Pukani Rock Volume How Much Is Enough?

For a new 65g (starting with fowlr...lol) and a 20g sump with refugium, I am strongly leaning toward Pukani rock - it should have enough detritus to "seed" the cycle... lightweight, very porous, and I'm told very easy to work (build aquascape).

But I've read where folks have bought the stuff only to find that they have too much, given there's so much more volume vs. other rock, Florida rock, Fiji or whatever.

Bulk Reef Supply suggested 3/4 lb per gal, but the dude I spoke didn't seen confident leaving me less than confident as to his guesstimate. :-( That said, I'm concerned that at roughly 50 lbs I'll have either too little to build a tall enough wall, etc... or too much waste. Either is an obvious issue.

Hoping to locate some reefers who have hands-on experience with this rock. I need to place an order by tomorrow (Fri, 9/16) to take advantage of a group buy opportunity and $5 discount coupon.

Thanks!

 

have a 90. orders 80 pounds. had about 25 to 30 lb left over. great rock. i was happy to have the extra as it gave me more selection to scape. and you can use the left over to sell/trade to local reefers. check out my build thread and i have pictures of all 80 lbs laid out. with a beer bottle for comparison. i would think you would be good with 40 lbs.

 

For a 65 gallon, order 30 LBS. Should be perfect, maybe a touch too much. Pukani is great rock!

EDIT:

The photo shows 45 LBS. Dimensions of tank are 48" x 24" x 24".

 

See my link in my signature. I have 45lbs in my 65g.

 

Very helpful but raises more questions.

I scanned your build thread but not sure I saw your final aquascape. What I see (early in the thread) looks good but I want a fuller and taller wall than I see - that said, impossible for me to tell from what you have laid out on the floor (the beer is distracting ) the volume but looks like lots.

Is the 25-30 lbs leftover from the early DT photo I saw?

 

Very nice but still think I want to go taller, if that's realistic - which I'm thinking with Pukani is possible? Yes?

 

not sure if you saw this picture. but this was my final design, had about 25-30 lbs left over i would guess.

 

I say get extra more selection then u can break it up and glue frags to it

 

Actually did miss this one. Very helpful. Thanks!

My 65g is 24" tall - your 90g is 21", if I correctly recall the specs on the 90g. Using your guesstimate of 25-30 lbs leftover...let's say you used 50 lbs (est.)

So, for me to get the same result I'm guessing I'd need at least 60 lbs.

Does that sound about about right?

 

i think 60 lbs will be to much. unless you want it packed to the gills with rock?
