Operation Marine 2.........now 3

Your rocks will leak Nitrates for a while after you have moved them as well it might just be a matter of adding some purigen and watch the results try not to rush anything or add a few solutions at once as you might add a diffrent problem :good:

I managed to get my biopellets just waiting on my reactor now will post results as it goes along alothough I am not sure how will it will go as my Nitrates are 10 and phosphates are .003 if I got these to 0 or untraceable on test kits I would be happy but time will tell :good:
 
At the minute I'm on a once a day feeding routine to try and gain some stability at least, along with large water changes . Once it's at a lower and stable level I will then test a variety of different theories and hopefully find the cause.
 
Hehe I am lucky I only do a 10% water monthly as my nutrients are lowish and I use heavy metals with my balling :)
 
Tested water before work last night and nitrates were still shown over100ppm on chart purigen has been in 24hrs by then (2 pouches @100ml each) enough to filter twice my tanks volume. When u test any other source eg ro salt mix etc I'm gettin 0nitrates so think it can't be a dodgy kit. Goig to test next water change water when I get in this morning before adding to tank to quadruple check the result if that lol.
 
Water change tested 0 nitrate again yesterday, tested tank just now and it's showing 100+ppm still even with purigen running. These nitrates are not moving. I am beginning to consider taking everything out scrubbing rock in saltwater and putting back in tank with fresh saltwater mix
 
What an earth is going on :blink: could the rock have come from a very high nitrate tank and it be leaching?

Original rock came from swallows in colchester and was fine, it was running in my small rio180 for 8montha or so before going into the big tank where it ran for many more months until i added the rock i got from a reefer who closed down his tank. It all seemed good was kept in his 6ft sump tank with flow and heat no bio load on it as all stock was gone hence being in the sump as main tank was empty.

Unfortunately i hadn't tested water for a while before adding that rock, in hindsight it would've been an idea to maybe quarantine that rock for a week or so and test parameters.

Does anyone think i am over stocked?

I am seriously thinking of buying a new bubble magus skimmer(for future upgrade) and taking stock and rock out. Putting some rock in a couple large containers with livestock and skimming etc then refilling tank with fresh salt mix reintroducing some rock and stock slowly. Seeing what happens that way. Only trouble with that is would have to remove sand bed which will impact my mandarins diet, although he eats frozen it's always going through sand eating pods etc.

I really am running out of ideas fast
 
Run through the stock again please and you did put in new sand didn't you when you set the 400 up?

Stock is as follows

1regal tang 4-5"
1yellow tang 4"
2 percula clowns
5 chromis
1 copperband
1 mandarin
1false gramma
1flamehawk (small)
2blood shrimp
1peppermint shrimp
Cuc has been decimated by my killer hermit not sure what remains apart from a few ceriths, nass snails, 3turbo snails.

Used all new sand in the 400 seeding with half a cup of old sand
 
Here are a couple images of tank as of today

As you can see those mushrooms and zoos are fully open and always are and that space is in-between my two structures a cave on right and bombe on left.

The only bad cyno i have in on the second image and a film on the rhs pain of glass but nothing major. Have noticed a bit of hair algea cropping up but nothing major again and thats from where cyno has been removed by syphon.
 
Have done some asking around and been told basically my tank cannot handle its bio load, basically overstocked. Finding this a little odd as only large fish i have are the two tangs, yes i know they are waste monsters but the remainder of stock are not.

Have basically tow options. Add a sump and wait it out until a DSB establishes thia ia a lot of work and means holding stock in temp homes for a week minimum.

Or lower stock levels which wife has said would mean shutting tank down end of conversation, as she doesn't want to lose any fish.

Have been given an ultimatum of moving a radiator and removing a breakfast bar and getting a second hand 5x2x2 system with a compromise on colour to go in the dining room. Trouble with this option is the same as sumping current tank DSB needs time to establish, and cannot run tanks side by side.
 
Ordered 500ml of NP Bio pellets should get them tomorrow, going to run them in my deltec FR509 reactor and place outlet next to slkimmer intake in tank. Not sure exactly how going to set this up and it's not a HOB style reactor may need a serious pump to turn pellets over enough and also get water back to tank unless i can stand reactor at almost tank level somehow.
 
Bio pellets arrived, very tiny things so going to have to mod the reactor to stop them going through the dispertion plate at base
