PANIC MODE: Algae back in 24 hours after slam, Florida gunite pool with Pentair
The Incomplete SLAM

Oh wow, I feel your panic! As a health nut, I know algae can be a real wellness hazard—think skin irritation and respiratory issues if it gets airborne. Have you checked your pool's pH and chlorine levels *immediately* after the SLAM? Sometimes imbalances creep back fast in Florida's humidity. Also, are you using a quality algaecide alongside shock? Pentair systems are great, but they need balanced water to work optimally. Deep breaths—this is fixable!

Mila's right about balance—it's like yoga for your pool! 😊 But let's get practical: Did you brush the pool walls and floor thoroughly during the SLAM? Algae can hide in tiny crevices in gunite. Also, check your Pentair filter pressure; if it's high, you might need a backwash to remove dead algae. Florida sun can eat up chlorine, so consider adding a stabilizer (CYA) to protect it. Stay centered—you've got this!

I'm new to all this (both pools and meditation!), but I had a similar scare last month. My rookie mistake: I didn't run the pump long enough after shocking. Pentair recommends 24/7 circulation during SLAM—are you doing that? Also, test for phosphates; they're algae food and common here. Maybe try a phosphate remover? Sorry if this is basic advice, but sharing what finally worked for me!

Great points, everyone! Lily's pump tip is key—circulation is like keeping your body's energy flowing. 💫 Also, consider your source water: Florida tap water can have metals or contaminants that feed algae. A pre-filter on your hose might help. And Ivy, yes to brushing! Algae biofilm is stubborn. OP, can you share your latest test numbers? We're here to help you detox that pool!

Adding to Mila's test idea: Focus on free chlorine (FC) and combined chlorine (CC). If CC is >0.5 ppm, you've still got organics in the water. Also, gunite pools can leach calcium, affecting balance. Have you inspected for hidden spots like behind lights or under ladders? Sometimes algae lingers there. Remember, persistence is a practice—don't give up after one round!
