I love this unit. DIY was easy and nice complete kit. I had to run a bead of glue around the body connector because it dripped, no big deal. I had another kalk reactor for a larger system but it wouldn't fit under the stand on my 100g. Looking forward to not needing to replace mixing pumps due to broken impellers. I will be adding more Avast products to my system.
The DIY kit was simple to assemble. The video does a great job. As far as operation effectiveness, it keeps the solution saturated 24/7. Works great!
Great quality materials. The assembly video is easy to follow and the unit was fun to put together. Will definitely buy from Avast again.
