First time poster, so please forgive me if I forget to include any info you need:
20gal long mod-heavy planted tank
Floramax and Black sand for substrate
Have 3 brilliant rasboras, 2 pygmy cory cats, 2 endler hybrids
Several dozen shrimp (neocaridina)
Ph fluctuates between 8.2-8.6
I use Seachem Prime and Flourish - weekly water changes
Other tanks in the house with similar substrate sit around 7.6- 7.8 or lower
Have tried adding driftwood and cholla wood, minimal temporary changes to PH- goes back to sky high
Ordering some catappa leaves today, but wondering if there is something I'm doing wrong?
If I need to use a product to stabilize, I'm willing to do so, but could use some advice on how to safely and gradually lower PH using said product.
Please let me know if there are any other details I can provide! I appreciate any help or guidance.
