i'm running 2 Penn-Plax Cascade filters. The one the CO2 is going into is a 700. It works the same way (water traveling from bottom to top.)
lol....i can just imagine it now....every few days there will be a post in this thread of people proclaiming that they purchased their first pressurized co2 setup.
good luck folks! i was there once too...
OK....dumb question but I am very new. Like yesterday starting new. Can you not use the little tablets that fizz like alka seltzer for Co2? That is what they were advertising them for. HELP so much to learn.
it is a lot of info. you will get there!Thank you cob freak, so much to take in, on my way to fish store to have water checked!
