Hi all. We’ve had a new 70l tropical tank for two weeks now. Six small harlequins in it. Fake plants.
Water testing today showed high levels of carbon dioxide and hardness of water a bit over the limit.
I’ve ordered an air pump which will arrive tomorrow and will add easy balance to tackle the hardness.
There is something really odd happening though. I’ve attached photos. There is something brown building up different places in the tank. Never seen anything like it before. I’m worried it’s a bad sign. Can anyone help? Thanks.
