My tank is an
approx. 20gallon tank (60cm x 30cm x 40cm).
pH is being
measured by an Ecco pH test pen. KH via AP KH test kit (sample with 20ml of
water to get the max out of the kit.)
Surface
movement is pretty heavy by 2 AC fans blowing directly onto the surface water.
(11 cm dia. AC fan). Filter is Eheim 2026 (hahahahaa...very overkilled
Outlet is using the normal one point outlet though...thinking of changing it
and hooking up to a spraybar instead.)
Reactor? Which
one? I am currently using the internal one like those taiwan UP brand reactor (reactor chamber roughly around 22cm long, 5cm diameter) with
bioballs in it and water fed into the top by the side. CO2 is fed directly from
the top of the reactor via the input point. I have another DIY external reactor
made from PVC similar to that of Ghazanfar Ghori's design. Its 1.5"
dia instead of 2"...will that make a big difference? The reaction chamber
length is 30cm long. I will try to get time to test this reactor again with the
maxi-jet to see if I can get good response time.
So...an
efficient CO2 reactor should be able to get to 30ppm within an hour or so from
ambient levels without the need to crank the CO2 input rate high?
I do see quite
a lot of folks with inefficient reactors as compared to what you have (from the
comments that yours are able to reach 30ppm within an hour or so from ambient
levels.). They either need to crank in the bubble rate a bit to catch up or
start the CO2 earlier via solenoid to hit the good range. Hope I can get around
it quick. Tom, the reactor that you are using for the 350 gallon tank is the $2 reactor design?
