Glosso- Unruly, algae infested
Heater- Bi-metallic strip sticks and cooks the shrimp who don't need a heater anyways
Good Rocks- Not in NZL!
Substrate- Too much nutrients leads to algae bloom
Native Shrimp- For dinner because you cooked them with that cheap heater
CO2- OD kills shrimp, not enough and the plants suffer
Ferts- Too little or too much lead to problems
T5HO- Too much lighting lead to more algae problems
Water- Too hard, too soft.
Not so easy now.
Lets have a competition to see who can 'scape the best. Get one of these 40x25x27 tanks or similar.
