have added a bigger tank - no problem (beside that expensive recipe).
but maybe you should say what you want to store in these tanks, and i add a recipes that rapes/use your fluid-storeage - so your tanks should be quickly empty

@hoho
it's not realy a fraction, it scale very linear - just see 1 x steel = 10 iron-plates - but it was cheaper -> yes if you ignore the pump. all fixed i think with next version. of course new stuff for discussion also added

i did not realy understand why people would use very big tanks. little bigger to save space yes - but very much bigger ?
