These are the parameters in the tank rn
7.5 ph low
5ppm nitrite
80 ppm nitrate
2 -3 ppm phosphate
Ammonia 8ppm
I’m sad all the fishes are dead
This reminds me of my first tank.
Tuff Lesson you learned here, but you got the attention of some knowledgeable people here. Not me so much, but them folks with Orange Names.
Something I did a lot of when I was getting started and discovered these forums was click on the build thread badges under peoples names. Check out what they did, and how they did it. Plus ya get to see some beautiful tanks.
One person in particular I think you should read is Paul B. I think most can agree Paul B. has a lot of insight into Reef Keeping. You'll see his thread, tank birthday 47 years.
Ask lots of questions. The only dumb question is the one ya didn't ask.
Bulkreefsupply has a Intro to reefing video series, 52 weeks I think, that is a good source of tons of information, as long as you keep in mind they are also Infomercials to sell products.
Good things happen slow in this hobby, bad things develop quickly. For every chemical solution there is almost always an all natural solution. Before you start dumping chemical fixes into your system research them very well. I have not found an over-night quick fix to anything yet. I am starting to think they do not exist.
Test your water regularly, especially early in your tanks life until you get a fell for how saturated your water gets with nutrients in a given time period. Once your Nitrifying bacteria cycle is established you can leave off ammonia testing. I feel keeping an eye on Temp, Salinity, Nitrates, Phos, and DKH is vital to tank health testing for these every 3 days myself on a 1 yr old system. If you are changing water I see no need to test for Calcium, you're constantly adding fresh levels to your system.
I strive for
81.5 degree F
1.025 to 1.026 salinity (I get a slight fluctuation between 1.024 and 1.026)
40 Nitrate (this number seems to range between 20 and 50)
.08 phos (this is my struggle, it ranges from .04 to .18)
10.5 DKH (This will drop over a weeks time to 8.5, I usually add a little baking soda to the system then, bringing it back up to about 11 or 12.)
I run a bit of a dirty tank, I love Zoanthids a lot and they like water a little nutrient heavy so this keeps them happy. Hope you find your balance, there is nothing that compares to getting lost watching the life in a marine tank.
good luck to you.
