280g Inwall

Hmmmm, no, I don't think so ... Although I guess it is something like 16 though. I buy whatever fits in a 1 gallon container and this seems to be about 7-8 lbs and I have to replace it .. hmmmm I need to take better notes, but I think it's twice a year. Man, now you have me thinking. It definitely hurts the wallet when I need to get more.

I wouldn't be able to afford changing mine every week

The HC GFO I just used up came from Chin_Lee's group buy
3lbs gave me 6 cups, so 6 4week uses
In the future I plan on using the BRS calculator's recommended 0.86 cups for my 110g system, so hopefully 10 cups/5lbs will get me a year's use

No, I guess you're right. I measured out a cup and it came to about 250grams. So that's the same weight as yours.

However, keep in mind that I'm not changing out the full recommended volume of gfo per week. The RC calculator for example says for my tank volume I should be using about 2.5 cups and changing it out every 4 weeks. Instead I use a smaller volume and change it out every week or two. So it kind of works out the same (not quite, but close-ish). The equivalent in your case assuming a 75g tank volume would be something like 3 tablespoons per week, or 50 grams, I think. I probably have my math all wrong on this but something like that anyhow..

No, your math is good on my amount needed, but maybe 3.5Tbsp/week
You have me pondering running a half dose bi-weekly. It'll be interesting to see how 110ml tumbles. I suspect it would clump less

Did Kien attempt a FTS ?

The tank is still running.. It's been a bit of a tough few months with it lately, mostly on account that PO4 will run rampant and the only way to keep it under control is GFO which gets expensive. The fish are all doing well, getting bigger and bigger. I can understand why one would want a bigger tank than this even, it's just too bad it's getting to be such a cost prohibitive hobby in so many respects. In some ways I'd love to go bigger, but it's not ever going to happen.

So for this tank been running a few years now, I have a few changes planned for the next few months.

Most notably, I want to get a skimmer neck cleaner online and maybe get back into using a calcium reactor because I'm not overly enamored with 2 part dosing. Have the parts for a skimmer neck cleaner all put together, just haven't done the actual assembly yet.

Also switched to LEDs about a year back and to be honest I miss the Radiums. But they were getting too hard to buy so I figured what the heck.

Also wondering if dosing kalk might help with the PO4 issues.

Would kind of like to invest in some new rock and rework parts of the reefscape.

Also bought some wet floor sensors to let the Apex alert me if there is water spillage.

No shortage of things to do; just been battling a nasty head cold the last month and it's been wiping me of all energy. Summer before that and that's never good for my tanks for some strange reason. Anyhow hopefully soon I can get the ball rolling and maybe post some better updates.
