so after a full day of doing 75% water changes the water is still murky, but less brown. We were stirring up the sand as much as possible and then doing the water change.
I was wondering when it would be safe to do the switch. Since we're keeping the old decor and filter hopefully it will sharpen up the water much quicker, although we'll be watching the water very carefully for spikes in ammonia, nitrite, nitrate. I bought a bottle of seachem stability for the hell of it, even though I think the product is a gimmick and I probably got ripped off.
I guess I'll run through our scenario. We're switching from the 45gal to the 60g. They are right next to each other. This was my logic in pulling off the physical switch: (computer scientist goes aquarist)
When temp, ph of new tank = temp, ph of old tank:
1. Unplug everything.
2. Move filter to new tank
3. move plants/decor to new tank
4. syphon half of old tank water to new tank
5. move fish to new tank, avoid netting them, just trap into cup and move.
6. stress guard (seachem) the new tank
Since we'll only be reestablishing the substrate bacteria, would it speed up the process to take some of the old tanks substrate and put it in a flat tupperware container and lay it on the floor of the new tank? Logic here being that the bacteria would somehow transfer to the new substrate (via floating?)
I've included some pictures of the murky water. When would you think its good? photo(2).jpg photo(3).jpg
