WTF?

I have just run all my fishtank water tests on tap water that's been sitting out for 24 hours, like the fishfancier forums suggest.



The only difference between tap water and fishtank water 1 week in, is that nitrate level of my tapwater is zero, it increases to tooo much over a week. Oh and sometimes the pH changes.

High nitrate is bad. OTOH, other worrying levels aren't changing, and are nil-low to start with. As nitrate is the last product of the fish-waste process, this is good. It means the overall cycle of fishwaste filtration is working. I think.



I also note that my tap water is really soft. I had thought the softness of my water might have been because I have lumps of pretty wood in the tanks, which soften water, but now I suspect it's probably not having that much of an effect.

Apparently It would be good for the water to be harder. I think the hardness that should be up is KH more than GH. (KH will also stop pH from shifting too wildly.)

~~~

I tested some water from the tank that had a water change 24 hours ago, and I can't see any damned difference in the nitrate level. It should be lower. It's not, expect maybe a tiny bit.

~~~

To do:
1. Lower the nitrates.

2. Put stuff in to harden the water. Oyster shells and stuff. Check with the fish shop.

3. Maybe take some water samples in for testing to make sure my testing kit is accurate.



That's all clear to everyone isn't it?




Frankly, I'm looking forward to getting my tanks sorted. I've been on this learning curve for a while and I am ready for a break.

But I've got at least a couple more days of having two fishtanks on my kitchen table, at least one more expensive trip out for new things next week, and a few more weeks of obsessive testing and adjustment.

Keeping fish sounds like too much mental effort to be fun.

Most of the time it's great.

They do their thing, you watch them do their thing. You just check basic parameters in a relaxed sort of way, and the parameters are usually fine. And life goes on.

Yup. That's pretty clear to me. I used to use specially prepared calcium blocks for fish tanks to harden the water a bit.

Oh good! (I'm glad you piped up on this)
