Fish are a lot more expensive and balancing the water is much more time consuming than freshwater! The a$$ hat above is a jerk! **Q: How much clearance do you need on top to access filters etc...** A: lets say the filter sponges are around 8 inch long and lift straight up in the center so lift the lid off and then filter 8 to 12 inches but you could go tighter if your good and not clumsy **Q: What are the pump specs? and should I upgrade?** A: Pump Output : 810 L/h (214 US Gal/h)- 120V/60 . remember the filter is set up to operate thru sponge so you realy dont want to speed up. i just had a friend ask and we are working on adding a fluval 307 i may drop down to a 207. Better to add a canister. **Q: Can you use this aquarium for freshwater or does it have to be saltwater ?** A: the LED is the saltwater version lighting so could cause algea issues in fresh. You can buy a replacement Aquasky LED. And yes you can run frest water just dont leave the light on to long you will get algea . ## Frequently Bought Together - Fluval Flex 32.5 Marine Salt Water Aquarium Kit - Fish Tank for Fish, Coral & More - Comes with LED Lights, Filtration System & More - 32.5" x 15.75" x 15.35" - 123 L, 32.5 Gal. - Black - Fluval Sea PS1 Protein Skimmer for Aquarium, for All Breed Sizes - Fluval M 150-Watt Submersible Aquarium Heater – Reliable, Compact Heating with Mirror Technology for Fresh & Saltwater Tanks Up to 45 Gallons --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/355101422-fluval-sea-flex-saltwater-aquarium-kit-123l-black](https://www.desertcart.sc/products/355101422-fluval-sea-flex-saltwater-aquarium-kit-123l-black) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-10-07*
