So I’ve actually had some diatoms/algae growth on the glass of my tank for a few weeks, but my pods have been doing a great job of keeping it in check and cleaning it out. Now it’s started to appear a little on the rockwork (one rock so far) and in limited areas of the sand bed so I figure it’s about time to get some cuc. What would be best to add in my 125 gallon fowlr?
