John was able to keep both the lower and upper tanks warm and stable during the past two winters. The fifty gallon plastic barrel on the right of this picture has been wrapped with the pipe and covered with clear plastic. The barrel will be insulated next. This barrel will be John's heated tank for making up new Instant Ocean. The upper tank is made from white plastic and this has worked very well.
Light reflects from the bottom and sides of the tank.
This was our first wide shallow grow-out tank. The light rack that is now on the upper tank was used on this system for two years. We were able to grow out hundreds of corals with eight - 40 watt bulbs. John is interested in producing large numbers of valuable Zoanthids so he can expand his production of live rocks. Zoanthids can be sold to wholesalers in regular shipments.
