water temp

[kenneth_kpe]

i would like to know what the effects of warm water would be to aquatic plants, im having a hard time bringing the temp of my tank down to a good 25 deg. Cels. its currently playing around 30-33 depending on the time of the day. at night it drops to around 29-30, its kinda warm here

plants like java moss and riccia for example or plants in particular ?

 

[Lateral Line]

Java Moss and Riccia generally are quoted as having a maximum temperature of 28C. Obviously, some of it will survive at higher temperatures, but it is far from ideal.

Wow, that's close to 90* F

I would worry about fish first, then algae, then plants. I say algae because I remember reading that algae likes higher temperatures or something like that

Plants because I also specifically remember reading that some don't grow the same in higher temperatures or at all.

 

[Silly me]

I know that java fern does well in my discus tank, but most plant growth slows down.

I know that higher temp means less Oxygen content in water, dunno what it does to your CO2 tho.

could this be the reason why the color of my java moss is at a constant brown ?!!? hmmm some of my plants doesn't seem to mind the temp, they are growing quite nicely but not wildly.

Btw what is the effect of the said temp to riccia if ever since it has a 28 max out temp, would it also turn brown ? : )?

must lower temp !!! anybody got advice on how to lower my tank temp ? ( without the purchase of a water cooler ) haha would fans make a big difference since i note the temp of my water at around midnight after 5 hours of no light to be at around 30 Deg Celcius ?

I used to have the same problem, and in the summer my Rotala rotundifolia used to get brown leafs. But once I found out that it was because of the heat, I simply opened my windows and floated some ice cubes in the tank. De-chlorinated of course. Or simply keep a few in a bag and float it in your tank. Always worked for me.

However the temp in my tank was always a few degrees lower come night. It used to be really high durning the daytime, often up to 82-83F but since I switched to compact flourescents, it defn. didn't heat up the water as much as my previous incandescent lights. Maybe you can keep yor tank in the basement or something? Mine already is, and still the temp was so high.

I know you can get a small fan or something but that'll surely affect the surface agitation, and if you want your CO2 to diffuse, well, I'm sure you already know where I'm going here.

 

[kenneth_kpe]

eeek i dindnt think about the agitation with the fan, im gonna try rewiring my hood, im gonna move the ballast away from the inside, maybe it will significantly lower the temp inside the hood during day time hehehe

 

[Discomafia]

Yea, but the thing is I usually float ice so that the temp during the day time when the lights are on lowers to a reasonable level, say 76-78F. Then at night, I wouldn't have to worry as my room temp decreased, therefore so does my water in the tank. But you wrote that the temp in your tank even at night after the tank lights have been off for some time, is still quite high. Is there any way you could cool your room down, maybe that'll help some. Don't think you wanna wake up every few hours to add ice into yout tank, do you.

 

[kenneth_kpe]

well i dont wanna run the air conditioner the whole day, thats gonna bring the electricity bill pretty high hahaha im gonna try some things out and see what helps, maybe add an intercooler from a car to the tank haahhaa jk jk

 

[barbus]

Oh man.. I told you to get a fan, now you wanna put intercooler Fan will make surface agitation but not so much a loss of CO2 though, not in my case with pressurized CO2. Would you believe that the best temperature I got with fan is 24C, and average daily is around 25-27 ?, here is the proof and the fan

BTW, is it really that hot there ? could it be also affected by your lighting / enclosure with poor ventilation ? I don't think any moss can survive that temperature, if they are brown, most likely they're dead .

An aquarium chiller like this will work better then an intercooler. Intercoolers use the forward motion of a vehicle to force air through a specially designed radiator to affect their chilling action. Unless your tank is moving at reasonable speed, an intercooler will have no effect.

 

[kenneth_kpe]

eeeeeek !!! the price !!!!!! hahaha
im just kiddin about the intercooler part, but what if i circulate the water more with the help of a water pump and place it inside a bucket to allow it to cool down before going into my tank.. hmm but thats too hard, im gonna try the fan,

anyway i wanna try not using my light for a day and see what the temp of the water would be, or is that just stupid ? the temp should be the same at night ? just wanna try things out, and yes its pretty warm here, ( philippines ) hasn't rained for a month now and thats bad !!!!

or i could rewire the ballast to be placed outside of my hood so that the temp inside the hood is minimized, just the lamps are left, ?!?! im wondering

btw barbus where are you from ?

 

[Silly me]

I use to have a big wet and dry filter on my tank that drop the temp of my water. worked like a big radiator.

>>> i could rewire the ballast to be placed outside of my hood

That is a good idea even if you didn't have heat problems. Ballast are very sensitive to damp/wet conditions. I have never mounted a ballast inside a hood.
