Nutrafin CO2 Injector #1
Quick question ...

I've got a 77 gallon tank and use 2 Nutrafin CO2 Injectors suitable for only 20 gallons each.

I use daily and weekly fertiliser, root tabs and aquagrit.

I'm working on the principle that some is better than none, am I right or just wasting my time?

It's a lightly stocked tank - 6 harlequin rasbora & 6 threadfin rainbows, MTS's and 7 Cherry Shrimp.

Re: Nutrafin CO2 Injector #2
and another ...

They're on 24-7 ... I've pm'd an fk member about a clip they mentioned in a post and await a reply. Does anyone have any recommendations?

I had ideas along the lines of;
- take the hose out of the water during lights out??
- peg the hose to stop the flow??

The Hagen/Nutrafin website doesn't mention stopping it as an option grrr so I'm worried any action I take could have detrimental affects ... advice appreciated.

Re: Nutrafin CO2 Injector #3
They're safe to leave on 24 hours, there should be some benefit but I don't know if you'd notice.
You could run an airstone overnight to ensure that the CO2 doesn't build up - airstones are a good idea anyway as they help with circulation and oxygenation of the water.
