A compact and affordable wavemaker your tanks needs to achieve great flow!

We’ve been using the Jebao SLW-10 in our 15g tank, and the flow has been great. You can tune the flow to your specific needs with its built-in controller.

Tank Size Recommendations

SLW-3: 1–10g

SLW-5: 5–15g

SLW-10: 15–30g

SLW-20: 30–50g

SLW-30: 50–90g

So, I finally broke down and bought some Hanna Checkers, I've been in and out of the hobby since the late 80s and have always relied on titration tests but with my latest system I have not been able to nail down my parameters, I tested one number and my LFS with my own test kit tested a wildly different number. I know these test kits vary wildly from manufacturer to manufacturer and from user to user but my own back to back tests were all over the place. I know Hanna tests have variations but for me and my old ass eyes it's much easier to read a digital number display than try to distinguish between shades of pink, blue and green.

Anyone try out the AF4 from indaquatics? With Apex?

Curious if anyone can tell me thier experience with this product. I also have lots of questions about the config if using Neptune Apex w 0-10v cable. Can you shut off pumps, skimmer? How far (up to tank) can this pump? Have to be return pump?

What are everyone thoughts on the Red Sea test kits?

Is my skimmer venturi sound normal??

Xyclone PS-370 Protein Skimmer

Can someone please help me get these bubbles to not leak out like they are.

IS A GLASS HYDROMETER ACCURATE

I've been using mine for a year and a half

I was looking to get the Tropic Marin High Precision Hydrometer.

Tried out a new lens port attachment today — it clips onto the phone and lets you take photos right through the water. 📸🌊

The detail this thing pulls is way better than I expected. Excited to test it more and start sharing some cleaner, sharper reef shots with everyone here!

Anyone else using one of these yet? Thoughts

Hey everyone! 👋

I’ve recently finished working on a project that might interest other reefers — it’s called the Marine Assistant Mini! 🐠

It’s a DIY add-on controller for reef tanks that gives you extra control over equipment and sensors. It’s got:

⚡ 2 switchable 12V outlets

🌡️ 2 temperature sensor inputs

💧 Float and leak sensor support

🔌 Expansion ports for future add-ons

It’s designed to be easy to build, with guides and videos to help you along the way. Home assistant is used and required.

Would love to hear what you think — always open to feedback or ideas for future modules!

Comment below any other app improvements you would like me to make 👇

Dusting off my AI Prime was probably not a good idea over my tank 😄. Will have to take my lights down at night and properly clean them. My AIs have been running strong for 4 years now!

Anyone use this light if so what’s the best setting for it
