I have just gotten my very first marine tank wet for the first time to do a leak test and she has passed with flying colors! Now, I need to make some more RO DI water for the cycle. I have quality salt ready to mix...

I started a 40 gallon AIO on October 27. Water from LFS. Live sand and bottle bac as instructed, and a couple of cap fulls every 4-5 days until gone. Tested water yesterday before my first (5 gal) water change. Tank looks great and I want to add a few corals if we are ready. Used API tests and...

I'm a bit overwhelmed by the number of Hanna Checker for phosphate. I've opened a poll to see which one you guys use. Could someone correct me if my understanding of these three checkers is wrong? And maybe suggest which one I should get? The HI774 sounds like the best choice for someone who...

With the risk of sounding somewhat foolish, I think I am over/under thinking water testing. I have a 20g that has been up and running for about a year now, and im pretty sure im not testing as much as I should be. I do 5g water changes every 2 weeks, really have no big issue with algae (with the...
