How do you mean they are the similar avtars? mine is obvoiusly an x-ray of an unexploded hand grenade imbedded in someone's frontal lobe and teevees is an MRI of a head!
You are right about the sitting water going stagnant, I only have 5 powerhead and 7 places I needed them and only 3 thermoters to go between them. I am in the process of trying your suggestins Beverly in between working this week, there is not a big rush anymore as every coral is now dead and three of my remaining fish were dead when I came home half an hour ago. 1 sailfin and 2 chromis, the lawn mower bleeny does not look good and will be going down the toilet soon i suspect.
I then I will have no fish.
This has not been a good week. rachel
