This is something that has been in the works since the inception of my tank, but has taken me a while to logistically pull it off. The plan is to provide a full nutritional liquid diet throughout the course of a 24 hour period. The perceived benefits of this are: Natural feeding responses from open water fish Restoring grazing patterns for grazing fish Natural feeding patterns for corals evening, over night and morning Increased pod population as food is less limited than traditional feeding Reduced nuisance algae as the food uptake efficiency will greatly increase Reduced time required to "feed" the tank Here is the setup: Small thermoelectric beverage cooler (6 can capacity) BRS 1.1 ml doser, set to run 1 minute on the hour RO tubing and fittings I have a 1/4" line tapped at the end of my return manifold to bleed off any built up air, especially at startup. This used to just dump in the sump but I now extended the line to the top of the cabinet and then back into the DT centered 4" above my right MP40. This line runs 24/7. The BRS doser will run for 1 minute twice an hour, every 30 minutes and discharges into this line with a Tee. The BRS doser is naturally anti flow reversal (at low pressures) so I don't have to worry about contamination of the food. The 1/4" loops will deliver the food from the doser to the tank. Food will be batched in 6 oz bottles so every few days, I just have to swap the bottle. Bottles will be prebatched and stored in the kitchen fridge. I use freezer packs to provide thermal mass to the mini fridge. This setup will maintain 45F for 3-4 days. Setup is located in the upper right partition of my cabinet 110 Reef Autofeeder by Christopher Sanchez, on Flickr The fridge is too small to fit the doser pump in the fridge like you see with the 1.7 cu ft setups. Doser pump is located to the left. 110 Reef Autofeeder by Christopher Sanchez, on Flickr I can access the fridge with my small door and don't have to open the canopy. Perfect for when in-laws and/or neighbors are tank sitting. 110 Reef Autofeeder by Christopher Sanchez, on Flickr Test stream of water. 110 Reef Autofeeder by Christopher Sanchez, on Flickr Final tubing installed, project the surface of the water by less than 1/4" 110 Reef Autofeeder by Christopher Sanchez, on Flickr 110 Reef Autofeeder by Christopher Sanchez, on Flickr Priming the system and test feeding. The fish didn't seem to mind a all 110 Reef Autofeeder by Christopher Sanchez, on Flickr The recipe is subject to change over time but this was my starting point: Mysis-Feast, 6 ml daily Acrti-Feast, 10 ml daily Beta Brine, 12 ml daily Real Ocean Eggs, 8 ml daily Roti-Feast, 2 ml daily Oyster-Feast, 1 ml daily Phyto-Feast, 1 ml daily Eco Reef Solution, 10 ml daily I plan to increase the phyto-feast over time. I may also look at dosing my Iron Gluconate through here as well instead of dumping 5 ml every Sunday. Similarly, Im trying to determine my tanks daily silicate uptake and I may do this through the food as well. Finally, I may switch to a larger 16 oz bottle and look at dilute the food 50% with RO/DI so that I can do 1 minute of feeding every 15 minutes. Two major drawback to this system is first, the fridge will not cool food down, only maintain cool. So in a power outage, the food will have to relocated to the kitchen fridge where there is more thermal mass or thrown out. Secondly, there is a plug of food between the fridge and the doser that sits for an hour between usage (2 cycles) and quickly comes to room temperature. This is also an outlet for heat loss from the fridge. I will be looking for ways to insulate 1/4" tubing. Also diluting the food and feeding twice will reduce this time. This is all experimental and Im sure it will need some improvements over time. Should be fun to play with.
