converting fw to sw - Aquarium Advice

kingneptune · 08-07-2007, 09:55 PM

Hi all.. I have a 55g Sw tank complete with lr and sand.. I have another tank to put the lr in. I'm going to make the fw tank for a few redbelly piranhas.... How hard is it to convert? any suggestions in general?

Take everything out rinse well and restart. You can not reuse the sand. The filter should be ok as long as you clean it well. Vinegar should help take off any salt stains. Be sure to cycle the tank before restocking.

yeah.. I figured that.. but what about the filter? I have a sump.. can this be used

Yes you can use the sump. Rig it for biological and a little mechanical filtering.

Shouldn't be that big of a problem. You could use your sump. Probably just rinse everything that came in contact with the salt and everything should be fine.
