Don't track only half your reef's money story
The hobby quietly drains your wallet—the "reef tax" of salt, frags, and one more pump you'd rather not add up. But your corals are worth real money too. Meta Reef's reef tank spending tracker shows your true spend and your live reef value in one place, so the honest number stops hiding.
Log expenses by category
Record livestock, equipment, salt and additives, food, dry goods, and more. Every purchase is filed so the true cost of the tank stops being a mystery.
Totals by category and over time
See where the money actually goes—and how spend adds up month over month—so you can plan upgrades and spot the categories quietly draining the budget.
Per tank or across every tank
View spending for a single build or roll it up across all your tanks for the honest number: what the reef habit costs you altogether.
Reef value from live listings
Meta Reef estimates what your corals are worth right now, priced from real, current marketplace listings—so spend and value sit side by side.
Two sides of the same reef: spend and value
One half tracks what you put in. The other estimates what you have to show for it. Together they turn the fuzziest question in the hobby—"what is this tank really costing me, and what is it worth?"—into two numbers you can actually see.
Spending
Categories you can track
Tag every purchase to a category and a tank. Meta Reef totals them so the true cost stops hiding across a year of small orders.
- LivestockCorals, fish, and inverts—usually the category that surprises people most.
- EquipmentPumps, lights, skimmers, controllers, heaters, and the upgrades that follow.
- Salt & additivesSalt mix, dosing supplements, and the recurring chemistry that keeps the reef running.
- FoodFrozen, pellet, and coral foods—small tickets that add up steadily over the year.
- Dry goodsMedia, test kits, plumbing, frag plugs, glue, and the miscellaneous consumables.
- Everything elseAquascape rock, sand, and any one-off purchase that does not fit a neat bucket.
Reef Value
Priced from live listings
Meta Reef estimates what your corals are worth right now by connecting your livestock inventory to real coral listings—so value tracks the market, not a number you typed once.
- 1
Catalog your livestock. Add the corals you own to your tank's inventory.
- 2
Connect to real listings. Your inventory links to live listings from the Meta Reef marketplace.
- 3
See spend vs. value. Your estimated reef value sits next to what you have spent, updated from current prices.
Reef Value is an estimate priced from live marketplace listings, not an appraisal or a guaranteed sale price.
Track your collection like the investment it is
Your corals aren't just livestock—they're a growing collection worth real money. Meta Reef prices every coral in your inventory against 10,000+ live listings from stores and fellow hobbyists, then keeps that number current as the market moves and your colonies grow. No spreadsheets, no guessing what you'd get for a frag.
- Priced from the live marketplace
Each coral is valued from what comparable frags and colonies are actually listed for right now—not a number you typed in months ago.
- Updates as the market moves
As listing prices shift and your colonies grow out, your reef value moves with them—so it's always a fair read on today, not last season.
- Watch your investment over time
See value climb as you frag, trade, and grow—and know exactly what your reef is worth before you ever sell a colony.



The true cost of the tank, no longer a mystery
Reef keeping spends money in a hundred small ways—a bucket of salt here, a frag there, a replacement pump when one fails. None of it feels like much on its own, which is exactly why the yearly total tends to shock people. Logging expenses by category turns that blur into a figure you can actually plan around.
And because your corals connect to the Meta Reef marketplace, spending is only half the story. You also see what your reef is worth today, priced from 10,000+ live listings across stores and fellow hobbyists—so the question is no longer just what it costs, but what you have grown.
Spending & reef value FAQ
How much does a reef tank cost to maintain?
It varies widely with tank size and stocking, and the honest answer is that most reef keepers underestimate it because the spend is spread across salt, additives, food, replacement equipment, and new livestock over many months. Meta Reef removes the guesswork: log each purchase by category and it totals the ongoing cost of your tank so you can see the real monthly and yearly figure instead of a hunch.
How can I track my reef tank spending?
In Meta Reef you log expenses against a tank and tag each one—livestock, equipment, salt and additives, food, dry goods, and more. The app rolls those up into totals by category and over time, per tank or across every tank you keep. It is free, works on any device, and turns scattered receipts into a clear picture of what the hobby actually costs.
How much are my corals worth?
Meta Reef estimates the current value of your reef by pricing your livestock inventory against live listings in its coral marketplace. Because the corals you catalog connect to 10,000+ real, active listings from stores and fellow hobbyists, the value reflects what similar corals are selling for right now—not a fixed guess you typed in months ago.
How does Meta Reef value my corals?
When you catalog corals in your livestock inventory, they link to real coral listings across the Meta Reef marketplace. Reef Value is estimated from that live listing data, so as prices move and as your colonies grow, your estimated reef value updates alongside them. It is an estimate priced from the market, meant to sit next to your spending so you can see spend versus value at a glance.
Can I track spending across multiple tanks?
Yes. Every expense belongs to a tank, and Meta Reef rolls them up across all of your tanks into one total—what the reef habit costs you altogether. You can drill into a single build or step back to the whole rack, and there is no limit on how many tanks you track.
Is it free?
Yes. Expense tracking, category totals, and Reef Value are all free, with unlimited tanks and no hardware required. You can create an account and start logging spending in a couple of minutes.
