no its closed

darren after reading from the other site i have taken them out and dry docked them for the next two hours do they need to be dry docked under the heat light or just out of the water

All I can say is that's a very big and very mature turt for 18 months!

That hood on the tank is not good at all, it creates high humidity which can cause all sorts of problems, you need to take that off and have the tank completely open topped, and fill it up as high as you can without them being able to climb out.

If the water was clean then the higher temps might not be such a problem, but I'm willing to bet it's not clean, and if it's full of bacteria as I suspect then the temperature is encouraging their growth. What filter media do you have in the pond filter?

Probably the best thing you can do for now is to dry dock them, that is take them out of the tank and place them in a plastic tub or a dry tank with a spotlamp so their shells can dry out completely, the temp should be around 32-35°C. Don't put them back in the water until you've seen what the vet has to say tomorrow.

There is some excellent advice here on dealing with shell rot...ATP Medical - Shell Problems

I have been keeping terrapins 32 years! And i do think you need a vet keep ring around everyone till you find one open! If not where do you live ? I have some drops to put in your tank it should help! I hope!

so leave them out all night but turn their light off at bed time so they can sleep i have just been told they are 4 didnt realise i had had them that long sorry my god how time flies you know your stuff so ignoring the other sites and sticking with this site still vets in the morning to see what they say thanks once again for all your help

i live in burnley

tank now half open as the light is fasten to the other half but the open half is approx 1' sq

hope everything goes ok with them, gud luck!

Wow, I'm usually hopeless at guessing ages! I knew here was no way a turt could be that mature at 18 months though.

How warm is the room they will be in overnight?

er not sure they are in the living room the room will be warm untill about 1-30 then the heating goeas off and cools down their light comes on a 8 and heating at 10

You need to keep them warm overnight, if that means leaving the spotlamp on then do it, they'll still be able to sleep as they sleep during the day when they're basking.
Make sure they aren't too warm though, check the temp with a thermometer.
