Grow corals faster with elevated reef tank parameters? | BRStv Investigates

If you add more Alkalinity and Calcium to your tank, will your corals grow faster? In our last test it did, so we are trying it in a couple of real world reef tanks like we have in our own homes! Today we check in on elevated reef tank parameters and see how they're growing.

Today on BRStv, we have a brand new episode of our series, BRStv Investigates. In this series, we explore popular reefing theories, products, methods, and what the manuals are missing, with a focus on putting them to the test! Stay tuned as we explore even more reef fantasies and reef certainties as we try to dive into common hobby questions and challenge long held ideas in order to make this hobby even more fun and easy!

Can you please tell nutrients level for both tanks.. Bcz nutrients level also play great role in growth of corals n colors too

[@andycx2]

Yeah there is no mention of nutrient levels even though its common knowledge that if you have a high Alk but low nutrients levels you end up with burnt tips etc

[@ajsreef1034]

Awesome test guys. Keep up the good work!

[@davidmiller5832]

Awsome information! Again you guys are setting the bar with real world results!

[@_mal7887]

Awesome Vid! Thanks Guys!

[@greetingsearthlingspluto6666]

I use elevated levels as well and our corals are doing great. Thanks for the informative videos as always.

[@atfinthehouse8631]

These studies / investigations are great. Not always sure your conclusions are spot on. But overall a really good job. I think here your see various improvements of growth in different tank parameters for different corals.

[@atfinthehouse8631]

The actual reef tank evaluations are great.

[@FuNnY71818]

Where are the no3 and po4 running at in each of these tanks?

[@HollaAtChaReefBoy]

Great video!!! I currently run mine at semi high level with ALK at 10 from day 1 of the tank setup, which is running about 8 months now. Coral growth is surprisingly fast! Love it!

[@ramachandran6342]

Cal n mg level??

[@atfinthehouse8631]

Fantastic when you give the run down of all the inventory. It would be even better if the costs are provided. Coral growth looks great and remarkably different. Wonder how many reefers can just look at their tanks and know what’s going on. What to add, what to subtract and when to test, change media, which media to use, how frequently to change. When to water change.

[@pkfkkknk]

Meaningful growth at the cost of doing so (including money for the 2-part and risk). I’ll keep mine at the current levels. :)

[@tyrell2695]

I'm honestly thinking about switching my tank to higher levels. The colouration is insanely good and they just look happier.

[@MS-vp8ex]

What about tanks that use carbon dosing. Could we run dkh at 9 or 10 instead of the recommended 8?

[@twinturbo111]

How do you acclimate a new store-bought coral that was sitting in 7dkh into an elevated tank with 12dkh ? An 1 or 2 hour drip wouldn’t be sufficient ?

[@Phangmaster]

12 dKH is super high, I personally aim for 10, anyone who wants crazy fast coral growth clearly isn't thinking ahead!

[@jasonamandamccullough9049]

What light schedule are you running on the XR30? What is your template? Can you post the template to download? Thanks guys.

[@hediki]

Would love to c a control tank: std dkh w/ ph dictated by ambient co2 lvls vs high dkh w/ ambient co2 and high dkh w/ 8.4ph .

[@computerr2000]

Could you please do a 4 photos screen shot. Comparing high to low setups without also seeing the daseline. Of when the corals were first put in is kinda not a fair comparison.

[@TheTrevor40]

The problem with this test is there are vermatid snails in there irritating the corals. You can see certain corals not encrusting to stay away from them.

[@lawiez]

started the hobby thinking higher was better, now i'm just happy at 8dkh, 420 ca and 1250-1300 mg. tip for newer reefers, stability imo is the most important for accelerated coral growth. elevated reef tank parameters would definitely be for someone with intermediate and advanced experience!

[@justforkiks29]

What is the temperature of both tanks during the study? I run elevated levels and have found that when tank temp is raised it helps consumption of elements.

[@careysoutherland8291]

great video but you guys didn't give any pictures of the corals when they where first placed in the tanks. needed before and after for high and low levels.

[@garyperrine3619]

Can you start with higher levels why starting cycling or adding fish or coral do these levels effect fish? Thx

[@dontreply8346]

BRS I NEED YOUR HELP! Just found out my building is getting fumigated in 10 days and I’m stressed about what to do with the fishies? Is there anyway I don’t have to break down the entire tanks and catching all the fish? Is there a healthy way to leave them in the tanks during the vikane treatment? This sucks

[@stevenfountain84]

How would this work with soft Corals.

[@Reef-Tripp]

No3 and Po4? , please

[@greennavy2006]

What about doing an experiment Running a calcium Reactor with minimal 2 part dosing with .........or With Kalkwasser compared to the stand alone 2 part Dosing... Some adavance reefers use Calcium reactors as they are doing SPS dominant tanks!!!!!!!!

[@wolfmanjack3451]

How are the fish and inverts on higher levels? My kids love the clownfish they named them,lol I don't want fish strung out on stressful water perimeters.

[@danielsmith1383]

Hi Randy How are the coral colors? Any difference between the two tanks? Reason I ask is, I use full AquaForest on my tank, and they claim that dKH of 7,3 - 7,5 results in better colors. Can you confirm or deny this? Best regards Daniel, Denmark.

[@danielsmith1383]

Thanks. Looking forward to see the progress and if the colors will suffer with a higher dKH

[@octapusdude629]

Hi Randy How long does the silicone last in a new tank ? Is it true that 10 years is time to think of changing the tank? Is it true that clear silicone has more silicone than black Because of the pigment that makes up the black color? Therefore making a clear silicone tank last longer? Lab test time?

[@Daan6661]

I’m downsizing to the same set up. Assuming you run the ab+ schedule, at what intensity do you run the xr30 with the diffuser?

[@budgetaquatics8506]

What was your nitrate and phosphate levels in both tanks?

[@daviddistefano9508]

Was there a common difference in tank pH? Or were they similar?

[@abh3960]

I have a 20 gallon lps. And 38 long mixed reef. What should alk. Cal. Be may I ask. For growth.

[@BRStv]

We normally suggest 9 dKH, 450 ppm calcium, and 1300-1400 ppm magnesium as it's a nice middle ground between growth and giving you some wiggle room for potential mistakes. If you wanted to max out growth and are ok with the risk, keeping elevated elements like discussed in this video mini-series is likely going to be your best bet.

[@arcticvox4149]

Can you make a reef tank using a very old aquarium like 40-50+ years old, my grandpa won't let me because it might break

[@joe0813]

why do most of the acros look bleached though?

[@metalldanny]

How long does it take to get Coral line ?? (New Tank,) ThaNks in advance

[@jackson7962]

6-12 months if you have good calcium and Bicarbonates. Use kalkwasser in your ATO

[@metalldanny]

@@jackson7962 ThaNk you for the answer!

[@metalldanny]

@@BRStv ok thank you very much for the reply 😀😀 Patient patient patient ⏳

[@louisgenin1038]

Am I the only person shocked by the 600% increase in alkalinity dosing in the high level tank... The difference in growth seems minimal. Something doesn’t quite add up

[@theskeletonboi]

Parameters in the tank like Alkalinity, chemically buffer with other components in the water.

[@rwrajitha]

ARE there no updates to this? You guys mention that you want to run it for a year with updates. How did the Fish in two diffrent systems fair over 1 year time ?

[@BRStv]

Those systems were recently taken down. I'll have to poke Ryan and Randy for an update video :)

[@Kanoa440]

Was pH the same in both tanks? Would think pH was higher in the elevated tank, contributing to the increased growth and consumption.

[@Kanoa440]

You guys are so smart. I look forward to next test!

[@duraticatereef1003]

I knew it. I ran my mixed reef this way for years. Everyone thought i was crazy.

[@svetliopopgeorgiev2999]

I see you enjoyed the sunbed that day 😂😂

[@hunterh891]

Is that really "low level" though I mean for most the low level is probably what we"average or new reefers" would shoot for. Sorry I heard what you said at the beginning saying that the " low level is what average reefers shoot for."

[@TheDashCave]

What were the exact levels again?

[@lchamp7946]

Levels provided at 3:41.

[@Mike__B]

It's this kind of extra effort your company puts out that makes me continue to purchase products from you, even though stupid court ruling means you now need to collect sales tax on all purchases. Now if you can just find out how to do a high pH tank with a calcium reactor constantly chugging out solution. I mean I guess you can equally just chug out a lot with of kalkwasser but half the point of a calcium reactor is to get away from other "dosing" options.

[@boomcar911]

What court ruling? Isn't there always sale tax?

[@Mike__B]

@@boomcar911 South Dakota v. Wayfair was a Supreme Court decision that makes it easier/legal for states to go after online retailers for them to collect sales tax on behave of the state even if they don't own a physical presence in that state.

Hey!

I think you're going to end up with a bunch of dead coral if you try to run alk that high in a low nutrient tank haha

[@Reefahholic]

Makes some corals look weird. Strange.

[@Reefahholic]

BulkReefSupplyCom - Yeah for sure. I bet amino’s would have boosted growth a bit more. Interesting to say the least. :-)
