Acid Buffer
An acid buffer is a product used to lower and help stabilise the pH of aquarium water. It’s especially useful if your tank water is naturally too alkaline (high pH) for the fish or plants you’re keeping. In many cases it’s used together with an alkaline buffer to set and maintain a specific pH range that’s right for your setup.
What It Does
It lowers pH by buffering your water; this means it helps resist sudden pH changes once adjusted.
In products like Seachem Acid Buffer, it also converts carbonate hardness (KH) into plant‑available CO₂, which can benefit planted freshwater tanks.
Works best when matched with an alkaline buffer (like Seachem Alkaline Buffer) to dial in a target pH range without big swings.
Most acid buffers are phosphate‑free, so they won’t promote algae growth.
Where It’s Used
Freshwater planted aquariums with hard, high‑pH waterTanks where a specific lower pH range is desiredAs part of a pH adjustment routine during water changes
How To Use
Start with small doses and test the water before and after adding the buffer.
Follow the dosing on the label - for example, many products suggest ~2 g per ~80 L of water as a starting point.
If using with an alkaline buffer, you can target specific pH ranges by adjusting the ratio of the two.
Alternatives & Related Products
Aqua Clean Acid Drop Buffer – another acid buffer option for lowering pH.
Waterlife Ph 7.2 Acid Buffer – buffer aimed at a specific target around pH 7.2.
Seachem Acid Regulator 1Kilo – similar purpose for general pH lowering.
API pH Down – liquid alternative to powder buffers.
Essentials Lab Buffer 7 1L – liquid buffer solutions for precise pH adjustment.
Support products like Seachem Neutral Regulator help set pH to neutral (around 7) when used with both acid and alkaline buffers.
Tips
Always test your water (KH & pH) before adjusting. Make changes gradually -large pH jumps can stress fish.

Hailea Internal Filter
The Hailea Internal Filter (often referred to in product lines like BT‑200, BT‑400, BT‑700 or BT‑1000) is a submersible internal aquarium filter meaning it sits inside the tank and helps keep the water clean and healthy for your fish and plants.
How It Works
Internal filters like this pull water from the aquarium, pass it through media (sponges, carbon, etc.), and then return the cleaned water back into the tank. They typically offer three types of filtration:
Mechanical filtration: traps solid particles and debris.
Biological filtration: provides space for beneficial bacteria that help break down harmful ammonia and nitrites.
Chemical filtration: activated carbon media removes impurities and odors.
Key Features
Submersible: fully underwater and attaches inside the tank, usually with suction cups.
Aeration: many models also help oxygenate the water as it circulates.
Durable construction: often made with reinforced ABS plastic and sealed motors to prevent leaks and long‑term wear.
Energy efficient: power usage varies with size (from ~3–20 W depending on model).
Choosing the Right Size
Internal filters come in different power/flow ratings:
Smaller models (e.g., ~200–400 L/h) are good for nano or small aquariums.
Larger ones (e.g., ~1000 L/h) work well for medium tanks.
Why Use One
An internal filter is a great solution if you want:
A simple, compact filter that doesn’t require plumbing outside the tank.
Better water clarity and oxygenation for your fish and plants.
A system that’s easy to install and maintain perfect for beginners.
