I got the same random flow generator with the drop down adapter. Every so often it seems to suck air in from the surface making a weird noise and blowing air bubbles for just a second. Have you experienced this?
Updates:
Clownfish:
Added another Fancy White Extreme and a Fancy White Gladiator from SA! They're from the same clutches as the first two. Now at 7 clowns. Aggression is low, and they are all eating well. Keeping an eye on the largest Fancy White Gladiator (the one I got in the first batch of two). He's kind of larger than the others and a bully. I'm surprised the bonded pair has totally mellowed out since I gave away the larger Vivid Fancy. I'm thinking of selling the larger gladiator if he keeps being a bully.
Cloudiness:
The tank has been 100% clear of cloudy bacteria since the UV was on. It cleared up 2 days after running the UV. I have had it off for 48 hours now and tank is maintaining it's clear look. I'm optimistic I can remove the UV completely out and not have to turn it back on.
Skimmer:
Switched out my Simplicity to the NYOS Quantum 120. So far these sound is better, and it's skimming! The Simplicty struggled, especially because I had to close the wedge pipe completely and skim as wet as possible to get it to do it's job. NYOS seems totally fine and now skimming nicely after a week. I'll probably take a photo soon.
Vivid Creative Aquatics Random Flow Generator Nozzle:
I ordered the new @Vivid Creative Aquatics random flow generator nozzle, with the red sea adapter kit in 1/2" size. They are a new sponsor on R2R. I was excited! After opening and installing, which was really easy, the adapter immediately sprouted leaks. A lot. The plastic seems a bit cheap and light. The finish on it is really not great, almost like it was just 3D printed out of something that's not very heavy duty. I guess I'm used to nicely manufactured PVC or acrylic, but this is kind of cheap. I'm guessing when the 3D printer layers on the plastic to make the tubing, it was just too thin. The idea is good, the execution not so much. I sent in a support email to see if I can get a replacement. But it is concerning because there was no damage to it, so it just came that way. The Quality Control isn't doing a quick water test, otherwise it would've been instantly clear it doesn't hold water. Hoping the replacement works, but skeptical on the quality. I hope I just have a dud.
