Under that condition it holds its full 150L rating at temperature. Teco does not publish a broader curve of capacity across other ambient temperatures for this model — in a hotter room, or with a heavier lighting load than the 0.5 W\/L test condition, expect less than the full rated volume to be held at temperature.\u003c\/p\u003e\n\u003cp\u003eIndependent bench testing (not a Teco figure) recorded a TK150 pulling a 250–270L planted tank from 29.8°C to 27.5°C in around three hours — a data point beyond its own 150L rating, and one that came with a return pump and LED lighting rather than a heavier heat load. It's useful context for what the unit can do stretched, but the manufacturer's own rating is 150L, and that's the figure to plan a purchase around.\u003c\/p\u003e\n\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e fresh and saltwater aquariums up to 150L with a standard lighting and pump load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot suitable for:\u003c\/strong\u003e running with no water flow through the unit — it needs at least 400L\/h through it to cool safely and effectively.

A hotter room or heavier lighting will reduce how much volume it can hold at temperature.\u003c\/p\u003e\n\u003ch4\u003eCan I run this on a bigger tank if I don't push it hard?\u003c\/h4\u003e\n\u003cp\u003eYou can, but you're outside the manufacturer's rating and results will vary with your lighting, ambient temperature and flow. If your tank is meaningfully over 150L, the TK500 is the sized-for-purpose option.\u003c\/p\u003e\n\u003ch4\u003eDoes it need a dedicated pump?\u003c\/h4\u003e\n\u003cp\u003eIt needs at least 400L\/h of flow through it — that can come from your existing return pump if it has the spare capacity, or a small dedicated pump.\u003c\/p\u003e\n\u003ch4\u003eIs R134a an issue to use today?\u003c\/h4\u003e\n\u003cp\u003eNo — R134a remains a normal refrigerant for this class of chiller.
