Good deal, I know my pump is 137GPH, very odd numbers I must say. Reason I asked that is because for seahorses it seems somewhat strong, I've seen someone on youtube with a seahorse he called "Hurricane" which I can only assume he named it so because it blew around in the current, which is obviously wrong. Glad to see you're doing it the right way, I see too many who don't, and with such a delicate and beautiful creature it's hard to see.
Keep up the good work, those horses deserve a good home!
