I have a 125 juwel rio with 2 18 watt bulbs. Is this ok for growing plants.If not what should i do?

No is the short answer
You will get some plants to grow in it (low light plants) but for most plants you would need 2WPG; this would work out at about 60 watts for your tank.

What bulbs are in the tank?

Hi Ian,
a good guide is 1 watt per two liters of water for 8 -12 hours a day.

or for depth up to 40cm 20watss for the same time periods.

these are guides only but others will give you more advice later

i have 2 18 watt bulbs. 1 is a daylight bulb n d other is a standard bulb. what could i do to increase the light?

hi,
unfortunately you can't change the wattage unless you change light unit.
you can find high-lite(T5 bulbs) light unit in juwel which would raise the wattage up to
a total of 56W(2x28W unit).
The best you could do,if you can't get a different unit,is add some light reflectors.You could do both.
hope this helps.

I had the same tank, with the same lights for three years and I grew a lovely low light planted aquarium with Java Fern, Java moss, Anubias nana and crypts. Low maintenance and slow growing. I Had to remove it from the room I had it in and sold it. I loved that tank. I now have a Rio 240 in my bedroom with a high light system and pressurised Co2 system. I'm getting lush growth BUT it's way higher maintenance. So what do you want? Low light, low maintenance or high light, High maintenance.

low maintenance sounds good. Thanks
