280g Inwall

[Aquattro]

Tony, as per our chat yesterday, this is the dosing schedule G. Alexander had suggested for my 200g water volume...

~1.9l of zeolites, water flow ~ 200 US gallons per hour changed at 6-8 weeks. If you have recently started zeovit I would recommend to run the reactor with a 3 hour on / off interval for the first couple of week

0.75 liter activated carbon flown passively

Dose Coral Vitalizer @ 4 drops/2 x weekly

Dose Amino Acid HC @ 4 drops/2 x weekly

Dose Zeostart2 @ 0.7 ml 2 x daily

dose Xtra @ 4ml/ 2 x weekly

Dose Zeobac @ 8 drops twice weekly

Dose Zeofood7 @ 4 drops twice weekly

Agitate reactor once daily

I'm also a huge proponent of new clean rock from the real live ocean! Rock will adsorb nutrients over the years, and using any used rock, dry or otherwise, can and often will lead to algae issues. Yes, you save a few bucks, but I find saving a few bucks in this hobby often has a cost.

I don't think the zeo system works on the more is better principle, and I suspect that it will eventually work for you, but you have a ton of PO4 to suck out first. GFO may help accelerate that, or perhaps change your zeolites more often.
Not sure about running both, never tried it, but starting with new rock (20% maybe older from previous tank), running zeo from the start, my PO4 is 0.02 or lower. I also change 25% of the water biweekly.
