Thanks.. I'll have a look at that tomorrow. I would be surprised it was water corrosion though as it's been running 2 days and lights failed after 24 hours. So it seems more of a fault?
I've literally got a desk lamp that I can shine onto the side of the tank.
I'm not willing to have the lid off the tank (as i have a child with additional needs who wouldn't be able to keep his hands - and God knows what else - out). Although i suppose i could when he's at school.
I bought a Fluval Flex 34L (9gallon) as an emergency purchase this week because my tank had sprung a slow leak.
I also ordered some new plants - java moss, Hygrophila rosae australis, java fern, plus some marimo balls and Amazon frogbit I already had.
Last night the lights on the tank stopped...
Thanks for your help.
I can probably get meth blue tomorrow but at the moment I would be surprised if he's still alive by morning.
I wish I knew what I did wrong. I feel confident that ammonia and nitrite has been 0 since I got him. I tested daily for the first few days and then every few days...
I did a large water change after the cycle before adding the fish. About 80%
I've done a 75% change today and will happily keep doing the changes. I use Prime already. However there is chloramine in the tap water - measures 0.25 on ammonia tests.
I've done regular tests since adding the betta...
I will try and get a picture later but when the kids aren't around. Trying not to bring their attention to it right now!
I did a god bless cycle using household ammonia.
I don't have a nitrate kit unfortunately
Heater is set to 26C but I don't have a thermometer yet.
