Is CLR safe to use in aquariums2007-11-24 23:37:13

Is it sealed with silicon or that black sealant?

do what FreeBird said! No CLR!!

Bleach is safe to use in and on all your aquarium items including the glass, but you've got to be sure to rinse it thoroughly, like at least 4 or 5 times, if there is any trace of bleach left on the inside of the glass, the water will dilute it and definitely kill the fish. Bleach has been used by 3 pet stores I know of for years and cuts through any algae, film, or any kind of residue.

What are you talking about

---

No to the CLR or bleach or any other detergent. try letting it soak even in normal tap water for a day the using a hose with some pressure and a clean sponge, the kind with the rough green stuff on the back.

never use chemicals on an aquarium that will be used for fish or amphibians.

Chemicals are never a good idea to use on an aquarium, depsite how much you rinse. What always works for me (and I've got some OLD tanks) is some aquarium salt (it's made especially for freshwater tanks, used for cleaning tanks and treating your tank water) and an algae sponge. Using the salt directly with a little bit of warm watter and gentle scrubbing with the algae sponge (don't scrub too hard or you'll scratch the glass) does wonders for mineral build up, as well as any algae stains you might still have.

most ppl are going to say no but me ive used almost every thing in my aquarium to clean it with out killing my fish all you got to do is rinse it out real well and ive kept all kinds of fish the best thing to use really is viniger or speacial cleaners designed for aquariums but as long as you rinse it out really well it shouldnt hurt it

---

Just use Clear/Pure (non-Surficant/Sudsing) Ammonia mixed with water to wipe down your emptied out aquarium (because it will nitrify when you fill water back up for cycling).

Do not use Soap, and though CLR is good for many things I would not use it to clean my aquariums or my equipment with.

---

Use a straight edge razor to scrape off anything from the glass.

It is possible to use it if you are very careful with rinsing. The trick is that you have to wet a paper towel with it, lie it on the glass, and cover it with plastic wrap overnight. Many of the chemicals in CLR evaporate before they have a chance to work.
