    Apparently heaters should b placed on the output line as well. I'd thInk this is because u lose less heat as the heated water goes strait back into the tank?

    Hi Ivan,

    I agree with Shihr.
    I have almost the same thing with my tank, and to tell you the truth, i thought that it will not be good for your filter bacteria, if say, your new heated water from your inline heater goes thru your cannister first, before it goes into the tank, as this water might be to warm for the bacteria? This is not a fact, but something i thought about setting mine up.....I might be wrong here :)

    Re: DIY Inline heater and CO2 diffuser planning

    Hi Ivan. I'm also planing to do something similar like this. Why do you drill a hole in the DIY heater holder and place your CO2 line in there. That will mean that you have less equipment that means less water restriction. I guess you are going to use a eheim 300w heater? If so did you found a grommet yet that will seal the heater and where?

    You mean this one lol.[​IMG]maybe I must get the information on these cable flange`s and post it for everyone to see. I plan to build another one for my other tank so I will post that one and some information on the flange.

    Re: DIY Inline heater and CO2 diffuser planning

    Thats exactly how i planned on fitting the heater. thanks pierre for the post.
    in regards to the heater before the filter: makes sense to the bacteria, so i will see if i can make the heater and diffuser together as one.

    now the searching begins...oh and i will be using the eheim jager 200w heater.

    Wouldn't one get better diffusion if you swop the Heater and diffuser around? Or could this create unwanted bubbles in the filter?

    Isn't the heater set at the temp that you want to heat the water to, which is the temp at which the bacteria are surviving currently?

    Re: DIY Inline heater and CO2 diffuser planning

    Unless you have a pre-filter on your inlet, you'll have a heck of a lot of gunk collecting in there if placed in-line on the inlet pipe. That's why you'd generally want all in-line equipment on your outlet after filtration.

    Also putting CO2 into the canister is probably less than ideal for the canister bacteria.

    So on the return, first the CO2 then the heater or first the heater then the CO2 ..

    Re: DIY Inline heater and CO2 diffuser planning

    I would say put the heater first and then the CO2. Reason for this being that you could get bubbles to build up in your heater chamber (also known as cavities). These cavities could lead to problems and also possible damage to your heater

    +1.

    I have something very similiar to what you described there Double-D, and sometimes when swithing the filter off to do maintenance, it sometimes seems there gets air traped inside the heater compartment.
    I havn't had any problems with these air locks before, but i gree on what you said.

    I have posted this pic of my setup before, not the best, as the heater department can be done better, but don't know if you have seen this @Ivan ?

    Re: DIY Inline heater and CO2 diffuser planning

    I think that should do the trick dude! I do however wonder how much water flow will be lost with all those 90 degree bends in the tubing?

    Re: DIY Inline heater and CO2 diffuser planning

    i will try and minimize the amount of 90deg bends. the only one being kept is the one of the heater. but the rest will be connected via pipes and so minimizing the amount of bends.

    i think you might lose a lot of flow with all those right hand elbows..

    see if you can keep it as straight through as you can..
