AquaVitamins Posted May 21, 2009 Report Share Posted May 21, 2009 I have a heavily planted tank, and i was wondering if i could get away with out adding O2. Plants produce it, so does having a heavily planted tank mean i dont need to add it? ? Edit: Sorry i meant to say, With out adding O2 for the fish. I wanted to know if i would still need an air pump if the tank was planted. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted May 21, 2009 Report Share Posted May 21, 2009 you mean CO2? can we see a pic of the tank too pleasE? Quote Link to comment Share on other sites More sharing options...
HaNs Posted May 21, 2009 Report Share Posted May 21, 2009 I lol'd Add flourish excel + pmdd and you will be pulling out plants! Quote Link to comment Share on other sites More sharing options...
VinsonMassif Posted May 21, 2009 Report Share Posted May 21, 2009 If you did mean oxygen: If you have adequate surface agitation there should be plenty of O2 exchange and you don't need to add it. A spray bar is ideal for this. On a side note - having an air stone in a large tank provides little oxygen anyway. The bubbles need to be very small, and slow rising for there to be enough time for the oxygen in the bubbles to dissolve into the water column.

HaNs Posted May 21, 2009 Report Share Posted May 21, 2009 And surface agitation = bad when using co2 injection Quote Link to comment Share on other sites More sharing options...
Navarre Posted May 21, 2009 Report Share Posted May 21, 2009 You dont need a pump. you dont need an airstone Plants use co2 during photosynesis and release o2 in return I have a 3 ft tank that is heavily planted feed sparingly and has a trillon guppies in it the heater provides thermal layering which SLOWLY moves the surface water as does the natural warming of the room during night and day Tank has been running for an age no algae No PMDD no Flourish no CO2 has a sword and 3 types of Crypt no water changes (3 a year if i am lucky) and I dont need to clean glass. I wouldnt put cat fish etc in there but it is a matter of balance and what you want to keep. Some people suggest like a SW tank where Coral does not equal Fish that Plants do not equal fish but it is purely a balance issue HTH Navarre Quote Link to comment Share on other sites More sharing options...

Navarre Posted May 21, 2009 Report Share Posted May 21, 2009 You are right to an extent Hans but I have a forrest of plant and fish with no filter as I said I guess it is about what you want. I "prune" out my crypts ...i get a good handfull once a month or so so no probs with growth but it comes back to what you want your tank to be and balance. I have a low maintainance tank that looks spectaular ( IMO) and has nice fish. Little in ...a lot out. It keeps me happy lmoa If you want a fast to ripe with high maintainance tank then go for it...and in saying that I have a 400l discus tank that is heavily planted that I do add all the gunk to and inject and prune and water change etc etc so I guess its about what you want for that tank HTH Navarre Quote Link to comment Share on other sites More sharing options...

nemines Posted May 22, 2009 Report Share Posted May 22, 2009 yeah as said above, for oxygen, plants are the best as they release it in its dissolved form with bubbles only noticeable once maximum oxygen saturation has taken place. In regard to Navarre's tank, it can be done but for optimum plant growth (unless growing pond-type plants) water movement is essential around the leaves to help them exchange nutrients and waste with the water column. If you are using CO2 then surface agitation should be minimalised and a surface skimmer can be installed to help keep the surface free of dust etc. All about finding what works best for you though!
