PROTALON 707: keep bottles A and B and course days separate
By Richard James · Manufacturer sources reviewed 28 October 2026
This guide concerns the two-bottle PROTALON 707 product. Similar product names do not establish equivalent formulations. Check both bottle labels before using the calculator.

Read one day at a time
eSHa's seven-day plan uses A alone on Days 1, 2 and 7; A and B on Days 3 and 6; and no addition on Days 4 and 5. The PROTALON calculator keeps the quantities separate. Never add every row at the start or measure the combined total from one bottle.
Important setup checks
- eSHa warns that aquatic snails may be killed and says to remove them.
- It directs stopping CO2 injection and fertiliser additions during treatment.
- Ordinary filtration stays running; check the listed active-media and UV exclusions.
- It does not recommend concurrent eSHa treatments and restricts other-brand combinations.
No guaranteed algae-free deadline
A completed calendar does not prove that the original cause of an outbreak has been resolved. Keep photographs and records of lighting, maintenance and the changes actually made. This guide does not promise complete clearance, universal shrimp safety or unaffected water quality.
Before repeating
The manufacturer describes additional circumstances and aftercare beyond the standard plan. Read those directly rather than treating the calculator as an automatic repeat instruction. If your bottle or response does not match expectations, obtain clarification before adding another course.
