Iwagumi Style - Troubles of having thick substrate
Hi Everyone,
I have a question about running Iwagumi style tanks and the problems you could run into with thick substrate.
I'm planning on putting sand in the front because it's fine and ideal for the carpeting plants. I have Seachem Flourite gravel to cover the back areas. Some of what I want has some of the substrate around 6 inches high. With gravel, and the plant roots it will help maintain things, but I am still worried things may not go as planned. I'm concerned about anaerobic bacteria getting out of control and not having enough water flow through the substrate.
I have never done substrate thicker than 4 inches and never done this style of tank before. Thank you for any advice ahead of time!
Attached is an image of a 75 gallon plan for this tank.
Lightest Brown - Sand 2-3"
Brown- Flourite 3-4"
Dark Brown - Flourite 4-6"
Grey - Rock
Water Parameters:
dGH: 6-8
pH: 7.2-7.4
Nitrate: 6ppm out of tap
This will be a 75 gallon tank with a SunSun HW-505A running on it.
