Low alk since switching to Gen-X reactor media

[Delphinus]

Wow, that sucks .. What pH are people running these things at? I remember the Schuran reactors when they first came out, people were running them at insanely low pH values, like in the 6's or possibly even the 5's. Which means significantly higher CO2 rates obviously but maybe the catch is you can get away with a slower effluent rate. (ie. in the end the same amount. or close to the same amount, of CO2 "escapes" into the tank, so to speak).

Good luck figuring it out! I'd like to know too since I was going to switch to this media once I've finished up my current A.R.M. (old style smaller particles, dang I seem to have a ridiculously large stockpile of it .. apparently I didn't need to "oh I'll just order one more container of A.R.M. to finish up the shipment" quite so much.. )
