IMo that lighting is not enough even for derasa or squamosa

[ah^siao]

not enough lighting....

at least T5... that's the very least

[DrJekyl_MrHyde]

for 2 footer t5 is 24watts per tube so compare T4 55watts PL to 55watts ....is should be brighter .....than T5 ...T5 are x, and t5 are better because it can punch lighting deeper into the tank but..PL cant ....so how about getting 3 x set of T4 55watts PL = total of 165watts ...should this be enough for clam if i place it high up in my tank on the LR near the light ......?

Mine i am using MH 150 Watts with only a fan blowing. Temp rose abt 1 Deg from 27.2 to 28.2. I have 7 clams in my 2 footer. I notice that they open their mantle bigger after i changed from PL to MH lights.

[DrJekyl_MrHyde]

how many watts PL you were usinf for your 2 footer...Boltthrower ?

[DrJekyl_MrHyde]

it ur tank in a airon room .... but i think that temp will go up and down like 28-30 if the weather is hot .......

or maybe your room temp is low ...... but mine is already 27-28 now .......

[Boltthrower]

I switch on the Mh lights from 8 pm to 6 am in the morning. Temp dun vary that much.

[DrJekyl_MrHyde]

i think at night the temp is lower thats y your tank 28.2 ......in temp, i on my lights during the day .......

IMo still not enough, colourful maxima or crocea need >250watt

[Boltthrower]

That's why I only switch on at nite! Hehe!

It all boils down to the surface area of your tank and the height of your tank.

Let's just say it use up for one to judge. Other people's comment should be taken with a pinch of salt since they have not seen your tank in person.

For instance if the clam is onli 10cm or less from your light source (and your light has reflectors to concentrate the light into your tank only), then placing it directly under a 55W 6,500K - 10,000K PL tube is more than sufficient.

Yeah Fuel, thanks for the info Now i get it...since some people seem to have their own opinion in everything, its hard to judge whether the info is accurate too
