Outstanding! A 100-gallon aquarium that is 4 feet long and 2 feet tall can certainly make a wonderful habitat for seahorses that offers them excellent stability and plenty of room to roam as well as providing the aquarist with a very comfortable margin for error.
The nitrate levels (20 ppm) are a bit high and the pH (7.8) is a bit too low, but that will be easy to correct once the aquarium has completely cycled and the biological filtration is well established, and all the other aquarium parameters are excellent, Sue.
Needless to say, I would be very pleased to enroll you in the Ocean Rider Seahorse Training Program, Sue, but it is a correspondence course that is conducted entirely via e-mail, so we must first establish contact off list before you can begin the training course. Please send a quick e-mail message to me at the following e-mail address, Sue, and I will get you started out with the training material as soon as I receive your reply:
Best wishes with all your fishes, Sue!
