I recall buying some slugs that supposedly good at eating algae a while ago. Kenny help to arranged a group buy. Didn’t see it for many months . Just saw it next to the snail. Pretty cool Edit - found the old thread . Jelly bean slug - bought back in 2022.

This is from BRS: For most reef tanks that are no more than 2-3 years old, phosphate levels should be kept very low in order to avoid problems. You’ll find recommendations ranging from 0.02 to 0.05 ppm are the most common answer. Phosphate (and nitrate) is something I find very hard to hit any...

I don’t disagree . But I had same issues when my phosphate is ard 0.2. I only addef gfo temporary to bring it down. Is there a target range i should shoot for? 0.02 is too low, 0.2 too high?

While figuring out what is the source of zinc, i ordered a small package 100g of Cuprisorb ( i read that i will remove copper + zinc) . Should be here tomorrow . I am trying to avoid drastic change as i'm heading out for a week.

Not sure if I can find if there is any screw in the back AIO chamber. That said , I do have media bags that have metal zipper(?) . I’ll replace all media bags just in case. Edit ; zipper is plastic .

Sentosa seem to recover but stylo now showing sign of stress. Arg… ICP results attached. We know about high salinity (fix) and low phosphate . Low in some trace ( iron, Fluoride, iodine …) , high in Zinc. I bump up my trace elements dosing. Anything else stand out I should address?

I’ll take an order of pods in Jan. Can I tag on to your order?

I just measure the tank and it’s at 0.06 . I expect it will increase with heavy feeding and no gfo. I’ll let it ride. I’ll get the ICP in a couple of days. Hopefully it will shed some light into the issues.

I still lower the salinity a tad. I read up on high ca (500) and mag (1500) level , and most ppl think it’s not an issue. I’ll leave it and let it come down naturally. I’m going to leave town in a week and hate making more drastic change.

1.0265 is not crazy high. Right?

Bingo! I calibrated the Milwaukee recently. I’m at 1.0265 with the trusted hydrometer and 1.024 with Milwaukee.

Yes. Fresh sw have high ca and mag. I’m using aqua forest salt

Ordered a new salifert calcium and mag test. I knew I have high ca and mag, but didn’t realized it’s really high. My previous test kit is 2+ yrs old and expired. Ca - 490 Mag - 1500 I got really curious where the high mag comes from. I do dose 1-1 ca and all, so my fault really following...

Nice to know. Thanks!

It won’t ship in time.

Nope. Filter with paper coffee filter and it’s still brown. Going to bake arm and hammer baking soda . Seems easy enough.

You’re probably correct. The brown stuff settled and also coat the side of the jug.

What’s the main chemical compound? Sodium carbonate and sodium bicarbonate are the 2 common ingredients. What’s the in the fauna Marin stuff?

What do you dose for alk ?

my Alk is not that high. I can slowly reduce it to 7.5
