Thanks folks for the discussion and ideas. I was trying Paraguard as a general cure but it wasn't helping after TTM I still had a little flashing. I agree there is a risk I could have a tomont come through TTM in a gill however the fish are QTing for another 8 weeks so I will see if ick returns. I did have a couple of fish that were badly infected with loads of white spots (the wrasse was one of them) and they came out of TTM looking clean and eating well so I assumed the ick was cured (although can't be 100% at this point). Maybe it has just been knocked back but still lingered in a gill or two. I will see if that's the case. I think I need to complete the fluke treatment now. I am just not keen on another general cure because I see no symptoms on any of the fish of any disease or parasite only occasional flash from the gramma and wrasse with the likley cause being untreated fulkes or worms.
My TTM was done following closely the directions given on this site - 2 sets of everything, no cross contamination, 4 transfers with 72 hour hold in between for 13 days. Worst affected fish was my blenny and he has no spots and no flashing anymore.
The prazi that I have is Dicus Fluke Solve because that is the only way I can get prazi based meds in the UK. Here are the details:

Fluke-Solve for killing tapeworm & flukes
Ornamental fish such as discus can harbour a variety of parasites, and often they remain undiscovered until they have been introduced into a new aquarium. This can be a particular problem with fish which have originated from the wild.
Flukes belong to the group of parasites known as Monogean trematodes. The commonest affecting pet fish are the Dactylogyrus species and Gyrodactylus species.
These parasites, called cestodes or tapeworms, are internal parasites which affect a wide variety of fish species including carp as well as aquarium fish such as discus.
For aquarium tanks, again it may be tricky to have a complete clean out of the system, so annual treatment with Fluke-Solve Aquarium will ensure that the fish remain free of these parasites
Stress can also be a major threat to these fish because of the complete change in their habitat and lifestyle, and so any parasite treatment must be efficient and safe - frequent treatments will not only stress these fish further, but can also pose a risk of the very parasites you are trying to treat developing resistance to some treatments.
Fluke-Solve™ is a specially designed fluke treatment for Discus and other aquarium fish. It contains 50% pure praziquantel in a unique solublising presentation.
Comes in a handy 10 grams sachet to treat 2500 litres (550 gallons)
Easy to use - dissolves quickly without boiling or solvents

I rang Vetark to ensure this was ok for Marine and they said it was. I have been advised by other UK reef folk that this is good for marine (not inverts) as well.
I am going to do a second dose tomorrow after a water change and see where I am then. I don't think another general cure will improve my decision making at this point. It does mention a second dose required for hatched eggs and the fact my wrasse "calmed" down for a while before starting to flash again has me fairly convinced some eggs were left and hatched after the first treatment.
Good point about ammonia level in my water. To be honest I haven't checked it and will do but wouldn't I be seeing all 7 fish showing signs if that was a problem?
