Hey y'all! So my 75g with fish is still cycling and making great progress. I also have a 5g cycling without fish which isn't doing so well. Today the PH on both tanks dropped to 75g 6.6 5g 6.0 from a pretty consistent 7.4. I checked the KH & GH levels and the KH for the 75g 35.8 and the 5g 17.9. The GH levels are always 300+ due to where I live.
I did a 20% wc on the 75g and a 75% wc on the 5g. PH for both are back to 7.4.
My question is regarding the KH. I did a little research and know that it's a buffer that helps keep the PH at a consistent level. All the other info I read as far as fixing it has me a little confused. So I thought I would ask the experts.
Why would the KH drop so low and how do I treat it?
TIA and happy fishkeeping!
