Day 4 - Slime!

I pruned some of the more yellow and shabby looking leaves (mostly Vallis) and replanted the plants that had floated free of the substrate.

These were the Vallis leaves:



Slime!
Today I noticed a slime had built up around the CO2 diffuser. I pulled it off, it was the consistency of snot but smelled sweet. I suspect it's the yeast/sugar solution from the bottles which has traveled down the airline.



I've done two things to try and rectify this problem:

1. Made sure the airline coming out of the drinks bottles doesn't drop down below the top of the bottle. Previously the airline came out of the bottle then dropped down to the floor before going to the tank above. Now the line goes directly up to the tank.
2. I've lowered the diffuser so that it isn't so close to the intake of the filter. I figure the gentle suction of the filter intake must also be gently sucking on the airline.

We shall see if this solves the problem. If not I shall install a third bottle designed to catch the gunk that comes from the yeast filled bottles, like this one.

Below you can just about see the white diffuser sticking up through the gravel.
