Hi all,

I have been in the hobby on and off for 40yrs or so breeding and showing mainly freshwater fish and as a specialty Chiclids. I decided after some reading to try Marines about 2yrs ago now.

I moved and my ability to have four 4' tank set ups and multiple tanks and show tanks to a miserly 100 litre tank mainly due to the house build and lack of space.

I have had my tank set up now for almost 2 yrs and my efforts produced great results until about 2-3 weeks ago. I bought the Reef Seney system and thought this would be able to be a second eye on my system (partner has no idea apart from that's a pretty fish...dragon wrasse)

So I have a small set up, 100 litre Askoll tank with a ocean-free-hydra-40-internal-filter-and-depurator and a hydra 20 as well as the internal Askoll XL tanks internal filter so in all we have in excess of 1000 liters per hour of filtration in my 100 litre tank. Lighting is managed by an Aqua Ray reef system. I also have approximately 20lbs of live rock and live Caribbean sand

inhabitants of the tank are

2 x clown fish
1x sail fin tang (not an addition of mine)
1x blue neon cheek goby
1x 6 band wrasse

all were small fish at the time, I was away when the tank was stocked but they all lived happily for a year until 3 weeks ago

I had 2 cleaner shrimps and 2 Fire shrimps they died and were removed, all apparently healthy until they passed.

Now the Ammonia issue has occurred in the last 2 weeks I have a seneye reef unit monitoring the aquarium and it shows now 0.072ppm Ammonia this has risen in the last 2 weeks from 0.001ppm.

Tonight I have performed a 30% water change and with all the filtration I am at a loss as to why now there is a major spike i.e 0.076ppm Ammonia.

So what do I do? Strip down the tank and get rid of any live rock or and Zoa's and have a small fish only or is this manageable at almost 1000 litres per hr filtration.

Any ideas..
 
First of all i would follow up with daily water changes without exception until ammonia is back down.

Is there any other dead cuc maybe that you haven't noticed such as snails?

What is your filtration set up?

And I'm sure you're aware that that sail fin tang shouldn't be anywhere near a tank that size. So i would definitely look at passing him on and getting something more suitable.

I haven't used Sen eye myself but i believe you can speak to them over the phone to discuss readings?

Sorry I missed the bit with your filtration. Is there any chance something might of got into one of the internal cartridges and died?

When tests show truly bizarre results, the first thing to test is the test itself. Get another test, eg Salifert Ammonia test or even API test strips, and see what it says.
 
Let me ask this..
Pretend you didn't have the seneye and look at the tank..
What problems do you see with your eyes?

And when was the last time you cleaned your filters or replaced them?

In general less than .1ppm is basically harmless to most critters..
And heck.. Who's to say the seneye is even accurate? Have you gotten a second test result to back that up from another source?
 
Reef Chief, Nothing has died in the filtration system, I agree re the sail fin but as I was away when this happened we rolled with it, in fact he has been a perfect tank mate. No aggression and at only 2.5" I think we have decided all ok at present, he has a home when he gets bigger.

The issue is why has my NH3 increased so much? regular water changes 20-25% per week.
 
So 100 liters, that's only about 25 gallons I think? I think maybe your bioload is catching up with you as the fish grow. I think you can manage the immediate problem with water changes and the advice above, but ultimately that sailfin tang isn't going to last in there. Rehome it and hopefully things will stabilize again. Good luck - it's stressful to have tank issues I know!
 
Are you running bio pellets in those filters? Sometimes they get clogged, or, have you made any drastic filter changes recently?

If you're afraid for the creatures, then dose with bio spira as you look for the root cause. I had a sailfin in a 20gal once, it got ich, my pep cleaned it, I took it out and my nitrates went down. I was very novice and the tang grew very fast!

Good luck! :fish1:
 
I just watched a video that may pertain to this question. Ifv you're using a bio filter in your canister, if they dry out - say from a power outage or mis handling during maintenance - there can be an amonNia spike.
