Researching Coral needs..I read Low/Medium/Moderate/Strong Flow rate.
Any ideas how to judge that as a beginner?
Thanks
wondering if it is enough..or maybe a Power head?
That totally works for me...One of the HOB filters is splashing and getting spatter on my floor,I dont really have room for both HOB filters and my skimmer...any input on the size of the power head or heads?
Thanks
Here’s a rough idea. Take the volume of your tank and multiply it by...
10-15 for “low flow”
20-35 for “medium flow”
40 and up for “high flow“
If you’re running a sump, you can also add the flow from the return pump. Keep in mind it will usually be a much less than what the pump is rated at due to vertical pumping losses.
Also, I am assuming because you are running HOB's that you are not working with a sump or anything. I would look into something like this https://www.bulkreefsupply.com/larg...-refugium-with-led-lighting-cpr-aquatics.html for the future to replace the HOB's filters all together. Now I am not saying you won't have success with the HOB filter (honestly I don't know enough yet or ever used one), but everything I have researched shows that a well maintained refugium will out perform both HOB's and canisters. Especially when you can get creative and still use the same media you would in those filters (carbon, filter floss, etc.).
I went budget...was just getting my so called feet wet for a Valentines day gift from my Wife...now I'm hooked..lol
I went from planning on spending a few hundred bucks...I'm now in over $1500.00...and we dont care...she loves the tank...lucky there
As @Crustaceon mentioned above
I would definitely go with the highest rated for your 75 gallon, so 75 * 40 = 3,000. That being said that's TOTAL GPH not just what you should aim for in powerheads. So make sure to include what your HOB's and skimmer are pushing. Also, if you remember how much actual gallons you put in your tank (water displacement from sand/rock) may be more along the lines of 60-70 gallons depending on how you stocked. So work that into your math. And do it in multiple powerheads so you can create those random flow patterns and then just work on your placement so you get different rates in different places and are not blowing sand everywhere lol
Hehe, yep I tried going on a budget too and that did not pan out once I got started lol. I actually started a 20 long nano reef, and within 3 days I had upgraded to a 36 bow LOL. And so far I have
Mind you, that was all bought after I started the budget build with a left over 60 gallon canister filter and Maxi-Jets pumps I had laying around from the one of many freshwaters I have up lol. So I ended up putting in like another $800 in just that stuff
- The CPRAquatics HOB Refugium /w Rio 400 pump
- XPAquas Overflow Box that does surface skimming and is an ATO (Auto Top Off)
- Tunze DOC 9004 Protein Skimmer
- 2x Koralia Nano's 240
- Orbit IC LED's
dang...350 gph HOB...protein skimmer and 4 Power Heads...are my frags and fish gonna be able to live?..lol
