Last water change in June.

Recently I got tired of my tank and was going to sell it, then decided to keep it and am back into doing regular maintenance with the exception of water changes.

I havent done a water change in almost 6 months. however, I do dose additives based on needs after running full spec of test.


My tank is the healthiest it's been since i put it up (tank is now running since april) I have a couple SPS's but mostly LPS dominated tank. My corals are growing and I have 9 fish and they are very happy.

I see people here who do water changes once a week and post about people stressing about how important they are. I havent done one in months.


My question is, why are water changes important if your levels are good, your corals are growing and your fish are happy.

Side note, i will be doing a water change (30% over the weekend) and dont plan on doing the next till may

Hmmm I wonder what will happen after you do that water change

Get before and after pictures.

post pictures, I do a about a 35 gallon water change on my 75, once a month

how is this possible if i don't do my regular water change my fish and corals get grumpy lol

What are your nitrates at?

after reading this thread this morning. I tested nitrates, my nitrates are at 20-30 ppm..


For everyone else, I'll do something better. I'll take HD videos before and after

U got a DSB? What equipment/fuge are u running.

There's plenty of products ( aqua Bella ) that guarantee no water changes for 1 year. The stuff ur adding is prob similar to that product.

I've done a water change in my 175g tank it's prob been a good year that no one changed the water did anything to tank I don't understand how all my fish lived no joke

i have a 3 inch DSB..

equipment is in my signature. my fuge has bottom layer sand, top layer miracle mud, some live rock and chaeto.

as far as what im dosing, I only reall dose alk and calc to keep levels right.

your nitrates are really high. you should really consider regular maintenance.

Its not that bad for an LPS dominated tank.

Yea if your not keeping SPS 20-30 isn't bad at all, in fact some corals like a bit of nitrates or at least I've seen better growth that way.

i have a monito cap that i got after my last WC, it has been growing rapidly.

My nitrates never drop below 20 and I do 20% weekly WC. Plus u have natural nitrate export with the DSB and MUD so no surprise there.

But doesn't mud go bad over time?

You probably feed your fish very little or none at all. Water change is important to replenish trace elements and to lower nitrates etc. No one told you, you must do regular water changes. Fish and some sps can tolorate high nitrates especially monti caps. We're still waiting for pics...

thought you wanted before and after pics..

ill upload some before pics now, quality will be lousy, taking it with my phone.

Hey dba you mentioned doing a water change this weekend. Why? It seems you have a renewed interest in the tank again. Just pay attention to it and see how things go without doing a water change.

When i was younger my systems always did amazing when i lost interest and totally neglected them. Crazy things happened. Growth like ive never seen. Maybe your on to something.

I think the saying goes, "If it ain't broke, dont fix it".
