Hi, I have recently purchased a custom made tank 1800mmx500mmx500mm that holds between 400 and 450 liters.
I have purchased 2 300watt heaters, 2 large bags of brightwater stones and 2 large pieces of briftwood. I have completed building the stand this weekend so was keen to get the aquarium setup. I have not yet purchased the filter for this aquarium mainly because I was not sure what I needed for this size but I did have a Fluval4 and a Hailea BL1000. I decided to use these and get started. There are no fish in the aquarium yet but the plan is to move the fish from my three smaller display tanks into this one so I can use the smaller ones for breading. I washed the sand untill the water draining from it was clear and then I washed the driftwood. Once in the aquarium I slowly filled it and then added the heaters and filters. For the first 4 hours the water was clear and then over night it went a brown cloudy colour. Now to the questions.
Could this be from the driftwood?
What filter do I need for this size aquarium?
