Air Stones for planted tank?

I had a quick question that I was hoping could be answered. Do I need to run an air stone strip in my tank if my tank is a 29 gallon planted tank? It's not heavily planted, only about a half dozen plants but I have noticed that in all the photos I have seen recently of other people's planted tanks there are no airstone bubbles visible. Just wondering if its necessary?

thanks!

An airstone will cause your CO2 to leave the water so it is not recommended for planted tanks. Some people like to run airstones during the night for extra oxygen, though.

wth! hehe ok, thanks! Probably would make sense why I seem to have a shortage in my co2 levels. I'll unplug my airstone strip for awhile and see how it all goes. I learn something new everyday with this hobby.

Another thing that has been nagging me is all the scientific terminology with ppm's and how much NO3 to add and phosphates... how does one calculate what one needs based on the water I have to work with? I'm pretty sure there isn't a onestop do it all test kit is there?

Thanks for the info on the airstone!

as long as your filter provide a little surface irritation you dont need to run an airstone at all. Some run them at night so CO2 doesn't build up

Any surface agitation will also assist co2 in escaping. As long as you have adequate circulation, you don't need to agitate the surface of the water...

There are approximate target levels of each. For example, target NO3 is 5-10ppm. To find out how much you need to add for your specific setup, it's helpful to know how much is in your tap water to begin with. You can either get test kits or contact your water company.

Once you know how much is already there, you can use Chuck's calculator to decide how much of each chemical (N, P, K, and micros) you need to add.

excellent!! Thanks Pia, I have been using Kents blackwater expert and plant supplement, but its always sort of felt like walking in the dark, not really knowing if I'm hitting all the right spots. Those two sites will help greatly.

Fertilizer was one of the most confusing aspects of planted tanks for me.

I'm still trying to figure it out but I think I finally have a regime that's good for me, good for the plants, and bad for algae!

If you need help with it, don't waste any time in posting your problems here. There are lots of really great people that helped me out and can help you out, too!

Weee, here we go again!

Regulars know what I'm about to say... I believe if your tank is covered, you should run an airstone.

Here's the thread where I argued my personal belief:

Check this guy's thread: https://www.plantedtank.net/forums/sh...ad.php?t=18992

DO goes down to as low as 5.5 in an open top tank before the lights go on. I guess this is why Amano runs airstones in his open top tanks at night.

Hogwash!
