I read enough on vodka dosing to decide to use it, for nearly a year and I go without water changes.
Tank has acans, hammers, frogpawns, favia, brains, ricordeas, anemones, montiporas, and a bunch of other stuff all alive.
What I read is that vodka dosing tends to lower alk not raise it, I read about the burnt tips and what not. Understanding or not understading enough seems to work for me.
I get a lot of my information from Reefkeeping.com
If you have a better site than please do share.

My parameters are dead on based on the above table and I try to keep them steady.
a Bubble Magus with PSK 1000 and a EShopps 200 with a PSK 1000 that are currently skimming simultenously neither one is ever clean is fine for me, a $800 skimmer would do exactly the same. I have actually seen skimmers selling for $400 to $600 with the same exact pump and these two skimmers retail for well over $600 together, some sites close to $1000.00 together. I paid $100 each and they work great.
I began carbon dosing because i have a ton of fish and bc i dislike water changes becoming a slave to a hobby is what drove me to quit years ago.
In nearly a year of carbon dosing i have not had any crashes, fish deaths related to poisoning or anything that would otherwise make me or anyone question the use of vodka in my tank other than the fact that I sometimes drink the vodka myself instead of dosing it to the fish tank.
I dont really have pictures of the SPS, I put them in the tank and eventually they are all white, only happens to SPS corals. I usually place mid leven in the tank on a frag rack until I have time to relocate them.
As I stated before, no disrespect to anyone on any board, if some harsh opinions will come from hardcore sps keepers that are deeply devoted and often times consumed by their tanks then their responses will be very passionate, personal and hypocritical of anything a standard hobbyist writes on the internet.
I love admiring the tanks of hardcore committed folks but I do not envy or wish upon myself what I personally consider becoming a slave to a fish tank, I am hoping that it is in fact possible to keep simple acropora in a fish tank with a ton of fish and a ton of lps and softies. That rare hard to keep Milli stuff is not for me but I do love admiring the tanks of others.
I am looking for the solution on how to keep a simple mixed reef, I am not interested in hard to keep, rare, exotic, challenging whatever we want to call it corals. I have seen first hand how some reef tanks take over a persons life, not for me.
I will take your advice and the advice of others and try to keep things simple, I must, if I complicate this hobby then I will get out. I rather lose $100 of frags than live a life of running to my tank because my ph went from 8.0 to 7.9.
Complicated hobbies are not for me, over time I will take a step back keep simpicity in mind.
And in regards to your bathtub water statement, where do you think the water you drink, cook, wash and bathed in comes from? So yeah, I guess I do use my bath water for drinking water, we all do.
You are going to get a bunch of different methodologies on the husbandry of SPS. Not all of them are right but sometimes mixing too many can spell doom. Just from reading your posts tells me that you haven't really studied the Vodka/carbon dosing method. You alk is too high but you say that "you read somewhere that alk between 8 and 11 is ok" YES IT IS but not when carbon dosing. High alk can lead to burnt tips, tissue thinning and death for SPS.
Water changes. Everyone has their opinion. I personally favor water changes on a normal schedule of 10% a week and a 50% every 6 months (that's when I clean out my skimmer and sump of detritus and overflow box). Reason being is organic and in-organic buildup (heavy metal and such) that aren't exported through regular skimming. You wouldn't filter your bath water as drinking water would you? Some people use fuges that have plant life that utilize these materials but then again you pull them out when overgrown as a means of export.
There are major differences between keeping LPS, softies and SPS. the first 2 do not require the same husbandry as SPS. SPS need more a low nutrient, low phosphate, High light and higher flow than LPS and Softies like zoo's and paly's. They tend to live on sandy lagoons and can expunge detritus unlike SPS that cannot and require flow to do so.
In a mixed reef, if you can attain the right environment for SPS your other corals will benefit also (except for the lighting requirements). Being able to keep Softies and LPS by no means makes it possible to keep SPS.
Question? Why are you carbon dosing? I do it becauseI have a large bio-load of fish and corals (mostly SPS and want to keep my nitrates and p04 down and it also benefits the growth of my SPS). If you don't have algae growth or cyano I see no reason to dose Vodka.
2 skimmers is useless in a 120g. Sell them both and get one good one. It will be more consistent than 2 skimmers competing for the same waste especially if you want to keep up with no water changes.
Keep your methods simple and you will have success. BTW Jackson is one of the better SPS keepers on many sites. He keeps some of the rarer sps colorful with crazy growth when others cant. His help on my tanks have been invaluable. But I tend to take what I need from our conversations and improve upon them. Knowledge is King!
Pics would also help us determine what is really going on (burn, color loss , rtn/stn, ect...)
