Review: GOOD PRODUCT - I bought a rena fish tank which looks great but didn't realize how expensive the bits and pieces for the filter was but I can say that these are a good price. They do work fab once bought.
Review: Cheaper than Pets Stores - This was the best price I found for these Crystal Cartridges and they are great at keeping the tank water clean throughout the month. Change them once a month and fish stay healthy and well.

## Questions & Answers

**Q: Will this help stop everything in my tank goin green as tryed everything ?**
A: I have an internal and external filter. I had tannin discolouration from adding new bogwood. I didn't find the cartridge very effective in clearing the water but when I used API Super Act Carbon Pouch, Size 6 in the external filter it cleared the water in about two days. I don't think you can ever fully get rid of algae only minimise it by cleaning the inside of the glass and reducing the amount of time the lights are switched on. The more light the more the algae will grow. Also having artificial plants instead of real plants will help. Certainly having an external filter and using the pouches will be more effective than the cartridges.

**Q: Does size 3 fit a 80litre tank? And is it c600?**
A: Sorry our tank was much smaller so ca't really help. Have you tried going on to the technical dept/ info at API

**Q: What is the actual size of the cartridge.**
A: just measured one : 45 x 30 mm for the top section and 25 mm deep
