Another Co2 Question!

[Haveagojoe]

Can the yeast method create some sort of residue inside the tank, i've noticed what look tiny grains of stuff on the rocks they are a greyish colour and the only thing I can put it down to is yeast,I took the diffuser out and the tubing and noticed the output end of the tube had what looked like a build up of the same stuff and the outside of the tubing had a coating of it as well, there is no yeast bubbling up the tube from the bottle and no tank water has got into the bottle as I have a non return valve fitted, is this normal or do you think I should fit some sort of scrubber into the top of the bottle,any ideas,thanks.

You have a picture of the residue?

I'm really not very good at putting up pictures am I but lets see how these go, as I said they look like tiny grains of grey salt, I hoovered up a lot last night but more have returned today.

Any ideas anyone

Honestly, I have no idea, though I can understand why you think yeast.

I'm starting to think along the algae line now

Awwww, I'm sorry. How do you have your CO2 setup? Maybe we can nip this in the bud... LOLOL nip in the bud... I"m funny.

Its a diy set up and I use the nutrafin ladder diffuser,it knocks out about 1 bps and its a 100ltr tank (or so i was told when I got it second hand)I also dose wth liquid ferts once a week and the tank is quite well planted and they all seem to be thriving,espiacally the jave moss which I have to trim back,btw I've just intoduced a pair of zebra loach (botias) and they have cleared the rock in the picture completley that what makes me think its algae.

Do you use a dropchecker to measure you CO2?
