Challenge Day 1: Analyze your tank

Albert B Ulrich III 31 Day Challenge 16 Comments

Day 1:

Welcome to the first day of the 31 Days to Build a Better Saltwater Aquarium Challenge. If you haven’t already registered for the challenge, be sure to sign up, so you can get access to the Facebook Group and the Free Resources.

Your First Challenge

Your first challenge is to run away from this giant boulder, like Indiana Jones…


Too challenging? Ok, I have something easier for you. Your first challenge is to analyze your tank. Use every test kit, gizmo and device at your disposal to create a baseline and diagnose what your tank needs the most.

Don’t go out and buy new kits today—just use the tests you already own. After you get the results, be sure to write them  down. Download a FREE Printable PDF to help you track your results.

Do you accept today’s challenge?

If so, please go run those tests now and come back. I’ll enjoy a cup of coffee while I wait.

Ok, welcome back. What do your numbers tell you? Are there any water parameters that are sub-optimal?

…maybe your salinity has drifted, or perhaps the temperature is low or high?

Is your calcium low?

Are you nitrates high?

In addition to running the tests you have available to you, I also want you to spend a moment or two today observing your tank. I know, you probably look at your tank all the time–after all, that’s why you have one, right?

Observe your tank with a critical eye. What are the strongest aspects of your aquarium—meaning, what is working very well? What are the weakest aspects of your aquarium—what isn’t working well? What are the opportunities you have to improve the tank? What are you not prepared for that could potentially devastate your tank?

You know your tank better than I do (of course). While my goal is to inspire, give good advice and to challenge you to improve your tank, you are the one who knows what will make the best improvement to your aquarium.

Determine what the best things are that you are aware of and that you can do today to improve your saltwater aquarium. If you don’t have time today, hold onto that thought–because you can do that task on a day where you don’t want to take the challenge.

Thanks for taking the challenge. I look forward to connecting again tomorrow for Day 2.

What did you decide on? Be sure to share what you’re doing in the comments section, so we can follow along and benefit from your advice and experiences.

    The biggest issue I appear to have is my Alk always stays around 7 dkh…and when I have tried dosing…things die. I can keep nems, inverts, mushrooms, and soft corals…except zoos, those just die BUT palys do well. LPS are doomed in my tank except for 1 frogspawn that is doing great! It makes me crazy! Looking forward to the next 30 days!!

    I have been on autopilot and I’m starting to see some issues start showing up. So, I’m so excited to start this project.

    Currently the fish, and coral are doing great, but had a bad case of dinoflaggelates, that took like 4 months to completely get rid of. Hoping to make sure I prevent things like that in the future from getting out of control.

    Teresa, thanks for joining in on the challenge. Your water parameters look good. Let’s get those phosphates down a tad and I think your tank will stabilize so you don’t get a return of the dinoflagellates!! Thanks for participating.

  11. David Ross

    Thanks to this challenge, I noticed my calcium is a little low at 360. I had a Kh score that seemed high … maybe 13 -15? I think this was calcium hardness or something. Should I be concerned? I’ve read that optimal kh is 9 or so. I’m working at bringing my calcium up. I was only relying on the salt mix to hold calcium up, and it wasn’t doing it.

  12. Susan

    If you have a full aquarium, fish, inverts, and corals, you will need to add calcium. Corals need calcium to grow and I think some inverts need it also as their shells grow. Monitoring is important to ensure adequate levels.

    Ammonia, nitrite, nitrate at 0.
    T: 78,8*F
    PH : 8.0
    Phosphate: 2.5, the equivalent of a nuclear bomb…
    Following the move of the aquarium and its livestock and adding live rock purchased from someone who was closing his tank, phosphate got released after the PH dropped below 8.0.

    Now I have to find a way of getting the phosphate down… Didn’nt move for a week. :c( Any tips?

    Andrea, thanks for taking the challenge and for posting your parameters. Your phosphates are high. If you’re pH is falling, too, that is something to watch. You don’t want to see big swings, because any swing is a big swing. are you using the same salt mix as the previous owner? Challenge days 7 and 8 can help with high phosphates if you want to jump ahead there
