    I rather prefer to have a higher pH from tap, then maybe I won't need to have coral chips in IOS to prevent it falling.. heard shrimps prefer soft water but no choice if I take out the coral chips pH can drop to very low (to about 6)

    Me too prefer higher ph where i still can inject a little Co2 for my moss & pelli..

    Now i not even dare to try using ADA soil tank base.

    Just some thought i have gathered so far .
    Sorry for the nagging . I maybe wrong. Feel free to edit.

    From what i see high ph can be a problem when u do water changes and etc.

    Here are some problems i faced:

    1. Imagine adding tap water of 7.5 to 8.0 into a tank of 6.7 to 6.8 Ph, water change too much or too fast is dangerous which might induce PH shock. Tried Ph down it dont work well with (Active Carbon and Coral Chips).

    2. And too much Co2 = instant dead shrimps. I guess also it reduce the maximum limit in the numbers of shrimps u can keep in a tank. Co2 is my last resort to bring the Ph from 7.1-7.3 down to 6.7 -6.8 as the red ADA is not helping much in my case. Ph fluncatuates a little when the Co2 is off during lights off period again it rises to around 7.0-7.2. (Timer with Solenoid controlled Co2 input)

    3. I still need to add coral chips to stabilize the PH/KH anyway also Ca and Mg supplement to the water.

    4. Plants not doing well because of lack of some fertilizers also possible there is not enough CO2 although i followed the KH/PH chart closely which is around 20 -24ppm.

    Or

    My dream situation:

    Low Ph with low requirement plants like moss and pellia.

    1. Good coral chips introduced during the ageing of water if Low PH.
    2. Less dead plants = less ammonia/no2/no3.
    3. Lights on and off has minmium effects.

    4. Can consider undergravel filter(Non-ADA) with river rocks good if you want regular maintaince.

    5. Can introduce Sponge filter with air pump to increase oxygen(i guess helps slightly increase the maxmium limit of the numbers of shrimps you can keep in the tank) and dont have to worry too much Co2 will escape resulting sudden increase in PH.

    The water from my tap always ranges from 7.3-7.5 for PH.

    Simcb,

    Good input from you. Need to think about all these for my new tank setup. Just order my 2x1.5x1.5 tank with IOS from the tank maker today.

    Still havent decide what's the best possible setup for shrimp.

    Spinex,

    Some input for you to consider for your setup....

    In the beginning days of my keeping shrimps, I alway read that moss is a must in shrimp tank, some say that shrimplets needs to feed on microscopic organism that moss produces, some say that it alter water chemsity suitable for shrimps.

    I decided to check if it is fact or myth. For my newly redo tank, I don't use moss at all, just use fast growing plants. The shrimps hide less than tanks with lot of moss, shrimplets are developing and growing well like tank with moss.
