Hello all,
I'm not much of an aquatic gardener but I do enjoy the use of some live
plants in my tanks.

I've acquired a small collection of plants and placed them in my 240 gal
tank which uses an overflow and sump for circulation. This means that there
is unfortunately a large amount of air/water turbulence.

I understand that this practically strips out the CO2 from the water and am
trying to create a more laminar flow to reduce the air/water mixture. My
last modification helped and now the air/water turbulence is low enough that
I suspect some CO2 is remaining in the water column (albeit not much
though).

I do not currently have many test kits that seem customary for planted tanks
(KH, CO2, etc.) So my question is more of a suspicion type. Could it be
that my tank is also short on other elements such as iron or nitrate that
would make the leaves less green?

The plants are still showing new growth and the new leaves begin a nice
green color, but as they age, they become less green.

Lighting consist of two 250watt MH @6500K each running 10 hours a day.

Thank you,
Fishman



What type of plants are they? Some go naturally reddish at the top as
they grow....Hygrophila being a prime example...I find it quite
attractive...
