Re: My simple 10g I already have one, and the HOB is temporary while I wait for my replacement double-tap to get delivered. (You are quite the intuitive one!)
But FWIW, the HOB isn't really doing much harm to my CO2 levels. I have the flow set at the lowest rate, so there really isn't all that much surface turbulence, as long as I top off the water every morning. The drop checker stays lime green all the time.
The real problem I'm having with the HOB is simply that I can't direct the flow where I want it to go. But yeah, the double tap should be here by early next week, so the Eheim will get hooked back up.
I love Eheims, but I have to admit, those double taps do tend to leak for me, all throughout the years I've used them. I think I'm officially going to be a Filstar man from now on, for all the new tanks I set up. |
