TRAGEDY AGAIN!
Hydroids are winning the battle,they regrow faster that the every two day mowing.
When
larvae molted to Z6,they looked not so many.I could see about 50 of them.Now they molted to Z7,at 20 days,and I had a massive die off.
So I scooped out the survivors,(only freaking eight

) and emptied and cleaned the tank.
Playing again the stupid little indians game!
Always larval mortality coexists with hydroids bloom.Don´t want to be paranoic but suspect both facts are related.As my system is contaminated with hydroids,it will be a recurrent problem unless I shut off and sterilize the whole system.But because Lysmata
larvae take up to 5 months to settle,I must compromise with a less radical aproach
Ups and downs all the time!.You can´t get bored with this hobby!
