Hello everyone!
I'm currently cycling my 32.5g fluval flex and was thinking about possible filtration upgrades, including a refugium. I bought 2 intake media baskets and was wondering if i could turn one of them into a refugium with filter floss in the top compartment and then the bottom 2 compartments combined into a 4"x3"x5" space for a refugium (~1L of space).
The other media basket i was going to have normal filter floss, activated carbon, and biomedia. I was thinking I could lodge a bag of biomedia at the bottom of the filtration unit a couple inches from the pump (there's a fat open space at the bottom of the filter box in the fluval flex that's 8" wide by 3" deep by 4.5" tall).
My questions are if this is a good idea and if so, what a good light would be (submersible or one against the glass in the back of the filter back) and how to set this up. I've never made a refugium before but I plan on maxing out the livestock of the tank including a small pufferfish so I would like to optimize my filtration as much as possible.
My current equipment:
- 2 media baksets
- 2 bottom blank inlet covers
- 2 top shrimp proof inlet covers
- 2x wave maker (Jebao SOW-8) [will get another one soon]
- Tunze Comline 9001 DC skimmer
- SICCE Syncra Silent 1.5 pump
- inkbird itc-306a wifi temp controller
- fluval m150 submersible heater
Thank you so so much!
