Lellynelly Posted May 10, 2015 Share Posted May 10, 2015 Just wondering how often people change water, and what % of water each time. Does the frequency depend on what equipment you have? I have a 60 litre tank with one external filter containing live rock and one internal foam filter. no coral or invertebrates - just 2 clown fish Link to comment
cjm3fl Posted May 10, 2015 Share Posted May 10, 2015 Once my tanks were well seasoned I was OK with 10% weekly water changes. After cycled and before seasoned I'd do 10% every other day. My past tanks have been 10g, 20g, and 29 gallon Seahorse or Pipefish tanks. Link to comment
pgrVII Posted May 10, 2015 Share Posted May 10, 2015 I change 5 gallons out of my 40 every 3 weeks and everyone seems OK with that. Changing water is like getting new socks,just feels good. Link to comment
GMay Posted May 10, 2015 Share Posted May 10, 2015 Weekly 10 to 15% changes is waht I do. My only filtration on the JBJ 28 gal model is Purigen, Chemipure Elite and activated carbon replaced monthly. I mostly Zoas, two fish, snails, hermits, a favia, piporgan, GSP and clove polyp. The tank has been running this way for four days shy of a year. Picture is FTS a month ago.

bevo5 Posted May 10, 2015 Share Posted May 10, 2015 Also depends on your bio load. I'm running a fairly heavy load on my tank and do 15% once a week. A few weeks ago I noticed a ring bit of hair algae popping up so I've been doing two 15% changes a week since then just to squash out the problem. But a small load that is skimmed well could manage great with fewer changes. Link to comment

aviator300 Posted May 10, 2015 Share Posted May 10, 2015 I may not need to do this much but on my 13.3 gal tank which holds 10gal water (after sand and rock were put in), but i do a 2.5 gal water change weekly (every week). That's a 25% water change that i got used to doing during a hair algae problem and i've just kept it up ever since. Link to comment
Halo_003 Posted May 10, 2015 Share Posted May 10, 2015 I have a 12G and I do about 3G weekly. Link to comment
