Working on converting my 600g pool in the basement to a tropical one, normally I use this to house my koi in the winter but my RTC and TSN are going to be moving into this as soon as it's ready. Basement temps are in the 60's. So is it worth draining this ENTIRE thing (I've got koi in it right now) and putting insulation on the floor or is it a waste? Just checkin before I waste a weekend on this.
