  1. What I don’t get is why the rainwater in the water tank has a higher PH than the bore water. I would have thought with a lower hardness I would get lower PH? :-?

    Is it something to do with lower hardness causing leaching from the concrete water tank?

    Why does the PH of the water from the tap drop from 8.8 to 7.8 overnight?

    What can I do to prevent this happening again? Coz it freaked me out! Thought my fishes were gonnas.

    Put grit in all the filters? Stick to smaller w/cs ? What would happen if I put grit directly into the water tank?

    Or am I thinking about it too much and should forget the whole thing? I’ve given myself a headache now :D

    I'd say the concrete water tank is the reason for the higher pH of your rain water, concrete will continue to increase the pH and hardness of your water for a long time. The pH from the water from your water tank probably changes depending on how recently its rained, drops after decent rain and slowly goes up when its dry.

    Your bore water probably has a lower pH because of the rocks etc it travels through in your area.

    Putting shell grit in the filters or water tank probably won't help because your pH is already going to high. Might be easier to use bore water for your fish tanks if you can, or collect rainwater into a separate container for your fish with maybe a bit of shell grit added to that.

  2. I'd use H3.1 treated timber (usually used for outdoor stuff like decks) to be on the safe side. I wouldn't use kiln dried LOSP treated (H1.2 or H3.2) timber for in a damp humid environment like a fish room.

    H3.1 is LOSP treated, its the H3.2 that's usually used for outdoor stuff like decks

  3. Why not just get a generator, you can get them quite cheap and it will run as long as your supply of petrol lasts. Also you could power more than just your fish tank if you have a power cut.

  4. Looks like you can't change the probe, for that price i would not expect it either.

    Just be aware you may only get about a year out of it.

    If you are really wanting good results you would need to calibrate it every time you use it. A lage part of the cost will be the buffers.

    We just brought a probe worth about $900.00 these get replaced every 6 - 9 months and they calibrated daily.

    What are you doing with your probe for it to need replacing that often?

  5. What you're already using should work, are you trying to raise it faster?

    You could use baking soda to get the pH of your tap water quickly to round what you want before adding it to your tank and keep using the shells, limestone or coral sand to buffer the water in your tank to stop it drifting.

  6. I've done the coconut cave in the past too.

    I found you could crack the coconut straight down the middle if you hit it on the concrete after you've removed the liquid. You sometimes have to bounce (yes some of them will bounce) the coconut quite hard before it will break and it doesn't always work, but its quick if you don't want to saw.

  7. Put the pump under the house or somewhere out of the way where you won't hear it and use a long airline to the tank, just need to drill a hole in the floor or wall for the airline to go through.

    Or else you can try ear plugs :)

  8. Why not partially mix the RO/DI water with tap water when using it for your tanks to put some of minerals back. And if you want to add anything for your plants, pH, buffering etc, do it to the mixture.

    Seems silly to take all the minerals out then add them again to pure RO/DI water.
