Hi folks.
I learned how to visualize flow from Than from this Tidal Gardens video. This helped me with setting up the torch garden and eventually the sps tank. I don’t use mp40s (I’d rather spend that money on the lights). As sps grows out into colonies, you’ll end up buying more powerful or additional powerheads to circulate water around the tank. My observation so far is that sps prefer gyres as it’s indirect flow and a sheet of water flow atop the tank. Two gyres that are opposite will crash into each other and flow down and around colonies which leads to longer PE, provided your parameters are set up correctly and the corals are acclimated.
Most of my PE happens at night (I run down to look at the tank two hours after lights out excited to see it). I feed pythoplankton, CRT concoction and benereefs at times. I also dose KZ acro flow and KZ Coral Vitalizer which probably helps as well.
Here’s some of my sps directly under my gyre and experiencing flow.
There are many ways to achieve flow and probably employ a different strategy than mine, but the important thing is to be able to visualize how it looks like in the tank with the air stone technique. Seeing how the flow circulates in the tank was probably the best thing I did for my sps.
Hope that helps. I only learned how to keep sps the past six months from zero knowledge if that helps. Flow for sps is easier than torches too.
