Clearing Murky Pond Water After a Hot Spell

A backyard pond turned murky during a prolonged hot period. Laguna Pond ClearFast didn't help. The pond has floating and submerged plants and fish.

Check pH – should be 6.0-8.0. Inexpensive test kits are reliable.
Increase plant coverage to 1/2 - 2/3 of surface area with floaters (water hyacinth, lettuce, parrot's feather).
Use a flocculant + bacteria combo: Accu-Clear (flocculant) plus Pond Market Fizzy Kicks (beneficial bacteria) together clear most ponds.
If unresolved, install a UV clarifier – more cost-effective long-term than repeated chemicals.

Patience is key for new ponds (<1 year); older ponds respond to the above steps.
