Reply With QuoteI'm using Dymax black pebbles. After using, i suspect the pebbles are on a higher Ph than 7. This is because i used peat to lower the aged water before top-up.(Ph5.9~6.2)
I have encountered shrimplets in my eheim canister because i'm using undergravel filter method. I suspect the shrimplets managed to slip through the small pebbles that i used for the shrimp tank. (3-5mm size) If i add black quartz, will it helps?

I placed breeding box with "HELP" soil in the tank to lower the PH. It works but a bit ugly. No choice as i'm keeping fire red shrimps.
Hi stone pot,
Changing your substrate to a finer type may prevent shrimplets from getting through but may also reduce waterflow through the UGF. Some folks actually use a shrimplet proof mesh on the UGF before laying the substrate on top.
Test the pebbles by dripping white vinegar on them. If there's fizzling, the pebbles are alkaline and likely contains carbonate that will increase pH.
Yes, you can counter the increase in pH by placing acidic soil or even peat directly inside the tank. Just don't overdo it and know that you will have to monitor and change the peat/soil when they are exhausted.
Lesser shrimplets in the canister after the dirt settled down in the gravel. Now waiting for the gravel to get mouldy and hope it stablizes the PH. So far so good. A few hundreds of shrimplets (up to 1.2cm) in my 3 ft tank. PH between 6.8 to 7.1. TDS below 250.
