cyano disappear

[ai[k²]wan]

hey guys,

the cyano on my sand bed is disapppearing and disappearing , used to be quite covered with it, and now some green algae is covering on the patch dat used to be cyano. have not done anything except maybe started dosing kalk for the past 1-2 week. refugium running as normal. or maybe.. bcoz i did not feed the tank for 3 days

cutting down on feeding will reduce the fuel for cyano

[ai[k²]wan]

i din expect it to haf so much impact. anyway, i started heavy feeding once again. see what happens.

wad is cyano?

[Tanzy]

Cyano is cyanobacteria a.k.a. red slime. Sometimes green.

Easy come, easy go.

mine easy come, dun easy go leh, how?

[Jun Hong]

I believe the kalk drip also help to reduce cyano. It keeps the pH elevated. By adding Kalkwasser on a regular basis (make-up water) and doing water changes every 2 to 3 weeks, I have found my pH to be consistently between 8.2 and 8.4. Keeping the pH at this level makes it less likely that micro-algae will become a problem since it will make phosphates into insoluble form.

Yes, dripping kalk will help to precipitate phosphates thus cutting one of the "fuel" for nuisance algae to grow.

When I changed the MH bulb from 7000K to 14000K the cyano went along with hair algae

[blacknails]

I thought cyno to green hair algae is a process all tanks go through once the water conditions stabilize?

[Tanzy]

If you manage the tank properly and be patient, the tank can avoid cyano and a large hair algae bloom altogether.
