Just about ready to throw in the towel grrr

I find the statement "my tank never looked better and then I started zeo" very interesting. Why use zeo if your tank was looking good? I was going to give zeo a try but I just can't justify the cost nor the commitment required to do it. If any mistakes are made with zeo..... lights out so to speak. I'm not in for that.

I'm going to be in Calgary over the weekend.

If anyone wants to meet up over lunch for a ZEO instructional, I'd be happy to share.

Not a bad idea.

I would try to get in on that (depending on where/when I guess!!)

Zeo is what really kicked my tank into high gear, when I started zeo I saw a lot of good changes, better water quality and colour/growth.

I have been very strict about my dosing regiment and change 5% water weekly with RBS (zeo guide recommends 10% with other salts)

I am running a euro reef rs135, it is a decent skimmer allthough I wish I had a bubble king, but for the price this skimmer works well.

Personally I think your skimmer is your problem, I really don't think a ER 135 is big enough for a 90 gallon + sump system when using Zeovit. Although it may be a good skimmer for the price it just simply will not do what you're expecting it to. Basically you're flooding your tank with bacteria and bacteria food to eliminate nutrients but there are harmful byproducts that need to be skimmed out. It seems fairly obvious to me that skimming has not been effective and these byproducts along with excess bacteria and b-food has resulting in a cyano outbreak.

Although the guide does state that 5% weekly is fine when using RBS it also states this would be for the purpose of only replacing elements. In your case you should change more water to help remove byproducts and excess bacteria and nutrients not removed by your skimmer.

With sump minus displacement of rock my system is only about 100G total water and I am only lightly stocked so the ER should be sufficient, I would love to upgrade to a BK but the $1000 price tag is holding me back. With the ER and weekly changes I should be removing enough of the bad nutrients to compensate for not spending my mortgage on a new skimmer.

As I noted earlier in exchange for my regular 5% water change this weekend I am planning on doing a larger removal and replacement upwards of 25% volume.

That's exactly what Euro Reef was counting on when they came up with that rating, plus they didn't make that rating for a zeo tank. I'm not trying to cut you down, nor am I telling you to break your bank, I'm just being straight forward. If it was sufficient you probably wouldn't have the cyano outbreak. Your best bet would be to cut back on the zeo until you get things cleaned up.

So how much of a ratings-upping should you look for, maybe about twice? Ie., look for 200g if you have 100g? I realize skimmer ratings have gotten better in recent years but I still take a skeptical view towards manufacturer ratings.. something of a black art methinks..

Even Bubblekings ratings are suspect. I have the supermarin 200 which is rated up to 400g and I find it is a little small for my system of around 200g total. I now wish I had gone with the supermarin 250
