Just about ready to throw in the towel grrr

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.

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.

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.

Greg,
are you using RO water? If not the spring run off time is really bad for extra chemicals in the water our reefs don't like. I am having a similar battle as I neglected to change my RO filters soon enough.

Snappy, great point. I'll need to test my RO and see if the TDS have increased. I haven't changed the filters in a while.

I can't get those stupid quick connects apart without breaking them so changing filters means I need to replace half the fittings on my filter.

Wouldn't make much sense to use tap water and zeovit, kind of like putting regular gas in a Ferrari

I use only RO/DI, but I have not made up any fresh in a couple weeks as I have a 60G rain barrel that is now about half empty. I might find a higher TDS as I make more water later this week.

Gotta agree with Snappy.

Change out your filters, flush your RO membrane and change your DI resin. In 2 weeks you should be back to normal. If I see algae starting in my tank it is always because of the RO unit, regardless of the TDS (which can vary greatly depending on the device used to measure). Do this and the algae will go away by itself.

Also, I would not recommend storing your new RO water in a rain water container that long (more than 24-48 hours) if it is not food grade. Good luck.

I had a beautifull 1 year old tank with ZERO alge and growing SPS with very nice colors.
Then ZEO "miracle" came to our land.My tank is now full of red hair algae.
ZEO rocks are just NO3 and Po4 Factory, at least it was to me similar to BIO balls.

I had corresponding flow to my tank size throu the rock , regular shaking, RO/DI water only with TDS @ o-ppm, marine pro salt, fresh T5 bulbs, water change every 8 days, two skimmers 600 L/air /hr each, 90x times display tank flow turnover. Sal 1.024, Ph always 8.3 day above 8.1 night.
I feed my sps regulary with variable diet.

I was never able to find a sweet spot between carbon and bacteria doisng, so I got rid of ZEO rocks and will never go back to it.Still use some suplements like Sponge, Amino acid etc. Just because i still have it.

3 weeks without ZEO rocks, cut down light first two days no loight at all, now down to 3hrs a day, vigorus Po4 removal and manual algae removal, seem to improve overall tank condition.

For red cyino though I use ZEO-bak soaked in ZEO-snow seems to help.
Will never use ZEO rocks again.
Not to mention large SPS loss due to a tiny bit more flow that I tried for few days. Lost about 400$ worth of SPS in 4 days like a snap !.

Still have 2/3 of a bag of zeo rocks if anybody wants it.
