hi zhangg - I'll have to go over my records, i think its around 60 -70 ml a day of both solutions. I supplement with Kalk now too. SPS is growing well, and when I test - Alk is usually around 9 and Calcium is usually 430+.
I'm at the point where I really need to recalibrate, but I'll be moving in a month, so most likely going to leave it as is for the time being.
I also have a ton of sps and 3 clams, so my dosing needs maybe higher then yours.
thats just straight up nastly lol... gotta love it.
I did find someone however to trade my BK mini 200 for a 160, but i think i def want one of those swabbies for it with the locker! My wife will either really be happy about it or... hate me lol.
If you get it with a pinwheel, absolutely. The mesh wheels only last a few months. My current pinwheel has been running for 9 months so far without a single issue. Works the best in about 7 to 8 inches of water. It has been a bargain for how it has performed. The skimmer is easy to maintain and clean. Can be taken all apart in about 5 minutes. Would certainly recommend it.
