Matt should answer this, but i think the tank should cycle at least 8 weeks . Read up on the nitrogen cycle,you have to establish your biofilter first. get an ammonia test kit and nitrate, ph and so on .and do a lot of reading. Seahorse are not easy to keep they are a lot of fun, but learn how to care for them first before you get them. if you already have them and need help Matt can help you he's are seahorse whisper...
