It will be interesting to see if the entire ceramic surface produces bubbles.
What bubble rate will you be running Chris?
Yea, that will be interesting and something i have been wondering myself. I have thought a lot about it and concluded that the quality of the ceramic disk will be crucial. Surely if there is any area of significant weakness or alike, the bubbles will stream from that one point. Of course, if it is uniform i should get a nice even bubbling from the whole surface. BUT lol, will it even make a difference either way?
With regards to bubble rate, its definitely something I want to experiment with. I am at present running my tank as practice for the remodel in a month or so! I am learning all the time and understanding what works and what does not! If I am being 100% honest, i am running my CO2 system through the nutrafin ladder (whilst waiting for the ADA diffuser) at just over a bubble a second and i couldn’t ask for better growth. My riccia is in a sand substrate, zig posted a while ago about him knowing people have had limited success with sand and glosso and I can tell you now that it is growing like wild fire! Jimboo only send me some fresh stuff (additional to what i already had) about 10 days ago and I’m nearly half way to lush thick carpet. Each single plantlet had now about 5 runners.
With the ADA diffuser, the thing i will be looking for is QUALITY of growth rather than NEW growth. Will the distribution of CO2 by a supposedly quality diffuser, produce better quality of growth than that i am already getting? Surely if the CO2 mist is distributed more evenly around the tank one would hypothesize that I should...we will see.
Back to the question, probably start with 1 bubble a second, see how it goes and test the water CO2 concentration for a rough guide just to check it’s not too high. Then from there I will try and increase it to a max without stressing the fish and see how that works. I have seen quite a few ADA setups of tanks similar size running 2 bubbles per second so I’ll experiment. I dose ferts plenty due to high tap phosphate levels and as zig recommended I try and keep nitrate levels proportionate, therefore I presume my CO2 should be high to keep the ratio and make sure it is not the limiting factor.
I was going to fix it up tonight. Decided I have too much work to do and want to do it properly so I will resist and do it at weekend. If anyone has any comments about anything I have said, please post…I am interested to hear other people’s opinions, views and ideas.
Chris
actualy no you shouldnt good on ya 
eek!
