How to stop pump from blowing bubbles?

[Austin Weinerman]

I have a Rio+ 400 pump for my 20 gallon cube tank. I am planning on adding seahorses to my tank in just a few weeks, but I am having a problem that I'm scared could harm the seahorses. After I do a water change, the water level obviously goes way down, then rises again after I put the new water in. After I turn the pump back on with the new water added, it spits out a bunch of tiny little bubbles for a few seconds, then goes back to pumping water normally. I'm assuming it does this because the pump is exposed to air while the water level is low. I'm worried that these tiny little bubbles could be harmful to the seahorses since they can get gas bubble disease. Does anyone know a solution to keep the pump from spitting out these bubbles after a water change?

No it will not hurt the sea horses and you'll have to age that tank and populate it with pods before getting sea horses.
I'd do some mysid shrimp they seem to like the tiny species that i always use. Never have to add any again if you let them populate and give it atleast 3-6 months

That's good to know it won't hurt them, thank you :) I added a population of tigger pods a little over a month ago, would you recommend adding the mysid shrimp on top of that?

If you can get them it always a plus to have a variety. Plus they're a nice clean up crew also.
Once the population grows they clean more than most realize.
