Hey guys ...as a high school senior I've taken advantage of senior privileges and chosen breeding crystal red shrimp in a planted habitat as my senior project. Cool right?anyway I need advice because I've only done cherries and I'm lackluster when it comes to monitoring my water chemistry and properly balancing an aquarium. I've got my hardscape down. Utilizing seiryu stones and Amazonia aquasoil as a substrate. I've got 2 13watt power compact lights above it. I've acknowledged the need for a heater because it gets cold in a high school biology lab. I've decided to go with an eheim jäger 25w heater. I'll try to do a simple iwagumi with hc and dhg. I won't be using co2 because I honestly can't afford a system and I can't monitor it closely because it will be at school. I also don't want to risk gassing out s grade crs. Can't afford that either. I'm concerned that the hc won't get all the proper nourishment without co2 under the two fluval lights.
