How do i start my tropical fishtank off?
You need to thoughly rinse all the items that need to go iinto the tank, It could be the gravel that is causing the gunk, this needs to be rinsed very well. I am not sure whether you have an internal fillter (goes into the water) or an external filter ( situated outside the tank, very often in the top of lid,) If it is external it may have carbon in it and this can leak into the water, It will clear though, an iinternal filter does not do this, either it is an already used filter which will hold stuff from previous use but will clear) anyway, set the tank up after you have rinsed everything (do not used any household cleaners, just plain tap water) Fill your tank up with clean tap water, This need to be treated with a fish declorinizer, (Nutrafin Aqua + is good but the pet store should be able to advise, Then put a double dose of a bacterial suppliment in the tank, (this is bacteria needed to mature the filter, fish need this bacteria to protect them from disease Nutrafin Cycle is good
