Hi all,

been playing on and off over the years with a 46g bowfront tank and not really had any success in getting good plant growth so decided to give it another go before swapping over to a traditional chiclid tank:icon_mad:

so i have set up a small disc diffuser at the bottom of the tank but the majority of bubbles get to the surface before they have disolved or reduced significantly in size so i have positioned the diffuser below the filter intake ( eheim 2026), now I am often getting and hearing bubbles in the system but i dont think this is norm as shouldnt the CO2 disolve when in the filter???? - i am running about 3-4 bubbles per second ( but that is relative to the size of the counter of course)

i don get any bubbles out of the spray bar but i hear a large amount of air/gas every 30 - 40 mins in the filter.

I did have a reactor but it was crap hence the swap to a diffuser.

thanks in advance for any replies!

My Eheim did the same thing,and my CO2 level dropped so I went back to my Hagen
elite to diffuse the CO2 it does a good job but I may try an inline reactor just to get equipment out of my small.

I always diffuse my co2 directly into my my canister. Some times it "burps" but that is just what happens.

I assume it just has to do w/ some of the gas getting trapped between the sponges, floss, rings, etc. A few burps here and there might waste some of the gas, but all in all it's relatively efficient and effective IME.

I've been injecting CO2 into my Classic Eheims for years and it works like a charm.

Do your Classics burp co2? I've tried it with my Rena and it burped to much.

Oh sure but not very often and never very loudly. I get a good spraying of bubbles from time to time but nothing I would call a burp.

I only use ceramic noodles and Bio Balls as media... nothing else. A 2217 filled with about 2/3 noodles and 1/3 BB makes for a very good reactor.

A big plus on the Classics is that the input goes through the bottom of the canister and out of the top this results in less CO2 pooling (due to bypass)at the top of the filter. I have found that I can get by with 2BBS on my 90Gal. So it is pretty efficient. And that is with a NANO diffusor BTW.

I use a 2213 and a xp1 with pads and bio media, both burp from time to time.

Here is a link to how I setup my diffusor:
