Ye, it takes a while to heat up, but seems to be doing the job. In the next few weeks I may be doing a freshwater shrimp jar using the Halstad method so you may see some of that too haha. Maybe photos will be easier with bigger shrimp.
A dedicated forum and online store for the Opae ula shrimp!
I've not heard of that method before, i will have to have a read up of it. These shrimp are indeed a bit smaller then fresh water shrimp but what they lack in size they make up in life length lol, it scares me working out how old i will be when some of my shrimp get to the end of their life. 
Its all about over planting and using them to filter the water, quite interesting. Ye I've heard that. Luckily I'm only 21, so ill be nearing in to my mid life crisis I'm sure!
