So this year, I want to turn over a new leaf and make my tank more clean. For starters, WATER CHANGES. Ok so I've heard that some go without it, so me go with it, what should I do? For those that do not know my tank it is a 150g reef with a 75g sump, biological filtering. How much should I do on the tank and how often?

Second question, algae control. Ok so waaay back in the beginning I did algae scrubbers, but I didn't understand them quite as much with my 55g, and also a problem is that my sump tank on the 150g doesn't really have room for an algae scrubber in it's mid-section. could I put two on the back of the tank? Or do some of you have other ideas of doing it.

Thanks,


Amph :)

Also one more question is over Auto-Topoff's. Anyone have any ish-cheap recommendations/diy versions? I want to get one I'm just not sure where to start

In my frag tank I have never done a water change. I don't run a skimmer, I have seen the best coral growth. I am getting ready to setup another frag tank that is the same one. I am going to run a skimmer on the second one and do water changes and document growth in each. I am going to do this to get a clear understanding of what works and what doesn't.

I mainly don't run a skimmer due to the fact of how I've got pods and whatnot in the tank that I want to keep. I think I'll pay the DIY Algae scrubber topic that is somewhere on this site a visit and get a refresher.

I am a firm believer of water changes. I try to do mine at least every two weeks.

RuRoo, what percent of tank water do you usually change out per water change?

I think water changes are def must. I do 35 gallons a week and if I every get my change station set up will do 50 a week in the future. when I slack on my water changes I notice an increase in algae and stuff and notice a slow down and health of many coral and fish don't seem as happy. that's my 2 cents anyway

Zach,
I haven't done a water change on my 90 gal since Dec 2010. I do dose calc, alk and mag. I did this to see if I could duplicate what I've read on the internet. I'm very pleased with the tank.
On my 180, I do a water change 25gal each month. I am also very happy with this tank. I also dose calc, alk and mag.

So, can I recommend one way or the other? NO. You decide what you want to do.

Ok thanks Larry and murf, that helps me a lot. I think I'll still do water changes and play around with the % of water til I find what works.

Each of my systems gets a 10% water change a week and I over skim based on tank size. I no longer dose as the weekly water changes replenish everything

I have roughly 75 g total water volume and I change 5-10 g every 2 weeks.

Double float version. I've seen them on the forums a few times for cheap.

I bought one from autotopoff. I'm not a DIY kinda guy.

I have a 90 gallon tank with a 30 gallon sump and I am trying to do bi-weekly water changes. Tried the whole once a month water change for a year. now that I have been doing 2 a week, I have seen better growth. But not to much. I just wanted to keep my tank cleaner since I feed heavy

water changes are not a must at all. I change out my water because it is a great way to get piece of mind. If your corals and fish are happy then why change anything. Typically hobbiest change 10-15 percent a week. I have heard up to as much as 33 percent a week. you still want to keep the healthier bacteria's in you water so... I change 10% a week and 25% a month during my longer working trips. This allows me to not have to dose in any way. Changing out this much water keeps everyone happy and keeps my levels at a flawless average. 130 gal a week 300 gal a month makes it easy for the wife to maintain my system. i havent checked calc, alk, mag, in a long long time. It is a little more expensive this way but well worth the investment. Hope this helps
