Cat litter & John Innes No1 substrate for Nothobranchius guentheri

JI composts contain lime so be aware that if you need to have a lower pH it will be difficult to achieve. A better bet would be Westlands Citrus Compost, whose pH is around the 6 mark and is lime free. The cat litter is just ok. I used it on my aquanano 30, but it needs to be pretty deep to be able to plant in easily. I don't think I would use it again on it's own as a soil cap anyway.
Cheers

Cheers rod, I'll be using rainwater but that probably won't be enough to lower the PH hike of the JI. I'll check the Citrus Compost out.
 
I tried the exact same thing Robbie, and my pH is around 7. I'm hoping to use some peat pellets to help drop pH a bit.
