Archer fish and mollies prefer a ph of 8, they should do just fine.

Your mollies will be good at pH 7.8 or 8, but the tetras won't like it. I wouldn't lower it below 7.0 for the mollies' sake, but you could lower it a bit. Use peat in the filter. As I expect Lupin will mention (and can explain better than I can) the hardness will have an impact on lowering the pH but peat is safe, but don't go too far.

Don't use any chemicals, they do not last (the water buffering makes them inert in the long term) and the fish will be harmed with fluctuating pH levels. It should be done gradually and slowly, over days, if you do want to lower it a bit.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I sent the last reply before I noticed the thread continued, sorry. Is this the same tank that has the cloudiness mentioned in another post?
