Help needed

[Ry1]

Hi guys, firstly thanks for helping out, your time is appreciated.

So my corals have been fine and looking super for the past few weeks but now all of a sudden they all look not happy at all. I so my weekly checks and all was fine last friday, is there anything in particular i should be checking.
Thanks.

can you provide your parameters as well as maybe pictures of the afflicted corals and such?

Hi params are:

Ammonia: 0.05
Nitrite: 0.1
Nitrate:1
Phosphate:0
Calcium:400
Magnesium:1160
Alkalinity:8
PH:8.0
Salinity: 1.025
Also worth mentioning is that my tank is only 6 weeks old, and i no now that maybe coral should not be in the tank this early but it was sold to me by my lfs unfortunately and said it would be fine. Which to be fair my coral have been great for the past 5 week.

Corals.

Ammonia and nitrite should be undetectable and I think your magnesium is a bit low

 

[Terry Mattson]

Looks like your tank has not completed the cycle. Ammonia and nitrite should be zero. Magnesium should be about 1,350.

 

[Sheripie]

Also what's your temp? Is it stable?

 

[Terry Mattson]

Try a water change. What salt do you use? How big is your tank? What are your filter systems?

 

[Ry1]

The temperature has been stable at 25c for the last 5 week but has come up to 26.5 today as where i am in the UK is 31c, don’t think the 1.5 rise should be the issue though, and my tank is a 100litre.

And the water is natural sea water from lfs.

 

[Terry Mattson]

Seawater is 1.026. I found keeping it there helps dkh, ph, calcium and magnesium levels. I have a automatic doser. Use kalkwisser and dose 8ml every hour. Keeps things stable. I do occasionaly have to make small adjustments. On water changes I take out about .9 to 1 gallon per day. My tank is a redsea 350, .... 93 gallons. The tank is 18 months old and the key is to keeping things stable and slow changes as needed.

The water I receive is always at 1.025, also is the 0.1 going to put a major effect on the coral? Not sure it would.

I am in Texas, usa. I use fritz salt. Always concerned using natural sea water will eventually bring in pest or man made pollutants.

From 1.025 to 1.026 shouldn't be a problem I think it's detectable ammonia and no2... I haven't try having corals with detectable ammonia and no2.. I'm not going to lol

Yeah i guess there is always that risk, this is my first sea water tank and just went with the recommendation of the lfs, they also seem to sell massive amounts of it so just went along with the recommendation.

 

[Riphter]

Any amount of ammonia is bad. Water changes and maybe some prime. Some dr Tim’s (or equivalent) wouldnt hurt either. Prime detoxify’s ammonia and nitrites but doesn’t remove them. Ties them up for about 24 hours.

I also don't use sea water for the same reasons

 

[Ry1]

I will try a large water change then guys, thanks for the help. Your responses were appreciated

 

[Terry Mattson]

I keep phosphates between. 03 and .1 ppm. Feed my corals, lps and zoas, and a clam once a week. Have 9 fish and 2 shrimp. Use gfo in a reactor to help control phosphate. When my phosphates get high my hammer and frogspawn start to not extend. Took me awhile to figure this out.

Make sure you use rodi for your top off water and if you ever mix your own saltwater use rodi water. My rodi system is 5 stage.
