So is it better to have an airstone or surface rippling?

So do we have an answer to this question?

Ok I found out what it is. Now I am confused... What increases O2 and CO2 levels in a tank? The surface breaking? Doesn't vigorous surface agitation remove CO2 from water? Also, will O2 not increase with an airpump? I mean a venturi blows O2 into the water which presumably will increase O2...

Thanks! What is a venturi?

So it is established that gas exchange does good. What would be the best for a low tech no co2 and no liquid carbon tank....aeration, surface agitation or surface skimmer? Thanks

Hi Jordi this is a no co2 tank correct? No pressurizes or liquid carbon? Which plants did you find to grow well under these conditions? Thanks

Do you have co2? What plants do you have?

I have decided to use ADA Amazonia as part of the tank substrate. I know I should perform daily water changes for 2 weeks. Does this also apply if I am not adding CO2 (low tech)? thanks

OK so the plan is to build a 90x40x40 cm tank. I am thinking of getting this 60cm light fixture from my local pet shop: http://www.amazon.com/Glo-Output-Lighting-System-24-Inch/dp/B000VK1A94 Question: Will one 60cm T5HO be enough above a 90cm low tech aquarium? Thanks

Hello if creating a low tech with crypts, anubias, ferns and some easy stem plants, what substrate should I use? Plain gravel or JBL Aquabasis topped with plain gravel? What I am trying to understand is that if certain plants that have roots into the substrate would benefit from the aquabasis...

For a low tech 160L tank, will a 1200 L/h filter be ok or do I need to go one step further to 2000 L/h?

Do you have a journal for a low tech tank I can follow? Sent from my GT-I9505 using Tapatalk

Do I need to do water changes or just a water top up? Because I think that a low tech tank with 50% weekly water changes causes BBA rather than if I just topped up with water the evaporated one. What do you think?

Hi, so a friend of mine decided he would like a planted aquarium. He said he would take care of it and that he want's an amazing looking tank. I have decided to go low tech for 2 reasons...1 if I knew how to make an amazing looking tank I would have done it myself :) and 2 I have no faith in...
