How Budget and Premium differ
Only the items that change are shown. Everything else is the same in all three tiers.
On a 75, the cheapest reliable item we found for each slot is also our best-balance pick, so Budget is the same list as Mid-range. To spend less, look at the Marineland ensemble below: it replaces the tank, stand, lid and light for less than buying them separately.
| Item | Budget | Mid-range | Premium |
|---|---|---|---|
| Heater | Eheim Jäger 300 W adjustable heater $39 | Eheim Jäger 300 W adjustable heater $39 | Fluval E 300 W electronic heater with display $73 |
| Light | Hygger HG978 Advanced Spectrum LED, 48–54 in, 42 W $68 | Hygger HG978 Advanced Spectrum LED, 48–54 in, 42 W $68 | Fluval Aquasky 3.0 Bluetooth LED, 48–60 in, 35 W $160 |

Why some tiers reuse the Mid-range pick
- Budget, filter: Same as Mid-range: the Tidal 110 was the lowest-priced filter rated above 75 gal that we found, so it's also the Budget pick. The AquaClear 110 is a good alternative.
- Premium, filter: Same as Mid-range: a canister filter adds media room, but the Tidal 110 is already rated to 110 gal, so it isn't a meaningful gain on this tank.
- Premium, stand: Same as Mid-range: pricier stands are about looks, not function.
- Premium, tank: Same as Mid-range.
- Premium, substrate: Same as Mid-range.
Budget is the cheapest reliable option that meets the requirement. Mid-range is the best balance. Premium has to add a real gain, or it reuses the Mid-range pick.
What the Mid-range list costs to run
About $15.61 a month, so the first year comes to about $1,344 including setup. That's 354 W of rated equipment (84.7 kWh a month) at 17¢ per kWh, with the light on 8 hours a day and the heater on 30% of the time, plus supplies. Food isn't included.
| Electricity | $14.41 |
| Testing | $1.08 |
| Water conditioner | $0.12 |
| Total per month | $15.61 |
The 75-gallon running-cost page works through the same tank line by line with a typical calculator setup, so its figure differs slightly from this exact list.
Is a starter kit cheaper?
The Marineland High Definition LED Ensemble, 75 gal costs about $495. Adding what it lacks ($130) brings it to $625, against $845 for the same items in our Mid-range list, so the kit path is $220 cheaper.
Marineland's description and PetSmart's “Includes” list name the tank, stand, glass canopy and LED only. A few retailer listings also mention a filter, but those two don't, so we count the filter and heater as missing.
| Part | In the kit | What changes |
|---|---|---|
| Tank | 75-gal glass tank, 48⅜ × 18⅜ × 21 in | Included: replaces our row |
| Stand | Farmhouse-style cabinet stand, 50 × 20 × 28 in | Included: replaces our row |
| Lid | Glass canopy | Included: replaces our row |
| Light | Hidden LED light with daylight and moonlight modes: fine for fish | Included: replaces our row |
| Filter | Not included | Missing: add ours, +$91 |
| Heater | Not included | Missing: add ours, +$39 |

Contents: PetSmart product page: what's included.Good to know
- Heavy items: the tank, stand and substrate are expensive to ship. Local pickup often saves money. Filled, a standard 75-gallon tank weighs about 785 lb, so the stand has to be made for it.
- Not included: fish, coral, plants and cleanup crew; food, décor and light mounts; shipping and sales tax; electrical work, a GFCI outlet or a surge strip.
- Before you add fish: cycle the tank first, which usually takes several weeks. Test ammonia and nitrite until both read zero and nitrate starts to rise, then add livestock slowly.
