OK so i need to know, why do we change 10% of the water in tropical fish tanks a week?
Why not do 20% every forthnight?
or 40% every month?
Or can i do these things and i just didnt realise?
why is it 10% too? can i do 20% a week? or most of the 200 litre fish tank i have every week, say 50%...
I completly agree with you on the 1" per gallon thing, first of all, i had a reedfish which was about 14" long, but that doesnt mean it needs 14 gallons of water all to itself! i buy my fish from shops as you can haggle for the price, and also you can see whether the fish would be too cramped in...
I'm looking to buy these fish, I'm in the UK in middlesbrough but i dont mind travelling if the price is right. no further than 30 miles.
10 points to best answer....
I.E. the one i buy stuff from :D
