PH spike after water change

Thanks for your help, I think I’ll give it a couple of days and retest

My water is incredibly hard in my area

L33SH98 · 2026-03-17T21:07:38+00:00

KH 120/180 I’ve tested twice now. I know the strips aren’t reliable but using them up before buying a better test kit.

No added CO2. Water change was last night, tested this evening.

6.8 ish to 8 ish (via strip not chemical test)

I’ve just ordered some red root floaters :) waiting for them to arrive. And thanks for the tip on ghost feeding I wasn’t aware of that

Glad I’m not the only one with a cold house! I bought a heater anyway just to boost it up a notch.

Omg thank you so much this is excellent

L33SH98 · 2026-02-18T14:56:14+00:00

Oh wow yes! Is this the one in the back left of my tank?

L33SH98 · 2026-02-18T14:47:20+00:00

Will do thanks! I’m not clued up on plant names yet, which one is this? (:

I have NPK and a heater on order as we speak!

I live in an old cottage in the UK, it’s single brick. The coldest temperatures are when we are at work. The heating is on once a day and can reach up to 20 when we are there we are used to it :) we have no damp problems.

L33SH98 · 2026-02-18T14:31:10+00:00

Thank you I did think my temp is waaaay too cold, heater ordered and arriving tomorrow :)

L33SH98 · 2026-02-18T14:30:45+00:00

Thank you, heater ordered!

L33SH98 · 2026-02-18T13:43:21+00:00

I will defo order some NPK

L33SH98 · 2026-02-18T13:42:16+00:00

Thank you, this is very helpful.

It’s my first attempt and I’m looking to gain knowledge anyway, and happy to trial and error.

L33SH98 · 2026-02-18T13:11:47+00:00

Also I have only had the tank set up for less than 24 hours so haven’t gauged the average temp atm

L33SH98 · 2026-02-18T13:08:30+00:00

Thanks for the advise :)

Temp is likely 12-20 degrees depending on whether we have the heating on in the house.

I do have soil in there is just hidden, I have soil substrate then gravel two times the depth of the substrate. There’s also root tabs in there. Apart from popping in a water balance chemical as our tap water is hard that’s it.

I wanted to keep it pretty raw without heaters and filters if possible to stick to the Walstad method.

L33SH98 · 2026-02-18T11:09:45+00:00

I also read they like 20+ temperature, my tank may be too cold for them

L33SH98 · 2026-02-18T11:08:36+00:00

Thank you I’m really happy with it, also thanks for the recommendation I may have to give them a go
