Eden 501 spraybar with CO2 injection?

[ptjw]

Hello, i just got myself an Eden 501 canister filter...i was previously using an Emperor powerhead.

I have my own DIY Co2 all set up and working well and i used to plug the airline into the outlet of the powerhead and the Co2 gets diffused very well into the tank.

problem now is i can't do the same with the Eden filter, is there a way to attach the Co2 outlet anywhere such that it goes into the water with the rainbar? i've seen a video of someone on youtube (can't remember which video anymore) with an airline connected to his rainbar and it works...

does anyone have any experience connecting Co2 to a rainbar? i think can make one of the holes on the bar bigger and stick a small pipe into it but i don't know if this would produce a venturi effect such that it sucks my Co2 into the rainbar (my DIY Co2 doesn't have very good pressure )

thanks!

ok i took a gamble this morning and i answered my own question...i'm posting it here so that if anyone had the same question as me would know:

i took the rainbar and used a pair of pliers to increase the size of the first hole nearest to the input (where the water first flows into the rainbar) and i made it just big enough for me to force an airline connector into the hole. I tested the new connection for leaks and it was a tight seal (no sealant/adhesives required). I put the rainbar back into the tank, and i connected my DIY Co2 airline to the connector and turned on the filter and it works!

my DIY Co2 setup produces about roughly 1bps and the bubble gets washed around in the rainbar before getting expelled out of the holes along the rainbar in a fine mist...so there, modified Eden 501 filter with Co2 input

I don't think the bubbles are getting mixed in the rain bar, more likely, they are being expelled (more or less) evenly into your tank. Nevertheless, well done on the simple diy solution.

Cheers
