DIY Ca reactor

[reef_guru]

this thing is going to be a beast, 3 chambers, all recirculating, ran out of cement so heres some pics for now. the beer bottle is for size comparison. dimensions 6x6x20 each, the tube is going to be the CO2 bubble counter.

Yeah!!! I love square stuff.

Here's a square CA reactor I built

[reef_guru]

flat acrylic is cheaper, the footprint of flat acrylic offers more sq/ft than tube stock. yours differs from mine in that the one im building will have a pH probe on the intake side of the pump, along with a recirc pump for each additional chamber, and a bubble counter.

Friggin' cool!

I'm not understanding the whole bubble counter and CO2 stuff, would you explain in "Linda Language" for me?

[reef_guru]

the main pump is a 2-mdqx-sc and the recirculating pumps are maxijet 400's

you match the CO2 bubble rate ( amount of bubbles ) with the effluent flow rate ( amount of flow ) to get a 6.5-6.7 pH based off of your tanks dKH consumption rate.

Ca reactors only work when the internal pH is low. the media wont dissolve above 7 pH. CO2 lowers pH

ahhhh ok I think I gotcha! I'll ponder that a while longer! Thanks! pondered...is there a chart or something to follow by?

[reef_guru]

heres a site to get you started. figure out your tanks dKH consumption rate then plug the numbers

Reactor Setup help

cool thanks!
