The NO3 is not the real problem, the P04 level is more problematic. Do you vacuum the sand regular with each water change ?

Can you please also tell me something about the fish you keep in the system (sizes / quantities)

I do vacuum the sand bed.

I have quite a decent bioload from the following:

1 x Clownfish.
1 x Matted Filefish.
1 x Cleaner Wrasse.
6 x Scribbled Anthias.
1 x Powder Blue Tang.
1 x Purple Tang.
1 x Yellow Tang.

3 small feeds per day and some nori every couple of days.

This is actually two fish less than when I started the thread and an additional marine pure block and at the time of starting this thread I had zero nitrate and it didn't seem to matter how much I fed, nitrate would not shift from zero. Nitrate seemed to increase at the same time as trying to reduce Phosphate and possibly leaving it too long before a stones change.

As I mentioned, the Phosphate turned out to not be as high as my test kit was showing and was in a suitable range. Lesson learned about trusting my eyes more than the test kits as the corals were really taking off when I tried to 'fix' the 'problem' that didn't exist.

It seems that the balance in the tank was lost when I started messing about with things and that it has still not regained a balance.

I wonder if additional Zeobak would help. Currently 3 drops twice per week.

I'm going to send off another ICP test shortly to see what Phosphate level they detect comapared to my Hana ULR kit.

Thoughts? It's easy to say the bioload is too high but there is twice the capacity for bacteria (additional marine pure block) and less fish compared to when Nitrates were zero and I couldn't raise them regardless of how much I fed. The tank would therefore appear to be capable of dealing with the bioload and it must be an issue with balance being off. Perhaps some use of Agent Green (mild Lanthanum Chloride) to get the Phosphate levels down and hopefully the tank will then be put into a more balanced state and be able to deal with the bioload on it's own again?

Perhaps more than recommended Start3? Then again, I tried half the recommended dose for a while and Nitrate levels didn't increase (but Phosphate did).

I do not have additional ideas at the moment but it should have something to do with the balance of biology. I am still thinking it might have something to do with the blocks but I have no experience with them. Filter sponges for example do also increase NO3 over the time, maybe a similar situation ?

It must be something off STILL with the biological balance.

It's possible for blocks to retain detritus and produce nitrate but I have rinsed the older one thoroughly and the second one is quite new, plus I have a roller filter placed before them.

Perhaps more regular Zeobak?

Increase Start3? Carbon dosing usually says to increase until nutrients are under control, whereas Start3 gives a maximum dose based on water volume. Can it do any harm to increase the dose a bit and see if it helps, as I would with any other carbon source such as vodka?

If you like to dose 1 drop ZeoBac / 25 US gallons every other day for some time it will not cause trouble. You can also try to increase ZeoStart to lets say 20 – 25 % more than the recommended maximum which is 2 ml / 300 US gallons daily, increase it slowly step by step.
