Yes, you read the last post right- I am planning a new tank build. I have always loved seahorses but they have some specialized needs that I wasn't ready for until now. I am going to purchase a 30g XH. Because our home does not have AC I need to connect the seahorse tank to the existing tank since it has a chiller. My return from the 36g splits in 2, one half goes thru the UV and one half goes thru the chiller. If I divert the half from the chiller into the seahorse tank but have the controller probe in the DT there may be a degree or so difference in the 2 tanks. That way I can set the temperature at 74-76 which should be OK for both tanks needs. When my fish have all been settled in and I am positive they are disease free I will unplug the UV so as to not kill any beneficial pods or phytoplankton. I hope to have some photosynthetic gorgonians and maybe some easy sponges in the seahorse tank along with some macro algae. I will probably run a skimmer on the seahorse tank too to deal with the nutrients since seahorses are messy eaters. I will definitely buy tank raised that are trained on enriched mysis and after they are eating that well I will offer them some newly hatched bb at times. I'm taking my time with this build. I need to cycle some dried LR I have and maybe add the macro algae and some sold corals first. Then when everything is very stable add the ponies, 2-3 seahorses. I am so excited about this!!!!
