Jaime's shrimp is the exception to the rule. its born out of titanium and bulletproof
if you must do a water change, do smaller volumes over several days to minimize the impact... having said that, i just did a 60% change with berried CBS and PFR's last night. haha... the water was exceeding 250ppm tds so i brought it back down to 130. everyone's still berried this morning but its just something to be careful of. I know most of the TDS is likely due to my overfeeding and waste.
congrats on being a grandma!
