hm well I have a 20g tank.. I mean I could take water from there, but that would be like... half the tank
Soo if I did do that, I would just be doing a nice big watercahnge on the display tank... ?
I have an Aquaclear 150 (small) on the 20g.. it has ONE small piece of sponge in there, but it hasn't been in for very long.. 3 weeks? maybe longer.. but it's fairly small.
I need to get a heater, 10g tank (can all 4 of my fish go in there?) , my hydrometer (will this work?) .... and something for flow... ?
How hard is it exactly to do the hyposalinity with a hydrometer.. makes me a little nervous.
