I have a Fluval Spec V I'm currently cycling. It's fairly heavily planted-- did a dry start with Dwarf Hairgrass and Weeping Moss, and added c. parva, s. repens, c. undulata (yes, I know it'll outgrow the tank), Lysimachia nummularia, Microcarpae minima, and a buce species when I flooded it.
Dosing is almost an every night thing. The plants can take a 2ppm dose of ammonia and the next day it's between .25 and .5 ppm
. I'm used to using plants to do what amounts to a fish-in cycle in my large tanks-- plant heavily, seed the filter with established bio-media, and stock extremely slowly. I didn't count on it happening in the 5 gallon. I'm assuming it's the stem plants that's causing the rapid consumption of ammonia.
So. Here's the question. I intend to start with 15-20 neocardina shrimp. Will that produce anywhere near 2 ppm
of ammonia? Because I have a feeling that with the rapid processing of ammonia by the plants and the small number of shrimp I'm starting with, the tank is ready to go.
