not to be confused with the Ista max mix which has terrible reviews. this one looks to be modelled off the Sera Reactor and came highly recommended by a very experienced scaper Review here
sale link, search "Aquarium ISTA Propeller Co2 External Turbo Reactor" on ebay
As i am running an Eheim Professional 3 - 2073 which has 5/8 hosing (not sure what that is in inches for you americans) and have heard that too much flow through any of these reactors causes the dosilution of co2 to be less effective, finally expelling co2 into the tank through the outflow.
To combat this, i have gotten 2 eheim T-bars which have 5/8 continuing straight with a 90 degree connection for 1/2 inch hosing which i will connect to the ista reactor. Meaning i'll have a little loops running off the main 5/8 hosing.
Questions for anyone who can help:
1 - will the offshoot of flow be TOO low?
2 - will this affect my filter or overall flow too much?
3 - anyone done similar - and have advice?
