Trouble In Fry Tank

[Nexorcist]

Hi.
I had an Ick problem a few weeks ago and I treated with Coppersafe for 3 weeks and seem to disappear.
About a week ago I changed my tank from 10 Gal to 29Gal in preparation for my pregnant platy's fry (popped 3 days ago).
Two days ago I noticed some Ick again on 2 Red Dwarf Platy's and realize I forgot to add Coppersafe in a last couple days.

So I currently have:
3 sunset platy, 1 pregnant (no Ick, they didn't get Ick before either)
2 Red dwarf Platy, 1 of them gave birth 3 days ago (both have Ick)
1 Raphael Catfish
14 Red Dwarf Platy Fry.

My new tank is only 3/4 full; I used the gravel and water from my 10Gal and gradually adding water every day, also using my old filter alongside new one.
Using good test kit my water quality: Ammonia 0, Nitrite 0, Nitrate 10, PH 7.8 and Temp is 78F.
I do partial water changes every 3-4 days and also adding some more water to fill the tank.
I previously treated water with CopperSafe and used Maracyn-Two to prevent secondary infections.

This is my first fry and i would like them to live.

Any help will be greatly appreciated.

Why are you filling your new tank up gradually. Why not just fill in up with fresh declorinated water.
You could be tranferring the whitespot to the new tank. Though whitespot can't survive without a host.
You need to medicate if the fish still have whitespot.
You are only meant to half dose with fry.

Well im quiet new to the hobby (6month) so i was a little careful, i didnt wanna add all new water to my new tank not to face any ammonia problems (i am using my old filter so i guess that wouldn't happen). But currently im cycling my old 10 Gal tank for future home for fry and all the water from old tank is in the new one already along with all my fish and fry. So given the situation i dont have a separate place for fry (they are in breedeing net, till my old tank fully cycles) and now im not sure how do i go about half dosage.

Ok i'm with you now. Get what you mean.
If you do use the old tank for fry now it could have whitespot.

Since i dont have any experiance with Fry, I'm not sure whats the dosage shall be and if Fry reacts to medications differently, so CAN i still use CopperSafe and Maracyn-Two with Fry in the tank or it will kill them ?

No need to use the maracyn.
If you use the coppersafe just use half dose with the fry. Increase aeration.
Sometimes you have to do even less than half dose with fry.

No need to use the maracyn.

Thank you for all your help.

Well its been 3 days since my last post and the Ick cycled again. White spots dissapeared 2 days ago and now it back on. It's been a 12 days using the salt as usual and increased the tamp to 80-81 and I'm still using Coppersafe.
Seems like none is helping because its the Ick's 3rd cycle.

Anything else experts can recommend (Different medications maybe ?)

it can take two rounds of med to get rid of whitespot.
You treat a further week once spots have gone.
