I had softies and easier lps do well with only water changes (20% every 2-4 weeks with a 70-80% change every 9-12 months) for about 12 years - leather coral that reached 20” across and mushrooms that multiplied to plague portions. I had a hammer coral that got to be volleyball size - I still have a portion of it. My purple torch grew many heads. The only welso I’ve ever been able to keep alive arrived back then - it’s 13 and thriving now. A purple stylo that I had did quite well, but most acros just stalled out and eventually died. Lighting is critical too.
I started dosing 4-5 years ago when I moved and could not keep my pH up due to increased co2 levels. - I fixed that by removing the gas’s heater from my garage, but have continued dosing and enjoying the added coral health.
- edit sorry just looked at the date. ancient post.
