Extremely soft tap water

Hi, I've started a 10gallon planted tank a few months ago. I don't use co2 injection. But my tap water is extremely soft. It's glacier run off water we have here in vancouver. My PH lowers at night and raises during the day. There just no buffering to prevent the PH from fluctuating. I put a piece of dead coral in to try to prevent it from falling below 6ph since I heard the biological filter doesn't work below 6. Is there anything else I can besides adding a piece of coral to the tank? I want the ph to be stable. The tank has to be stable enough for me to go on vacation for 2 weeks with an automatic feeder. I have 6 neon tetras, 1 male crowntail betta 5 Amano shrimp and I think I have 2 dwarf cherry shrimp left assuming my betta hasn't found them yet. I think the dissolved mineral content in my tap water is 0.3 ppm

You could try some baking soda for adding some kh which would help with stability, seachem equilibrium or other similar ro water reminerlizer would help with Gh.

P.S. It's much easier to raise ph then lower it so count your self lucky! I wish I had your water.

I'm pretty sure you could breed your neons with that ph.

I haven't tried to breed them. But it's only 10 gallon. And I'm sure the betta would eat the fry anyways. Neons are dirt cheap here if I wanted any more. But something weird happened. My cherry shrimp turned black with a white stripe down its back

Im in Vancouver too!.
Yes, after the billion dollar upgrade to our reservoir, delivery and filtration systems, we have the purest source water in the world. It's as close to rodi as you get anywhere. You can find info on it here:http://www.metrovancouver.org/servic...s/default.aspx

My tds/kh/gh levels are always close to nil when I test and tap ph was 6.3 the last time. You can definitely use sodium bicarbonate to boost the kh. I personally use seachem's equilibrium and alkaline buffer to get my levels up. Mostly because of the deal I get on the larger quantity tubs but, they do have great products.

Yes, we're very fortunate here in Vancouver as far as soft water is concerned, for creating ideal conditions for many species of fish, particularly south American varieties which originate from soft water content, low in TDS's - it's actually great for keeping discus, for example. My tap water is usually around 6.8 and settles in to the tanks at around 6.5 or less - quite stable. I love it !
A little Equilibrium dosing doesn't hurt at all - very easy to maintain good water conditions.

You guys should be the discus breeders of the world. I have dream my whole life to have water like that.

I would be watching my kh to low of kh won't be good for very long. There all kind of product's that raise kh and ph. Check out seachem products.

How much of this equilibrium stuff do I use? And do I use it with every water change?

To raise mineral content/general hardness (GH) by 1 meq/L (3 dH), add 16g (1 tablespoon) for every 80L (20 gallons) when setting up an aquarium or when making water changes (add to new water). So, you could probably start with half a tablespoon or 8g. Equilibrium can be added straight or mixed with 1L of water. When this mixture is added to the aquarium it will impart a slight haze that should clear within 15–30 minutes. Do not use Equilibrium when replacing evaporated water.

I'm in Portland, Oregon and we also have great water with very little hardness and low PH. My LFS sells crushed coral, which I put in a cycling water bottle with water & let it mix. Then add a few squirts to the tank for water changes. Works great.
