    After tuning the right effluent output of your CR so that your KH is at your desirable level, you need to check your KH level regularly.
    When your KH level drop you need to increase your CR effluent output to increase your KH level back to your desirable level.

    I did that after I start using CR and have no issue to increase the CR effluent output until 2 weeks ago.

    If increase the cr effluent, does that also means that the PH in the CR will also rise? Thus lesser concentration of the effluent.
    Maybe say 6.5PH before increasing effluent.
    After increasing, become 6.6/6.7??

    2 weeks ago after checking and found my KH level drop I as usual try to increase the CR effluent output but even after fully open the control valve the CR effluent output never increase.
    Because of this the KH level start to drop over the last 2 weeks and this morning was only 6.0

    I start to check if any valve is clog that cause the flow to decrease.
    The 1st valve is the one way valve from the T joint at the Rowa FR output
    I remove the tubing at the one way valve output.
    The flow is very slow .Same as my CR effluent output flow.

    Look like I find the problem.
    The one way valve may be the cause.
    Hence I proceed to remove the one way valve from the FR output tubing.

    After I remove the one way valve I find the flow from the tubing is equally slow.
    Hence remove the tubing and change a way one.
    The flow immediately increase at least 2 to 3 times.

    So the culprit is the water tubing from the T connect at the Rowa FR output.
    After changing the tubing I connect the one way valve back to the new tubing and another tubing to the CR
    input.
    Now the CR effluent output increase in flow.
    I readjust the CR effluent output back the the normal continuous flow .
    Tomorrow I need to measure the KH again to ensure it is not increase too much due
    to the increase in CR effluent output flow.

    Hope this incident I share help those who is using CR to check their water tubing regularly if they find they cannot control their CR effluent output flow any more with their control valve

    Something build up along the tubing? Thanks for sharing.

    Ya. The tubing start to have some grow.Result in the flow become so drastically smaller

    When you want to supply more kh/ca by increasing effluent, you should also increase the co2 bubble count. So to maintain at the same ph. Because more effluent = faster the co2 exits the reactor chamber. Unless, you are using ph control and oversupplying the co2. Then it shouldn't be a problem when u increase the effluent withoht increasing the co2 bubble count.

    Sherman, did your PH still maintain when u increases the effluent??


    Effluent tube do get clogged slowly overtime if your effluent is veryy slow and especially u are using the ball valve to restrict the effluent. Do take note on that, like sherman just pointed out.
    Hahahah

    Hi JH. I do effluent adjustment when kh changes. I also monitor the effluent ph after each adjustment.(Not immediately)
    If the effluent ph drop I will increase the bubble count and bring it back

    An old thread I find.
    Problems one face when using CR.
    I still face such problems every now and then.
    Anyone has better solution for such problem like outlet clog,
    low kh effluent, bubble trap ,etc
    Please share your good and bad experience and how to minimise or elimante
    those problems.

    Thank You

    It's simple.....Don't bend the effluent tubing. Let the air(co2) vent off else it will accumulate n cause an airlock situation and stop or reduce the drip rate.

    Thank You James for the fast response.Air venting is something that I always forget.
    Only remember when KH starting dropping then search around and found air lock.
    Wonder have self ventingdevixes when air lock up.

    The easier approach is to run higher quantity media and allow high effluent drip rate then adjust your pH controller to match kH consumption.
