To be fair this has settled quicker and cleaner then i expected, i only changed 20% and topped up with cycled water.my filter and heater have done the job for now i will upgrade to external soon. most of the plants are in i need some more tall grassy types think vallis. some swords and java fern, and all other stuff from old tank is going in so will be moving it around again. going to run it till the week end as i want to get more cycled water in a do more tests. just unsure on what background to have.may do the rocks.
